Read the chemical equation. 2H2 + O2 → 2H2O

Which of the following statements would be correct if one mole of hydrogen was used in this reaction? (5 points)

a
One mole of oxygen was used in this reaction.

b
Two moles of oxygen were used in this reaction.

c
One mole of water was produced from this reaction.

d
Two moles of water were produced from this reaction.

The correct answer is two moles of water were produced from this reaction.

Explanation:

2h2+02gives2h20

here,

2 mole of hyroden reacts with 1 mole of oxygen to give 2 mole of h20 gas at 22.4 ltr at ntp.

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm
