There are 3 moles of water formed in the complete combustion of ethane.
<h3>What is Combustion Reaction? </h3>
Combustion is a chemical reaction between substances , usually including oxygen and usually accompanied by the generation of heat and light in form of flame.
For example , the wood burning in a fireplace. The wood is a fuel which continuously react with oxygen in the air in a combustion reaction.
When ethane goes for combustion
reaction ,
C2H6+7/2 O2→2CO2+ 3H2O
As you can see on the above reaction 3 moles of water molecules are produced .

A solution means that you're trying to solve (or deal) with a situation.
For example, if you're having trouble trying to solve a math problem, that means that you're trying to figure out that problem.
Answer: 30.27 g
Explanation:
Since the silver is in units of atoms, we have to use Avogadro's number and molar mass.
Avogadro's number: 6.022×10²³ atoms/mol
Molar Mass: 107.87 g/mol
Now that we have everything we need, we can convert atoms to grams.
The answer is <span>increasing the surface area of Fe(s) and increasing the concentration of HCl(aq).
the rate of reaction can be increased if the interaction between the reactants in better. by increasing the surface area of a solid, such as Fe, you make more possible each molecule of Fe to interact with HCl. Also, by increasing the concentration of HCl, it mean there is more molecule of HCl to interact with Fe.</span>
