How much co2 (l) is produced when 2.10 kg of sodium bicarbonate reacts with excess hydrochloric acid at 25.0 °c and 1.23 atm? a)4.17 × 10-1 b)4.98 × 102 c)4.17 × 101 d)3.50 e)4.98 × 10-1

Answer : The correct option is, (B)

Explanation :

First we have to calculate the moles of .

Now we have to calculate the moles of .

The balanced chemical reaction will be,

From the balanced chemical reaction, we conclude that

As, 1 mole of react to give 1 mole of

So, 25 mole of react to give 25 mole of

Now we have to calculate the volume of .

Using ideal gas equation,

where,

P = pressure of gas = 1.23 atm

V = volume of gas = ?

T = temperature of gas =

n = number of moles of gas = 25 moles

R = gas constant = 0.0821 L.atm/mole.K

Now put all the given values in the ideal gas equation, we get

Therefore, the volume of carbon dioxide gas produced is,

2b2t

explanation:

2b2t
