2) </span><span>Nuclear waste disposal capability is an environmental imperative, so their environment would be polluted by very radioactive materials.

When aluminum is placed in concentrated hydrochloric acid, hydrogen gas is produced. 2 Al ( s ) + 6 HCl ( aq ) ⟶ 2 AlCl 3 ( aq )
Dovator [93]

Answer:

The volume of hydrogen gas produced at STP is 4.90 liters.

Explanation:

2Al (s) + 6 HCl (aq)\rightarrow 2 AlCl_3 (aq) + 3 H_2 (g)

Moles of aluminium =\frac{3.60 g}{27 g/mol}=0.1333 mol

According to reaction , 2 moles of aluminium gives 3 moles of hydrogen gas.

Then 0.1333 moles of aluminium will give:

\frac{3}{2}\times 0.1333 mol=0.2 moles of hydrogen gas

Volume of 0.2 moles of hydrogen gas at STP = V

Temperature at STP = T = 298.15 K

Pressure at STP = P = 1 atm

n = 0.2 mol

PV = nRT (Ideal gas equation)

V=\frac{nRT}{P}=\frac{0.2mol\times 0.0821 atm L/mol K\times 298.15 K}{1 atm}=4.8956 L\approx 4.90 L

The volume of hydrogen gas produced at STP is 4.90 liters.

A drum used to transport crude oil has a volume of 162 L. How many grams of water, as steam, are required to fill the drum at 1.
Paraphin [41]

Answer:

114.48g

Explanation:

Step 1:

Data obtained from the question:

Volume (V) = 162 L

Pressure (P) = 1.20 atm

Temperature = 100°C = 100°C+ 273 = 373K

Number of mole (n) of H2O =?

Recall:

Gas constant (R) = 0.082atm.L/Kmol

Step 2:

Determination of the number of mole of H2O i.e steam.

Using the ideal gas equation, the number of mole of H2O can be obtained as follow:

PV = nRT

1.2x 162 = n x 0.082 x 373

Divide both side by 0.082 x 373

n = (1.2x 162) /(0.082 x 373)

n = 6.36 moles

Step 3:

Determination of mass of H2O i.e steam:

This is illustrated below:

Molar Mass of H2O = (2x1) + 16 = 2 + 16 = 18g/mol

Number of mole H2O = 6.36 moles

Mass of H2O =?

Mass = number of mole x molar Mass

Mass of H2O = 6.36 x 18

Mass of H2O = 114.48g

Therefore, the mass of H2O i.e steam required to fill the drum of crude oil is 114.48g
