Fill in the coefficients that will balance the following reaction:
Burka [1]

Answer:

a0 = 2

a1= 9

a2= 6

a3= 8

Explanation:

The equation for the reaction is;

C3H7OH + O2 → CO2 + H2O

To balance the chemical equation we introduce coefficients;

Therefore the balanced chemical equation will be;

2C3H7OH + 9O2 → 6CO2 + 8H2O

Chemical equations are balanced to ensure the law of conservation of mass is obeyed, such that the mass of the reactants is equivalent to that of the products.

In the first 85.0 s of this reaction, the concentration of no dropped from 1.12 m to 0.520 m . calculate the average rate of the
goldenfox [79]

In the first 85.0 s of this reaction, the concentration of no dropped from 1.12 m to 0.520 m .

What is rate of a reaction?

The speed at which a chemical reaction takes place is the rate of the reaction. It is the concentration change per unit time of a reactant in a reaction.

Since the concentration of NO reduces to half its initial concentration in 85 seconds that is from 1.12m to 0.520m, it can be said that 85 seconds is the half life interval for the reaction, <u>Hence on average, </u><u>half reaction</u><u> is completed in the time interval of </u><u>85 seconds</u><u>.</u>
