<u>Answer:</u> The reaction is known as combustion reaction.
<u>Explanation:</u>
Combustion reaction is defined as the reaction in which a hydrocarbon reacts with oxygen molecule to produce carbon dioxide gas and water molecule.
For Example: The chemical equation representing the combustion of methane gas follows:
By Stoichiometry of the reaction:
1 mole of methane gas reacts with 2 moles of oxygen gas to produce 1 mole of carbon dioxide gas, 2 moles of water with the release of heat.
Hence, the reaction is known as combustion reaction.

Internal resistance
(a). We need to calculate the current
Using rule of loop
Where, E = emf
R = resistance
r = internal resistance
Put the value into the formula
(b). We need to calculate the terminal voltage
Using formula of terminal voltage
Where, V = terminal voltage
I = current
r = internal resistance
Put the value into the formula
(c). We need to calculate the ratio of the terminal voltage of voltmeter equal to emf
Hence, This is the required solution.
