Answer: 
Explanation:
Combustion is a chemical reaction in which hydrocarbons are burnt in the presence of oxygen to give carbon dioxide and water.
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products formed must be equal to the mass of reactants taken. In order to get the same mass on both sides, the atoms of each element must be balanced on both sides of the chemical equation.
The balanced combustion reaction is,:
Answer:
21.1cm or 10.1cm
Explanation:
Since the percent error is 35.5% and the experimental measurement was 15.6cm, the two possible values for the actual measurement are 15.6 plus 35.5% of 15.6 or 15.6 minus 35.5% of 15.6.
This is this:
15.6 + (0.355 x 15.6)
= 15.6 + 5.54
= 21.1cm
Or this:
15.6 - (0.355 x 15.6)
= 15.6 - 5.54
= 10.1cm
