What is the molar mass of an unknown gas with a density of 14.1 g/L at 4.00 atm and 35.0 °C?​

Answers

89.08 g/mol is the molar mass of an unknown gas with a density of 14.1 g/L at 4.00 atm and 35.0 °C.

We know that

PV=nRT.

where,

P = Pressure of the gas

V = Volume of the gas

n = Mole

Mole = Given mass/Molar mass

= m /Mw

R = Real gas constant = .08205 L atm/mole k

T = temperature

Now,

PV = mRT/Mw

Mw= mRT/PV. ( m/V=density)

Mw = dRT/P

Mw = 14.1 g/L × 0.08205 × 308/4

Mw = 89.08 g/mol

Hence we can say that Molar mass is 89.08 g/mol.

8. Interestingly, the 1s orbital in the chlorine atom encloses more volume of space than the 1s orbital in an argon atom. Explain.

Answers

Answer: Chorine's atomic radius in larger than that of Argon.

Explanation: Thinking in terms of atomic radius, as you move from left to right on the periodic table, atomic radius decreases. However, as you move from top to bottom on the periodic table, the atomic radius increases. This is because when you are moving from top to bottom on the periodic table, more orbitals are added. When you move from left to right, the number of orbitals remains the same but the number of protons in the nucleus is still increasing. They have a stronger hold on the electrons and pull them closer. This also makes it harder for outside photons to remove an electron from an atom (ionization energy) as you move from left to right on the periodic table.

Now let's think about chlorine and argon. They are right next to each other in the upper right-hand corner of the periodic table. However, chlorine does come first and if we think back to the atomic radius, it gets smaller as you move from left to right. Chlorine comes before Argon when looking left to right.

In conclusion, chorine's atomic radius is larger than that of argon.

Here the substance is water. So, we need to know the value of specific heat capacity of water to solve this question.

The specific heat capacity of water is 4.18 J/g° C.

This is the heat required to increase the temperature by one degree Celsius. To increase the temperature by 20 degree C, the heat required will be 2 times of 4.18 J/g° C.

The heat required to raise the temperature of n grams of a substance by m0C will be,

Let us rewrite the equation as,

q = mc Δ t

Where q is the heat required, m is the mass of the substance, c is the specific heat capacity of the substance and Δ t is the temperature difference.

Given that,

m = 200g

Δ t = 55° C – 35° C = 20° C

c = 4.18 J/g° C

Let us substitute the values:

q = 200*4.18*20

Hence the heat required is 16720J.

Converting it to kJ, the heat required to raise the temperature of 200 grams of water from 55° C to 35° C is 167 KJ.

When we measure the temperature change of the calorimeter, we may use this equation to compute the heat released by a sample because the calorimeter is an instrument for which we are aware of (or can ascertain) its heat capacity.

When a liquid absorbs or loses energy, the temperature of the liquid varies.

In accordance with the formula

Q= mCΔT

m = 200g

ΔT = 550 - 35

ΔT = 515

C = 4.182 J/kg °C

Q is equal to 200 * 4182 * 515

Q = 430746 Joules.

Water has a 4,200 J/kg°C (joules per kilogram per degree Celsius) specific heat capacity. This indicates that 4,200 J are required to increase the temperature of 1 kilogram of water by 1°C.

This compound ( 2,3-dimethyl-2-heptene ) is symmetric or asymmetric

Answers

Answer:

symmetric

Explanation:

The compound 2,3-dimethyl-2-heptene is symmetric. A compound is symmetric if it has an identical molecular structure on both sides of its central axis. In the case of 2,3-dimethyl-2-heptene, the molecule has a central carbon atom with two methyl groups attached to it, one on the 2nd position and one on the 3rd position. Because the groups attached to the central carbon atom are identical, the molecule is symmetric.

In contrast, an asymmetric compound has a molecular structure that is different on each side of its central axis. For example, a compound with a central carbon atom attached to two different groups, such as a methyl group and a hydrogen atom, would be asymmetric.

Knowing what you know about photosynthesis, explain how the process may help reduce global warming.

Answers

Photosynthesis may help reduce global warming because the carbon dioxide is consumed during the process.

How photosynthesis may help reduce global warming

Global warming has to do with an increase in the average global temperature brought about by the increase in the concentration of greenhouse gases in the atmosphere.

The greenhouse gases form a layer that traps reflected solar radiation in the atmosphere. They prevent these radiations from returning back to space and consequently, the temperature of the planet keeps increasing. The more the concentration of these gases in the atmosphere, the more the warming increases.

Carbon dioxide gas represents a major component of greenhouse gases and has been the main culprit in global warming.

During photosynthesis, carbon dioxide is utilized by green plants to make carbohydrates. Thus, photosynthesis remains a major way through which the concentration of carbon dioxide in the atmosphere can be reduced and consequently reduce global warming.

Carbon dioxide gas, CO2, effuses at a rate that is 1.087 times the effusion rate of a second gas. One molecule of this second gas contains one atom of nitrogen and two other atoms that are identical. What element are these other atoms?

Answers

Ideal gas law is valid only for ideal gas not for vanderwaal gas. To solve such, we need to know the relation between rate of effusion and molar mass of gases. Therefore, the molar mass of unknown gas is 53.6g/mol.

What is ideal gas equation?

Ideal gas equation is the mathematical expression that relates pressure volume and temperature.

Mathematically the relation between rate of effusion of gases and their molar masses can be given as:

rate of effusion of unknown gas/rate of effusion of carbon dioxide gas=√molar mass of carbon dioxide/molar mass of particular gas

rate of effusion of carbon dioxide=1.087 ×rate of effusion of unknown gas

Substituting all the given values we get

rate of effusion of unknown gas÷ 1.087 ×rate of effusion of unknown gas=√44 g/mol÷ molar mass of unknown gas

1÷  1.087=√44 g/mol÷ molar mass of unknown gas

squaring both side

0.82=44 g/mol÷ molar mass of unknown gas

molar mass of unknown gas= 53.6g/mol

Therefore, the molar mass of unknown gas is 53.6g/mol
