Question

In which of the following chemical equations,

the abbreviations represent the correct states of

the reactants and products involved at reaction

temperature?

(a) 2 2 H I O I HOg 22 2 () () ( ) + $ (b) 2 2 H g O I HOI 22 2 ( ) () () + $ (c) 2 2 H g O g HOI 22 2 ( ) ( ) () + $ (d) 2 2 H g O g HOg​

Answer 1

Answer:

$\sf {Correct \: Option \: Is \: ( C )}$

Because, reaction as during formation of water both hydrogen and oxygen are in gaseous form and produces water in liquid form.

So, the reactants involved at reaction temperature of 2H2(g)+O2(g)→2H2O

Answer 2

The reactants and products involved at reaction temperature $2H_{2}(g)+O_{2}(g)$→$2H_{2}O(I)$.

Explanation:

$2H_{2}(g)+O_{2}(g)$→$2H_{2}O(I)$ is the correction reaction as during formation of water both hydrogen oxygen are in gaseous form and produces water in liquid form. The abbreviations represent the correct states of the reactants and products involved at reaction.
