Gaseous vapor observed when handling dry ice (solid co_2 2 ) physical or chemical

Nadya [2.5K]

<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>

what is the differential rate expression of the change in B with time? Incorporate elements that describe both its formation and

Ivanshal [37]

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.

Hydrocarbons, compounds containing only carbon and hydrogen, are important in fuels.The heat of combustion of cyclopentane, C5H1

shtirl [24]

Answer : The balanced equation for the complete combustion of cyclopentane will be :

$2C_5H_{10}+15O_2\rightarrow 10CO_2+10H_2O$

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 :

$\text{Hydrocarbon}+O_2\rightarrow CO_2+H_2O$

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 :

$\text{Hydrocarbon}+O_2\text{(limited)}\rightarrow CO+CO_2+H_2O$

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 :

$2C_5H_{10}+15O_2\rightarrow 10CO_2+10H_2O$
