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.

Hello there!
In this case, since the radioactive decay kinetic model is based on the first-order kinetics whose integrated rate law is:
We can firstly calculate the rate constant given the half-life as shown below:
Therefore, we can next plug in the rate constant, elapsed time and initial mass of the radioactive to obtain:
