Consider the N₂ gas produced:

Pressure, P = 1.2 atm

Volume, V = 16 L

Gas constant, R = 0.08206 L atm / (mol K)

Temperature, T = (273 + 23) K = 296 K

Gas law: PV = nRT

Then, n = PV/(RT)

No. of moles of N₂, n

= 1.2 × 16 / (0.08206 × 300)

= 0.79 mol

According to the given equation, mole ratio Cl₂ :

N₂ = 3 : 1

No. of moles of Cl₂ needed 

= (0.79 mol) × 3

= 2.37 mol

Mass of Cl₂ needed 

= (2.37 mol) × (35.5 × 2 g/mol) 

= 168 g

The amount of nickel that would be electroplated by passing a constant current of 7.2 A through a solution of NiSO₄ for 90 min is 11.83g.

Equivalent mass of any substance will be electroplated by 96485 coloumb of charge.

Equivalent mass of Ni in NiSO₄ = 58.7/2 = 29.35g

So that 96485 coloumb of charge = deposited 29.35g of Ni

Also charge will be calculated by usimg the below equation as:

Q = (I)(t), where

I = current = 7.2 ampere

t = time = 90 min = 5400 sec

Q = (7.2)(5400) = 38,880 coloumb

By using both the equations of coloumb, we calculate the grams of Ni electroplated by 38,880 coloumb charge as:

Mass of Ni = (29.35g)(38,880/96,485)

Mass = 11.826 grams = 11.83g

Hence required mass of nickle is 11.83 grams.

Answer:

7.5mols of S

Explanation:

just make sure your equation is balanced, and in this case it's balanced,

so now you can do more to more ratio.

so in this case we are dealing with SO2 and S.

According to our balanced equation we have 1 mol of SO2 producing 3mols of S, i.e

1mol(SO2). : 3mols(S)

we've been asked that if we use 2.5 moles of SO2, how many moles of S will be produced?

So, this is how we can determine the number of moles of S that will be produced .

SO2 : S

1mol : 3mols(S)

2.5mols: x

we cross multiply

x=2.5×3

x=7.5mols of S.

.: if we use 2.5 mols of SO2,, 7.5mols of Sulfur will be produced

Rate will double

Explanation:

Since the concentration of A is doubling the rate of reaction will also double, since in this scenario concentration is proportional to rate of reaction. So if the concentration of A were to triple the rate of reaction would also triple.

Answer:

1.48×10²⁴ Cu atoms

Explanation:

For this question you need to use Avogadro's number 6.022×10²³atoms.

2.45 moles of Cu ×[tex]\frac{6.022x10x^{23} atoms }{1 mole}[/tex]= 1.47539×10²⁴ atoms.

The moles cancel out so you are left with atoms.

Since there are 3 significant figures in the question there should be 3 significant figures in your answer, which is 1.48×10²⁴ Cu atoms.

17.93 grams of oxygen gas occupy 12.3L of space at 109.4 kPa and 15.4°C. Details about how to calculate mass can be found below.

The mass of a given gas can be calculated by multiplying the number of moles of the substance by its molar mass.

However, the number of moles of the gas must be calculated first as follows:

PV = nRT

Where;

1.079 × 12.3 = n × 0.0821 × 288.4

13.27 = 23.68n

n = 13.27/23.68

n = 0.56mol

Mass = 0.56 × 32

mass of oxygen gas = 17.93g

Therefore, 17.93 grams of oxygen gas occupy 12.3L of space at 109.4 kPa and 15.4°C.

Assuming the quantity of current passing through the zinc and copper electrolytes is the same, mass of Zinc deposited is (x/64) × 65.0 g.

Electrolysis is the decomposition of a substance known as an electrolyte when electric current is passed through its solution or molten form.

The mass of an electrolyte deposited when current is passed is dependent on the current and the charge on the ion.

In the electrolysis of copper and zinc, assuming the quantity of current passed through their solution are the same, the moles of each zinc and copper deposited will be the same since the charges on their ions are the same.

Assuming x g of copper is deposited.

molar mass of copper = 64.0 g

molar mass of Zinc = 65.0 g

moles of copper deposited = x/64

moles of zinc deposited = x/64

mass of Zinc deposited = (x/64) × 65.0 g

Therefore, the mass of Zinc deposited is (x/64) × 65.0 g.

The medium through which electromagnetic waves travel is called the electromagnetic field.

Answer: 2.36 moles

Explanation:

Using 1 g/mol for the atomic mass of hydrogen and 16 g/mol for the atomic mass of oxygen, we get that the gram-formula mass of water is 1(2)+16=18 g/mol. Thus, 42.5 grams of water is the same as 2.36 moles.

From the reaction, we know that for every 2 moles of water produced, 2 moles of dihydridotin are consumed. In each mole of dihydridotin, there is 1 mole of hydrogen, meaning that 2 moles of hydrogen are consumed.

Thus, the answer is 2.36 moles.
