Write the complete balanced equation for the following reaction: c7h14 o2 yields co2 h2o
2 answers:
<u>Answer:</u> The balanced chemical equation is written below.
<u>Explanation:</u>
Balanced chemical equation is defined as the equation in which total number of individual atoms on the reactant side will be equal to the total number of individual atoms on the product side. These equations follow law of conservation of mass.
The chemical equation for the combustion of heptane follows:
By Stoichiometry of the reaction:
2 moles of heptane reacts with 21 moles of oxygen gas to produce 14 moles of carbon dioxide gas and 7 moles of water molecule.
Hence, the balanced chemical equation is written above.

Answer: Correct options are as follows.
- salt is not chemically bonded to water.
- salt and water retain their own chemical properties.
Explanation:
When salt is dissolved in water then it means that it is a physical change as salt has completely dissociated into ions but they are not chemically combined to the water molecules.
As a result, both salt and water will retain their chemical properties.
For example, NaCl when dissolved in water will dissociate as follows.
Only the particles of salt have evenly distributed in water.
And, when a components of a salt chemically combine with another substance then it will form a new compound.
Therefore, we can conclude that salt dissolved in water is a solution, therefore:
- salt is not chemically bonded to water.
- salt and water retain their own chemical properties.
