Draw both the chair and boat conformation of 1,4-dimethylcyclohexane with the methyl groups as cis and trans for both conformations. Label your molecules for cis and trans. Tell which is the highest in energy.

Answer:

V₁ = 0.019 L

Explanation:

Given data:

Molarity of stock solution = 10.0 M

Volume of stock solution = ?

Molarity of CaCl₂ = 0.25 M

Volume of CaCl₂ = 0.75 L

Solution:

Formula:

V₁ = M₂V₂ / M₁

V₁ = 0.25 M × 0.75 L / 10.0 M

V₁ = 0.1875 M.L / 10.0 M

V₁ = 0.019 L

Answer:

1-Ecologists call this one-way flow of matter and energy from a producer to a primary, then to secondary, and perhaps to a tertiary consumer, a food chain. The food web shows all the organisms at each feeding level or trophic level.

2-Energy flows through an ecosystem in one direction: from producer to primary consumer to secondary consumer to higher consumers. A biomass pyramid provides a picture of the feeding and energy relationships within a food web and the direction of the flow of energy.

Reflection

Explanation:

The light from Earth's surface, reflected back towards the Moon, can illuminate it all the same. This is why, when the Moon is in a crescent phase, you can still see features on the dark portion of the Moon: we call this reflected, illuminating light the phenomenon of Earthshine.

Explanation:

Tidal range is the difference of the mean high tide level and the mean low tide level.

=> Tide range = 0.66m - (-0.55m) = 1.21m.

Answer:

Tidal Change=0.66-(-0.55)=0.66+0.55 = 1.21 meters

Explanation:

Tidal Change is the change in the mean high tide level and mean low tide level.

Tidal Change(m) =High tide level(m) - Low tide level(m)

Explanation:

The average atomic mass will be 3.70 amu

We have to obtain the average atomic mass by multiplying the mass of each isotope in amu by the relative abundance of the given isotope as contained in the data of the question.

Hence;

Average atomic mass;

(0.30 * 4) + (0.20 * 5) + (0.50 * 3)

= 1.20 + 1.00 + 1.50

= 3.70 amu

Answer:

1. There most not be rotation within the molecule.

2. Two non identical group must be present in the double bonded carbon atom.

Explanation:

This is because cis/ trans isomerism are that exhibit different structural configurations where the atoms are spartially arranged. They are also refered to as geometric isomers. They cannot be interconverted at room temperature because it requires the bonds to be broken and restructured.

Cis shows that the functional groups on present in the same side which trans isomerism show that the functional groups are on opposite sides.

Answer:

Matter can change from one state to another if heated or cooled. If ice (a solid) is heated it changes to water (a liquid). This change is called MELTING. If water is heated, it changes to steam (a gas).

Explanation:

Answer:

Fractional distillation is a method for separating liquids with different boiling points. For example, liquid ethanol can be separated from a mixture of ethanol and water by fractional distillation. ... The boiling point of ethanol is 78°C and the boiling point of water is 100°C.

Answer:

[tex]H_2(g)+O_2(g)\rightarrow H_2O_2(g)[/tex]

Explanation:

Hello!

In this case, since the formation reaction of a compound is undergone when the pure elements composing it are combined, for gaseous hydrogen peroxide, gaseous diatomic hydrogen and oxygen (standard state) must be combined in order to obtain the gaseous hydrogen peroxide as shown below:

[tex]H_2(g)+O_2(g)\rightarrow H_2O_2(g)[/tex]

Whereas it is proved there are two hydrogen and oxygen atoms at each side of the chemical equation and therefore it is balanced.

Answer:

The volume of the gas increases as the temperature increases.

Explanation:

Gas volume does increase with increasing temperature providing that the pressure remains constant. Temperature and pressure both interact with the gas volume according to the gas Laws and both variables must be accounted for at the same time.

Answer:  The mass of 405 mL of ethylene glycol is 444.3 g.

Explanation:

Density is defined as the mass contained per unit volume.

[tex]Density=\frac{mass}{Volume}[/tex]

Given :

Density of the ethylene glycol= [tex]1097g/L[/tex]

Volume of the ethylene glycol= [tex]405ml[/tex]  = 0.405 L   (1L=1000ml)

Mass of  the ethylene glycol = ?

Putting in the values we get:

[tex]1097g/L=\frac{x}{0.405L}[/tex]

[tex]x=444.3g[/tex]

Thus the mass of 405 mL of ethylene glycol is 444.3 g

Answer:

12

Explanation:

4x3 is 12

Answer:

To solve this simple expression you must substitute [tex]a[/tex] for the number you are given, so, 3.

4[tex]a[/tex] -> 4 3

Now, when numbers are next to each other like this, they are always multiplied. So, the find the answer you would multiply 4 times 3...

4 x 3 = 12

So, you answer will be 12!

Answer: The salinity of ocean water is 34 ppt.

Explanation:

Salinity is defined as the number of grams of salts present per kilogram of seawater. It is expressed in parts per thousand.

The formula used to calculate the salinity of ocean water or sea water is:

[tex]\text{ Parts per thousand}=\frac{\text{Mass of salts}}{\text{Mass of sea water}}\times 1000[/tex]

We are given:

Mass of salts = 17 g

Mass of sea water = 500 g

Putting values in above equation, we get:

[tex]\text{ Parts per thousand}=\frac{17g}{500g}\times 1000\\\\\text{ Parts per thousand}=34[/tex]

Hence, the salinity of ocean water is 34 ppt.

compressions

Explanation:

in a longitudinal wave, particles of the medium vibrate in a direction that is parallel to the direction that the wave travels. places where particles of the medium crowd closer together are called compressions. places where particles of the medium spread farther apart are called rarefactions

The region of a longitudinal wave where particles are closest together is a Compression. A further explanation is below.

The process of re-encoding knowledge such that it consumes fewer bits of information than the original information.

Compression has been frequently sometimes used speed things up the transportation of data such as words as well as visual graphics, and even to reduce the amount of memory required to retain such content.

Answer:

The Earth’s greenhouse effect is a natural consequence of the chemical makeup of its atmosphere. If it

were not for the greenhouse effect, life as we know it could not exist on Earth: it would be too cold. Our

atmosphere is made mostly of nitrogen and oxygen, but also contains several other gases. These include

carbon dioxide, methane, nitrous oxide, water vapor and ozone, which are known as greenhouse gases.

Greenhouse gases are released naturally through geologic processes and the metabolic activity of living

things. However, there is an ongoing debate over human effects on Earth’s global climate. Human industrial activity on the planet has increased the quantities of greenhouse gases through agriculture, manufacturing, power generation, and engines used for transportation. Key questions include: Is the average temperature of Earth increasing? Does the presence of human beings contribute to global warming? If the temperature of Earth does become warmer, how will it affect us?

1. Oceans -> Atmosphere = Evaporation

2. Atmosphere -> Clouds = Condensation

3. Cloud -> Snow = Freezing

4. Glacier -> River = Melting

5. Cloud -> Soil = Precipitation

Explanation

1. When liquid water is heated by the sun it evaporates into the atmosphere

2. When the saturated air cools down in the atmosphere, Water vapor condenses into tiny droplets to form a cloud

3. When the Temp is below freezing, water droplets crystalize into snow flakes.

4. Glaciers melt into the River

5. The cloud precips into soil
