A student collects 629ml of oxygen at 0.500at, the student collected 0.0337 moles. At what temperature did the student collect t
VashaNatasha [74]

Answer:

114 K

Explanation:

Given data

  • Volume of oxygen (V): 629 mL = 0.629 L
  • Pressure of oxygen (P): 0.500 atm
  • Moles of oxygen (n): 0.0337 mol
  • Temperature (T): ?

We can calculate the temperature at which the student collected the oxygen using the ideal gas equation.

P \times V = n \times R \times T\\T = \frac{P \times V}{n \times R}  = \frac{0.500atm \times 0.629L}{0.0337mol \times 0.0821atm.L/mol.K} = 114 K

The oxygen gas was collected at 114 K.

If 13.7 grams of manganese oxide reacts with excess hydrogen chloride gas, how many grams of water are formed?
Lerok [7]

Answer:

5.67 g OF WATER WILL BE FORMED WHEN 13.7 g OF MnO2 REACTS WITH HCl GAS.

Explanation:

EQUATION FOR THE REACTION

Mn02 + 4HCl --------> MnCl2 + Cl2 + 2H2O

From the balanced reaction between manganese oxide and hydrogen chloride gas;

1 mole of MnO2 reacts to form 2 mole of water

At STP, the molecular mass of the sample is equal to the mole of the substance. So therefore:

(55 + 16 * 2) g of MnO2 reacts to form 2 * ( 1 *2 + 16) g of water

(55 + 32) g of MnO2 reacts to form 2 * 18 g of water

87 g of MnO2 reacts to form 36 g of water

If 13.7 g of MnO2 were to be used?

87 g of MnO2 = 36 g of H2O

13.7 g of MnO2 = ( 13.7 * 36 / 87) g of water

= 493.2 / 87 g of water

Mass of water = 5.669 g of water

Approximately 5.67 g of water will be formed when 13.7 g of manganese oxide reacts with excess hydrogen chloride gas.
