Answer: 25 moles of water are produced.

Explanation:

Combustion is a type of chemical reaction in which fuel is reacted with oxygen to form carbon dioxide and water.

Example:  

CH_4+2O_2 \rightarrow CO_2+2H_2O

According to stoichiometry:

1 mole of methane on combustion produces= 2 moles of water

12.5 moles of methane on combustion produces= \frac{2}{1}\times 12.5=25 moles of water

Thus 25 moles of water are produced from the combustion of 12.5 moles of methane.

If density usually increases with decreasing temperature, why does ice float on liquid water? Explain.
zepelin [54]

Answer:

If you continue to cool water past 4 degrees Celsius, its density starts to plummet (you can see this in the graph). At zero degrees, i.e., the temperature at which water turns into ice, the density of water is actually quite low. It turns out that ice has a lower density than water, and any object that has a lower density than the liquid form on which it’s kept (in this case, water) will be able to float!
