Question

20.0 kg of H2 and 32 kg of O2 are reacted to produce H2O.the amount of H2O formed after completion of reaction is​

Answer 1

Answer:

Refer to above attachment.

Answer 2

Concept Introduction:-

Chemical reaction are the process in which a set of the chemical compounds is converted into another set of the chemical substances.

Given Information:-

We have been given that $20.0$ kg of $H_2$ and $32$ kg of $O_2$ are reacted to produce $H_2O$.

To Find:-

We have to find that the amount of $H_2O$ formed after completion of reaction is​

Solution:-

According to the problem

$2 \mathrm{H}_{2}+\mathrm{O}_{2} \longrightarrow 2 \mathrm{H}_{2} \mathrm{O}$

$=20000 \mathrm{gm} \quad 32000 \mathrm{gm}\\4 \mathrm{gm} \mathrm{H}_{2} \longrightarrow 32 \mathrm{gm} \mathrm{O}_2\mathrm{Igm} \mathrm{H} \mathrm{H}_{2} \longrightarrow 8 \mathrm{gm} \mathrm{O}$

$20000 \mathrm{gm} \mathrm{H} \longrightarrow 20000 \times 8 \mathrm{gmO}_{2}$

$=160000 \mathrm{gma}\\.\Rightarrow Oxygen \rightarrow$ limiting.

$32 \mathrm{gm} \mathrm{O} \longrightarrow 36 \mathrm{gm} \mathrm{} \mathrm{H}_{2} \mathrm{O}$

$1 \mathrm{gm} \mathrm{O} \longrightarrow \frac{36}{32} \mathrm{gm} \mathrm{} \mathrm{H}_{2} \mathrm{O}\\32000 \mathrm{gm} \mathrm{O} \rightarrow \frac{36}{32} \times 32000 \mathrm{gm} \mathrm{H}_{2} \mathrm{O}\\=\frac{360 \mathrm{gg} \times \mathrm{k}}{108 \mathrm{~kg}}\\=72 \mathrm{Kg} .36 \mathrm{~kg} (opHon -\mathrm{H})$

Final Answer:-

The amount of $H_2O$ formed after completion of reaction is​ $36$.
