Answer 1

Explanation:

Number of water molecules is 12.044×{10}23

1 mole of water contains 6.022×{10}23

molecules

2 moles contain 2×6.022×{10}23 molecules =12.044×{10}23

Answer 2

Answer: CH4 + 2O2---> CO2 + 2H2O. In this equation there are 2 moles of water molecules.

Explanation:

CH4 + 2O2---> CO2 + 2H2O

In this equation methane reacts with 2 moles of oxygen gives carbondioxide and 2 moles of water  along with heat and light . This reaction is redox reaction because in this reaction carbon is getting reduced and hydrogen is getting oxidised.

Redox reaction : Redox reaction can be defined as those reactions in which oxidation and reduction  takes place simultaneously . It is also called oxidation reduction reaction as one substance gets oxidised and one substance gets reduced.
