[URGENT!] - Equilibrium Problem

Consider the following reaction:

4A + 2B ⇌ 2C + D (all gases at STP)

Initially, the reaction system is at equilibrium, with [A] = [B] = 2.60 M, and [C] = [D] = 3.10 M, making K = 0.0964. The reaction takes place in a 5.00-liter container. Moles of B are removed until the new equilibrium concentration of C is 2.70. How many moles of B were removed?

Answers

Answer 1

The equilibrium constant expression for this reaction is:

K = [C]2[D] / [A]4[B]2

We can rearrange this expression to solve for [B]:

[B] = √([A]4[C]2[D] / K)

Plugging in the given values, we get:

[B] = √((2.60 M)4(2.70 M)2(3.10 M) / 0.0964)

= √(6.76 M)

= 0.26 M

The initial concentration of B is 2.60 M, so the change in concentration of B is 2.60 M - 0.26 M = 2.34 M.

Since the reaction takes place in a 5.00-liter container, the number of moles of B that were removed is 2.34 M * 5.00 L = 11.7 moles.

Therefore, 11.7 moles of B were removed.

В.
an increase in the amount of minerals on Earth
C.
an increase in the amount of carbon dioxide in Earth's atmosphere
D
an increase in the amount of ozone in Earth's atmosphere

Answers

Answer:

C

Explanation:

trees (as well as other plants) produce carbon dioxide. deforestation is the removal of trees. this will not cause an increase in any pollutants such as ozone. ozone is made from VOCs and other harmful pollutants, and not caused by trees. tearing down trees will also not create more soil. So the answer has to be C

What is the coefficient of the scientific notation answer ? What is the exponent of the scientific notation answer ? How many significant figures are there in the answer ? What is the right most significant figure in the answer ?

Answers

Answer:

See explanation

Explanation:

We know that 1 mole of a gas occupies 22.4 L

Hence, 1.65 moles of nitrogen gas occupies 1.65 moles * 22.4 L/1 mole = 36.96 L or 3.696 * 10^1 L = 3.70 * 10^1 L

The exponent of the scientific notation answer = 1

The significant figures there are  in the answer = 4

The right most significant figure in the answer = 2

How many moles do I have of Lithium if I have 116.3g

Answers

Answer:

16.85mol

Explanation:

The number of moles of a substance can be calculated by dividing the mass of that substance by its molecular mass. That is;

number of moles (n) = mass (m) /molar mass (MM)

Molar mass of lithium = 6.9g/mol

Hence,

number of moles = 116.3 ÷ 6.9

Moles = 16.85mol

Therefore, 16.85moles is present in 116.3g of Li.

How does temperature differ from heat?

Answers

Answer:

Heat is a specific spectrum of the temperature scale while temperature is a lot broader

Explanation:

Indicate whether each statement is true or false. Drag the appropriate statements to their respective bins. the octet rule is based on the fact that filling in all s and p valence electrons in a shell gives eight electrons. compounds in which nitrogen is the central atom are frequent exceptions to the octet rule because they have too many electrons surrounding the nitrogen. boron compounds are frequent exceptions to the octet rule because they have too few electrons surrounding the boron. the si in sih4 does not follow the octet rule because hydrogen is in an unusual oxidation state.

Answers

Answer:

the octet rule is based on the fact that filling in all s and p valence electrons in a shell gives eight electrons--- True

boron compounds are frequent exceptions to the octet rule because they have too few electrons surrounding the boron......True

compounds in which nitrogen is the central atom are frequent exceptions to the octet rule because they have too many electrons surrounding the nitrogen...... false

the si in sih4 does not follow the octet rule because hydrogen is in an unusual oxidation state......false

Explanation:

The octet rule simply means that atoms tend to be stable when they have eight electrons in their outermost shell. This rule mostly applies to the s and p orbitals and not to the d and f orbitals. The sum of the total electrons in the outermost s and p orbitals is often equal to eight for an atom to be considered stable, for example, the noble gases.

Boron often forms compounds which has less than eight electrons around the boron central atom because the compounds of boron often have a sextet of electrons owing to the fact that boron is trivalent and forms mostly covalent compounds.

Nitrogen compounds mostly obey the octet rule and do not have excess electrons. The oxidation state of hydrogen in SiH4 is not unusual.

Describe what happens to the molecules in the ice as temperature of the ice increases

Answers

Answer:

When you heat ice, the individual molecules gain kinetic energy, but until the temperature reaches the melting point, they don't have energy to break the bonds that hold them in a crystal structure. They vibrate more quickly within their confines as you add heat, and the temperature of the ice goes up.

Answer:

As energy is transferred to the water molecules in the ice, the motion of the molecules increases. The motion of the molecules increases enough that it overcomes the attractions the water molecules have for each other causing the ice to melt.

A sample of gas is kept at a temperature of 300 k, a volume of 1.45L, and a pressure of 3.00 kPa. How many moles of has are in the sample

Answers

Answer:

the number of moles of the gas is 0.00174 mol.

Explanation:

Given;

temperature of the, T = 300 K

volume of the gas, V = 1.45 L

Pressure of the gas, P = 3.0 kPa

The number of moles of the gas is calculated using Ideal gas equation, as follows;

PV = nRT

Where;

n is number of moles of the gas

R is the ideal gas constant, = 8.315 L.kPa/mol.K

n = PV / RT

n = (3 x 1.45) / (8.315 x 300)

n = 0.00174 mol.

Therefore, the number of moles of the gas is 0.00174 mol.

Answers

Answer:

11.5 or 11.52, depending on however many decimal places you round it to

Explanation:

the equation for mass ( using the specific heat capacity equation) is energy transferred divided by temperature change x the specific heat capacity.

so, we do 725 ÷ 32° (the temp change) x 2.03 = 11.52 or 11.5, depending on how many decimal places you round to

i would round to 2 decimal places, so the answer would be 11.52kg.

mass is measured in kg :) hope this helped.

Explanation:

The temperature of 200 mL of gas originally at STP is changed to –25o C at constant volume. Calculate the final pressure of the gas in mmHg.

Answers

Answer:

691.6 mmHg

Explanation:

At standard temperature and pressure, temperature of a system = 273K, and pressure= 1atm

T1= 273.15K

P1= 1atm

T2= (–25°C +273.15 )= 248.15K

From Gay-Lussac's law which expressed that at constant volume, pressure of a particular mass of gas is directly proportional to temperature . It can be expressed as

P1 / T1 = P2 / T2

Where P1= initial pressure

T2= final temperature

T1= initial temperature

P2= final pressure

Making P2 subject of the formula

P2= (P1 × T2)/ P1

Substitute the values we have

P2= (1 atm × 248.15K)/273.15

P2= 0.91 atm

But

1atm= 760 mmHg

0.91 atm= X mmHg

If we cross multiply we have

X mmHg= (760× 0.91)/1

= 691.6 mmHg

Hence, the final pressure of the gas in mmHg is 691.6 mmHg
