Answer 1

Answer:

c) 4 moles

Explanation:

$2h _{2} \: + o_{2} \: = 2h _{2} o$

10 gram of hydrogen = 10/2 = 5 moles

64 gram of oxygen = 64/32 = 2 moles

as per equation 1 mole of oxygen react with 2 mole of hydrogen

so to form 1 mole of water 1 mole of oxygen is required and 2 mole of hydrogen is required

there are only two mole of oxygen so 2 × 2 = 4 mole

4 mole of water (h2o) is produced
