<span>Dry ice is frozen carbon dioxide. It is easy to assume that the fog surrounds dry ice is carbon dioxide returning to it's gaseous however, you can not see that process. The vapors you see is the water molecules in the air condensing as a result of the cooling or energy removal by the dry ice. When energy is removed from water molecules they become colder and move slower than water in a gaseous. Similar to clouds in the air, the water condenses into a form that you can see.</span>
Answer:
for a i think it is choice 2
for b i think it is the first choice
Explanation:
The differential rate expression for the rate of change in the concentration of B with time is
-rB = dCB/dt = kCB^n
where k is the rate constant and
n is the order of the reaction
This is assuming that the rate is only affected by the concentration of B and the order of the reaction is in the nth order.
Answer : The balanced equation for the complete combustion of cyclopentane will be :

Explanation :
As we know that the hydrocarbons can undergo complete or incomplete combustion that depends on the amount of oxygen available.
Complete combustion : It takes place when there is a good supply of oxygen. In this, hydrocarbon react with the oxygen to give carbon dioxide and water as a product.
The general reaction will be :

Incomplete combustion : It takes place when there is a poor supply of oxygen. In this, hydrocarbon react with the oxygen to give carbon monoxide, carbon dioxide and water as a product.
The general reaction will be :

As per question, the complete combustion of cyclopentane react with oxygen to gives carbon dioxide and water as a product.
Therefore, the balanced chemical reaction will be :
