Question

There are 4 moles of methane burned to produce how many moles of water? CH4+2O2=CO2+2H2O

Answer 1

8 moles of water

Step-by-step explanation

The major products formed when an organic compound undergo combustion reaction are water and carbon dioxide

Below is the combustion formula

`\text{ C}_xH_y\text{ + x + }(y)/(4)O_2\text{ }\rightarrow\text{ xCO}_2\text{ + }(y)/(2)H_2O`

In the question above, 4 moles of methane reacts with oxygen

`\begin{gathered} \text{ 4CH}_4\text{ + 4+}(16)/(4)O_2\text{ }\rightarrow\text{ 4CO}_2\text{ + }(16)/(2)H_2O \\ \\ \text{ 4CH}_(4(g))\text{ + 8O}_(2(g))\text{ }\rightarrow\text{ 4CO}_(2(g))\text{ + 8H}_2O(l) \end{gathered}`

Therefore, 4 moles of methane will give 8 moles of water
