why is the concentration of helium increased in some gas mixtures that divers breath in order to reduce the partial pressure of

sdas [7]

Answer:

Because of oxygen toxicity.

Explanation:

Oxygen toxicity.

Oxygen has been known to cause central nervous system (CNS) toxicity when the pressure gets higher. This toxicity can cause convulsions, and this can cause the diver to drown.

The current standard maximum safe oxygen working pressure is 1.4 atm ppO2. This is equal to 56.5m/185′ when breathing air (21% O2 / 79% N). Below that depth the fraction of oxygen in a breathing gas must be reduced, and in order to maintain this maximum pressure of 1.4 ppO2, Helium must be added.

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 :

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