Answer:

See below.

Explanation:

2Nacl+2Agno3 =2Agcl +2Nano3

or you could just write it as

Nacl+Agno3 =Agcl +Nano3

There is no real need of the 2's.

which type of chemical reaction occurs faster at equilibrium the formation of production from reactants or that of reactants fro

Degger [83]

Answer :-

None of the forward reaction or backward reaction will be faster at equilibrium as

definition of equilibrium is that phase in which the rate of formation of product from reactant and rate formation of reactant from product is equal

and hence , both will be form at equal rate !!

As a scuba diver descends under water, the pressure increases. At a total air pressure of 2.71 atm and a temperature of 25.0 C,

Answer:

The molar solubility of nitrogen gas is $1.32\times 10^{-3}mol/L$ .

Explanation:

Henry's law states that the amount of gas dissolved or molar solubility of gas is directly proportional to the partial pressure of the liquid.

To calculate the molar solubility, we use the equation given by Henry's law, which is:

$C_{N_2}=K_H\times p_{liquid}$

where,

$K_H$ = Henry's constant = $6.26\times 10^{-4}mol/L.atm$

$p_{N_2}$ = partial pressure of nitrogen gas

Total air pressure = P = 2.71 atm

Percentage of nitrogen in air = 78.09%

Mole fraction of nitrogen , $\hi_{N_2}= 0.7809$

$p_{N_2}=P\times \chi_{N_2}=2.71 atm\times 0.7809$

Putting values in above equation, we get:

$C_{N_2}=6.26\times 10^{-4}mol/L.atm\times 2.71 atm\times 0.7809\\\\C_{N_2}=1.32\times 10^{-3}mol/L$

Hence, the molar solubility of nitrogen gas is $1.32\times 10^{-3}mol/L$ .
