Chapter 19, Problem 19.71SP

Interpretation Introduction

Interpretation:

Find the mass change in grams accompanying the formation of $1mol$ of $CO$ and $1mol$ of $H_2$ in water-gas reaction.

$C\left(s\right) + H_{2}O\left(g\right) \to CO\left(g\right) + H_2\left(g\right) \Delta H^{\circ }=+131 kJ$

Concept Introduction: The change in mass during a chemical reaction or a nuclear reaction can be calculated using Einstein’s equation, given as

$\Delta E=\Delta m{c}^2$

Where, $\Delta m$ =change in mass

$c=3.00\times {10}^{8}m/s$
