Question

2H2(x) + O2(y) → 2H20 (z)Notice the x, y, and z in the subscripts. What symbols should replace x, y, and z?a. s,l,gb. g,g,sc. g,g,ld. l,l,g

Answer 1

the chemical reaction is as follows:

$2H_2(x)+O_2(y)\rightarrow2H_2O(z)$

Hydrogen is taken as gas, oxygen is also gas, and water is in liquid form.

Thus, x represents gas, y represents gas, and z represents liquid.

$\begin{gathered} x\rightarrow g \\ y\rightarrow g \\ z\rightarrow l \end{gathered}$

Thus, the correct option is (c).
