If volatiles such as water vapor and carbon dioxide are added to a rock, what will happen to the melting temperature

Answer:

Sedimentary rock

Explanation:

Rocks found at the beach and near land surface are usually sedimentary rocks such as shale, sandstone, limestone, breccia e.t.c.

Now,these rocks are formed from the porosity destruction through compaction & cementation process of unconsolidated sediments by calcium carbonate cements in the tidal zone occurring primarily in the tropical and subtropical beaches. Various crystalline forms of Aragonite and calcite, are the primary agents of hardening and bonding of clastic sediments by the precipitation of mineral matter formed in the pore spaces.

The rock Kelly found on the beach has been sedimentary rock. The rocks have been formed by the series of events including melting, erosion, weathering, and compacting.

The rocks are the hard piece of matter that has compact structure. Rock has been of there types, namely igneous, metamorphic and sedimentary rocks.

The rocks that has been found near the seashore has been sedimentary rock as they have been formed with the erosion and the compacting of erode with the weather conditions resulting in the rock.

The rocks have been formed with the process of melting, eroding, compacting, and deformation. The rocks form has been interchangeable.

Melting and cooling of the metamorphic rock results in the formation of the igneous rock. The igneous rock has been weathered and sediment to form the sedimentation rock. The effect of heat and pressure over sedimentation rock turns it into metamorphic rock.

Explanation:

Answer:

1.64mL of 5.80M are added

Explanation:

First, we need to calculate total moles of acetic buffer. Then, with H-H equation, we need to find ratio of moles of acetate and acetic acid.

The moles of acetate increased are due the addition of moles of NaOH. Thus, we can find the volume of 5.80M NaOH that must be added:

Moles acetic acid and sodium acetate:

Acetic acid: 0.550L * (0.0215mol/L) = 0.011825 moles

Acetate: 0.550L * (0.0255mol/L) = 0.014025 moles

Total moles = 0.02585 moles = [Acetate] + [Acetic acid] (1)

H-H equation:

pH = pKa + log [Acetate] / [Acetic acid]

Where pH is 5.75;

pKa of acetic acid is 4.74;

And [ ] could be taken as moles of each species.

5.75 = 4.74 + log [Acetate] / [Acetic acid]

10.2329 = [Acetate] / [Acetic acid] (2)

Replacing (1) in (2):

10.2329 = 0.02585 - [Acetic acid] / [Acetic acid]

10.2329[Acetic acid] = 0.02585 - [Acetic acid]

11.2329[Acetic acid] = 0.02585

[Acetic acid] = 0.002301 moles.

Moles acetate:

[Acetate] = 0.02585 moles - 0.002301 moles = 0.023549 moles

Initial moles were 0.014025 moles, moles of acetate added (Due the addition of NaOH) are:

0.023549 moles - 0.014025 moles = 0.009524 moles of NaOH

Volume is:

0.009524 moles of NaOH * (1L / 5.80mol) = 1.64x10⁻³L = 1.64mL of 5.80M are added

A buffer solution is a solution consisting of a weak base and conjugate acid or vice versa. 1.64 mL of 5.80M NaOH must be added to increase pH.

Volume is the space or the area is occupied by a substance. It is calculated in milliliters, liters, etc.

Moles of acetic acid: [tex]0.550 \times 0.0215 = 0.011825 \;\rm moles[/tex]

And, moles of acetate: [tex]0.550 \times 0.0255 = 0.014025 \;\rm moles[/tex]

Now, the total moles = 0.02585 moles  (equation 1)

Using the pH equation the ratio of moles of acetate and acetic acid is calculated as:

[tex]\begin{aligned} \rm pH& =\rm pKa + log \dfrac{[Acetate]}{[Acetic \;acid]}\\\\5.75 &= 4.74 +\rm log\dfrac {[Acetate]}{[Acetic \;acid]}\\\\10.2329 &= \rm \dfrac{[Acetate]}{[Acetic \;acid]} \rm .....(equation 2) \end{aligned}[/tex]

Now replacing the value of equation 1 in 2:

[tex]\begin{aligned}10.2329 &= 0.02585 - \rm \dfrac{[Acetic acid]}{[Acetic \;acid]}\\\\10.2329[\rm Acetic \; acid] &= 0.02585 - [\rm Acetic \; acid]\\\\&= 0.002301 \;\rm moles\end{aligned}[/tex]

Moles of acetate is calculated as:

0.02585 moles - 0.002301 moles = 0.023549 moles

The added moles of sodium hydroxide are: 0.023549 moles - 0.014025 moles = 0.009524 moles

Volume is calculated as:

[tex]0.009524\; \text{moles of NaOH}\times (1 \;\rm L / 5.80 \;\rm mol) = 1.64 \times 10 ^{-3}\;\rm L[/tex]

Therefore, 1.64 mL of 5.80 M sodium hydroxide should be added.

Explanation:

· Remove stoppers and stopcocks when they are not in use. Otherwise, they may "freeze" in place. You can de-grease ground glass joints by wiping them with a lint-free towel soaked with ether or acetone. Wear gloves and avoid breathing the fumes. The deionized water rinse should form a smooth sheet when poured through clean glassware.

Glassware refer to any laboratory apparatus made of glass. When you are done using a glassware, wipe down the glassware to remove any cleaning solvent.

A lot of our laboratory apparatus are made of glass e.g beakers, conical flask, measuring cylinders etc. These glassware must be properly cleaned after use.

They are often washed with a solvent and particles of the cleaning solvent adheres to the glassware.

These particles of the solvent must be wiped to remove these particles of cleaning solvent that could contaminate a sample placed in the glassware.

Explanation:

The word equation for the formation of copper acetate is as follows;

copper + vinegar →  copper II oxide → copper acetate

Copper and vinegar  are reactants while the copper acetate is the product

Note that vinegar is a weak solution of acetic acid. Pure copper does not react with acetic acid (copper is less than hydrogen in the electrochemical series); however, a reactive oxide layer is formed upon exposure to air. This layer interacts with non-oxidizing acids to give green copper(II) compounds (DeMeo, 1997; Tétreault et al., 2003), a typical example of such compounds is the copper(II) acetate formed in the word equation above.

Acid rain forms new substances because it is capable of interacting chemically with surfaces. When substances are exposed to acid rain, they dissolve in water if they are soluble in acids to form new substances.

Answer:    

The prefix di means 2 and the prefix hexa means 6.

As per IUPAC rules you must use the prefixes to indicate the number of atoms of each element in the formula.

So, the proper name for the compound C2H6 is dicarbon hexahydride.

Explanation:

The balanced equation for the reaction of dicarbon tetrahydride with oxygen gas to produce carbon dioxide and water is  [tex]\rm C_2H_4 + 3O_2 \rightarrow 2CO_2 + 2H_2O[/tex].

A reaction is a process that involves the transformation of one or more substances into one or more different substances.

The balanced chemical equation for the reaction between dicarbon tetrahydride ([tex]\rm C_2H_4[/tex]) and oxygen gas ([tex]\rm O_2[/tex]) to produce carbon dioxide ([tex]\rm CO_2[/tex]) and water ([tex]\rm H_2O[/tex]) is:

[tex]\rm C_2H_4 + 3O_2 \rightarrow 2CO_2 + 2H_2O[/tex]

In this reaction, two molecules of carbon dioxide and two molecules of water are produced for every molecule of dicarbon tetrahydride and three molecules of oxygen gas that react. The equation is balanced because the number of atoms of each element is the same on both sides of the equation.

Therefore,  [tex]\rm C_2H_4 + 3O_2 \rightarrow 2CO_2 + 2H_2O[/tex] is the balanced chemical equation for the reaction of dicarbon tetrahydride with oxygen gas to produce carbon dioxide and water.

They release most of the oxygen into the atmosphere. Therefore, the correct option is option B among all the given options.

Photosynthesis is a method that organisms like plants utilize to transform chemical energy into light that may then be released to power the organism's activities via cellular respiration. A portion of this chemical energy is held in carbohydrate molecules, including such sugar and starches, which are formed by the reaction of carbon dioxide and water.

Photosynthesis is performed by the majority of plants, algae, and cyanobacteria; these organisms are known as photoautotrophs. Photosynthesis is accountable for creating and maintaining the oxygen concentration of the Earth's atmosphere, as well as supplying the majority of the energy required for life on Earth.  They release most of the oxygen into the atmosphere.

Explanation:

Normally, beta-oxidation of fatty acid occurs in the mitchondrial matrix, however, when the fatty acid chains are too long, the beta-oxidation occurs in the peroxisomes where the oxidation is not attached to ATP synthesis but rather transferred (i.e high energy electrons are transferred) to O₂ to form hydrogen peroxide (H₂O₂). This is the major difference between the beta-oxidation that occurs in the peroxisomes to that which occurs in the mitochondria.

Its density decreases

Its volume increases

Explanation:

You notice that ice floats on water, this means that its density is less. The mass remains the same because you did not add or remove anything. But what causes the density to decrease then? For density to change, there needs to be a change in either the volume or the mass of the object. Density is calculate by mass/volume. Since the mass did not change, the volume must have. So in this case, the volume increases. Hence, this is what causes it to be less dense.  :)

Answer:

73.07 grams of ammonia is produced.

Explanation:

In order to find the grams of ammonia produced, we need to find the amount of the reactants so that we know how much product (ammonia) the reactants (Hydrogen and Nitrogen) can and will produce.

First, we need to use the balanced equation to find the amount of moles equivalent to the 60.1 grams of Nitrogen that reacts.

To convert from Grams to Moles, we will divide by the molar mass (amu)..

60.1 grams of N2 /  2(14.01) grams  N2 = 2.144896502 moles of N2.

So, we know that 60.1 grams of N2 equals 2.144896502 moles.

       Now, we will look at the balanced equation and convert from moles of N2 to moles of NH3 in order to later find the grams of NH3 (ammonia) produced..

2.144896502 moles N2 *  2 moles NH3/1 mol N2 = 4.289793004 moles NH3.

     Now that we know the amount of moles produced of ammonia, we will convert to grams. We can do this by multiplying by the molar mass of ammonia which is 17.034 (N = 14.01, H = 1.008, ---> 14.01 +3(1.008) = 17.034)

4.289793004 moles NH3 * 17.034/1 mol = 73.07233403 grams NH3

This can be estimated to 73.07 grams of NH3 (ammonia) produced.

Answer:Specific heat capacity at Constant volume of Nitrogen =742.32JKg.K

Explanation:

The Specific heat capacity at Constant volume of an ideal gas is given as

c =Cv / M

Cv= Constant volue of gas

M= Molar mass

But  First, we determine the Constant volume, Cv  which is given as

Cv = 5/2R since Nitrogen is a diatomic gas, N2 where R= 8.314Jmol.k

= 5/2 x 8.314Jmol.K

=20.785Jmol.K

Specific heat capacity at Constant volume, c

c= Cv/M

M=molar mass = 28.0 g/mol.

changing to kg/mol =28/1000= 0.028kg/mol

Therefore c =20.785Jmol.K/0.028kg/mol

=742.32JKg.K

Answer:

A positive ion has fewer electrons, and importantly, fewer electron shells (since atoms usually lose electrons until they get down to an empty outer shell.) This makes it smaller than a neutral atom of that element.

A negative ion has more electrons, and importantly, greater electron-electron repulsion in its outer shell. This makes it larger than a neutral atom of that element.
