The conversion factors she could use to calculate the cost of gas : 33.037 gallon from Baltimore to Orlando

She will spend $74.33 on gas

Given

Shonda’s car : 27 miles per gallon

Gas cost = $ 2.25/gallon

Distance Baltimore to Orlando = 892 miles

Required

Cost of gas

Solution

Total gallon needed to get from Baltimore to Orlando :

892 miles : 27 miles/gallon = 33.037 gallon

Cost of gas :

33.037 gallon x $2.25/gallon = $74.33

25.4g of potassium phosphate (K3PO4) are formed.

Potassium phosphate is an inorganic salts of potassium and phosphate.

3 KOH + H3PO4 → K3PO4 + 3 H2O

Step 1: Convert from grams to moles using the molar mass.

Step 2: Use the molar ratio to determine moles of other substance.

Step 3: Convert from mole to grams using the molar mass.

Convert grams to moles using the molar mass

25.4g KOH (1 mol KOH/56.098g KOH)

= 0.3593mol KOH

Mass of H3PO4 produced

0.3593 mol KOH ( 1 mol H3PO4/3 mol KOH)

= 0.1197 mol H3PO4

converting mole to grams

0.1197 mol H3PO4 (98g H3PO4/1 mol H3PO4)

= 11.730g H3PO4

Mass of K3PO4 produced

0.3593 mol KOH (1 mol K3PO4/3 mol KOH)

= 0.1197 mol K3PO4

converting mole to grams

0.1197 mol K3PO4 (212.267g K3PO4/1 MOL K3PO4)

= 25.408g K3PO4

Hence, option b is the correct answer.

. Molecular species TEND to have reduced melting points and boiling points with respect to non-molecular species. Non molecular species, which include sodium chloride, and graphite, and diamond, thus have much HIGHER melting points than methane or ethane, or water, which are composed of discrete molecules.

[tex]\boxed {\boxed {\sf About \ 1.040 \ moles \ of \ nitrogen }}[/tex]

Explanation:

To convert from grams to moles, we must use the molar mass. This can be found on the Periodic Table. We have a sample of nitrogen, so look for N on the table.

Now, use this molar mass as a ratio.

[tex]\frac {14.007 \ g \ N }{1 \ mol \ N }[/tex]

Multiply by the number of grams in the sample (14.57)

[tex]14.57 \ g \ N *\frac {14.007 \ g \ N }{1 \ mol \ N }[/tex]

Flip the fraction so the grams of nitrogen will cancel.

[tex]14.57 \ g \ N *\frac {1 \ mol \ N }{14.007 \ g \ N}[/tex]

[tex]14.57 *\frac {1 \ mol \ N }{14.007 }[/tex]

[tex]\frac {14.57 \ mol \ N }{14.007 }[/tex]

[tex]1.04019419 \ mol \ N \\[/tex]

The original measurement of grams had 4 significant figures, so we need to round our answer to the same number of sig figs.

For the number we calculated, that is the thousandth place. The 1 in the ten thousandth place tells us to keep the 0 in the thousandth place.

[tex]1.040 \ mol \ N[/tex]

There are about 1.040 moles of nitrogen in 14.57 grams.

a. displacement = 6 km

b. velocity = 4 km/h

Given

a morning paper route

Required

displacement

velocity

Solution

Displacement is a vector quantity that shows changes in the position of objects in a certain interval of time. Displacement has magnitude and direction

Can be simplified displacement = distanced traveled from starting point to ending point

a. Since we only consider the starting point and the end point, we just need to add up the distances to the north

3 km + 3 km = 6 km

b. Velocity = displacement changes with time

The number of atoms in 1 mole of carbon = the number of atoms in 1 mole of boron is not true about one mole.

It is untrue to say that one mole of fluorine gas weighs more than one mole of oxygen gas. Fluorine gas has a molar mass of 38 grams per mole, whereas oxygen gas has a molar mass of 32 grams per mole, based on their relative molar masses.

A mole of a substance is equal to 6.022 × 10²³ of that substance (such as atoms, molecules, or ions). The number 6.022 × 10²³ is referred to as "Avogadro's number" or "Avogadro's constant."

Since boron has a different molar mass than carbon, the statement that there are the same number of atoms in each mole is untrue.

The ratio of the substance's mass to its molar mass is used to express the number of moles of an element.

Moles  = Mass/Molar mass

Given that the molar masses of carbon and boron differ, the statement that the number of atoms in a mole of carbon is equal to the number of atoms in a mole of boron is false.

Therefore, the correct answer is option c) the number of atoms in 1 mole of carbon = the number of atoms in 1 mole of boron.

The complete question is:

Which of the following is not true about one mole?

a) the mass of 1 mole of carbon atoms = the mass of

Answer:

3. V and T

Explanation:

For an ideal gas the volume and temperature remains directly proportional even if other conditions are constant.

This is the premise of the Charles's law.

Charles's law propounded by Jacques Charles found the relationship between the volume and temperature under constant pressure and predicted the absolute scale of temperature.

His law states that;

         "The volume of a fixed mass (mole) of a gas varies directly as its absolute temperature if the pressure is constant".

So;

                  V ∝ T (P, n constant)

In this stoichiometry problem, determine the percentage yield:

Excess aluminum metal reacts with aqueous nickel(II) sulfate to produce aqueous aluminum sulfate and nickel as a precipitate. In this reaction 108 g of aluminum were combined with 464 g of nickel(II) sulfate to produce 274 g of aluminum sulfate.

Answer:

80%

Explanation:

The correct equation for this reaction is;

2Al(s) + 3NiSO4(aq) --------> Al2(SO4)3 + 3Ni(s)

We already know that Al is in excess then NiSO4 is the limiting reactant.

Hence, Number of moles in 464 g of NiSO4 = mass/ molar mass

Molar mass of NiSO4 = 155 g/mol

Number of moles = 464g/155g/mol = 2.99 moles

Number of moles of Al2(SO4)3 = mass/molar mass

molar mass = 342 g/mol

So, Number of moles = 274g/342g/mol = 0.8 moles

Given the stoichiometric reaction equation;

3 moles of NiSO4 yields 1 mole of Al2(SO4)3

2.99 moles of NiSO4 yields 2.99 * 1/3 = 1 mole of Al2(SO4)3

percentage yield is given by; actual yield/ theoretical yield * 100/1

actual yield =  0.8 moles of Al2(SO4)3

Theoretical yield = 1 mole of Al2(SO4)3

Hence;

% yield = 0.8/1 * 100 = 80%

Our Sun will eventually turn into a red giant in the cooler temperature and high luminosity and in the white dwarf phase has a hot temperature & dim luminosity.

In astronomy, the Hertzsprung-Russell diagram, often known as the H-R diagram, is a graph that plots the absolute magnitudes (intrinsic brightness) of stars against their spectral classifications (temperatures).

From the given diagram it is clear that when sun turns into a red giant then the temperature decreases and luminosity increases as it becomes large in size. And when it finally become a white dwarf then temperature comparatively increases and luminosity gets dim due to smaller size.

Hence in the red giant phase sun has a cooler temperature and high luminosity and in the white dwarf phase has a hot temperature & dim luminosity.

This expression is typical of nuclear reactions. To balance this expression we must conserved the mass number and the atomic number.

The mass number is the superscripts and the atomic number is the subscript;

 Now;

 conserving mass number:

             27 + b  = 24 + 4

             27 + b  = 28  

                   b  = 28 - 27  = 1
