<u>Answer:</u> The chemical equation for the given reaction is given below.
<u>Explanation:</u>
When solid calcium oxide reacts with sulfur trioxide gas to produce solid calcium sulfate, the chemical equation follows:

This is the reaction when a metal oxide reacts with non-metal oxide to produce a salt.
By Stoichiometry of the reaction:
1 mole of solid calcium oxide reacts with 1 mole of sulfur trioxide gas to produce 1 mole of solid calcium sulfate.

Answer:
-Determination - in this stage, people have make commitment to change the bad habit as soon as possible. it is stage of planning.
Explanation:
There are six stages of change that have a unique role in changing one's behavior. The stages are:
-Pre-contemplation - in this stage people are more aware of this bad habit but at the same time they are not considering as a problem
- contemplation - At this stage, people are more serious about their bad habit and now are thinking of changing
-Determination - in this stage, people have made a commitment to change the bad habit as soon as possible. it is stage of planning.
- Action - at this stage of change people are taking a serious step toward changing their behavior
- Maintenance - in this stage people are avoiding all those criteria and source through which there is a chance to return back to bad habits
-Relapse - at this stage people do resumption of old behavior
The percent yield of carbon dioxide will be 49.0 %.
<h3>Percent yield</h3>
First, let's look at the equation of the reaction:

The mole ratio of octane to oxygen is 2:25.
Mole of 3.43 g octane = 3.43/114.23 = 0.03 mol
Mole of 19.1 g oxygen = 19.1/32 = 0.60 mol
Thus, octane is limiting.
Mole ratio of octane to carbon dioxide = 2:16.
Equivalent mole of carbon dioxide = 0.03 x 8 = 0.24 mol
Mass of 0.24 mol carbon dioxide = 0.24 x 44.01 = 10.5624 grams
Percent yield of carbon dioxide = 5.18/10.5624 = 49.0 %
