Q.10.105 - An Introduction to General, Organic, and Biological Chemistry

Question

Complete and balance each of the following

a. ${\mathrm{ZnCO}}_3\left(s\right)+{\mathrm{H}}_2{\mathrm{SO}}_4\left(aq\right)⟶$

b. $\mathrm{Al}\left(s\right)+\mathrm{HBr}\left(aq\right)⟶$

Step-by-Step Solution

Answer

Part (a). ${\mathrm{ZnCO}}_3\left(s\right)+{\mathrm{H}}_2{\mathrm{SO}}_4\left(aq\right)\to {\mathrm{ZnSO}}_4\left(aq\right)+{\mathrm{CO}}_2\left(g\right)+H_{2}O\left(l\right)$

Part (b). $2\mathrm{Al}\left(s\right)+6HBr\left(aq\right)\to 2\mathrm{AlBr}3\left(aq\right)+3{\mathrm{H}}_2\left(g\right)$

Step 1: Given Information (Part a)

A chemical reaction is a cycle that prompts the compound change of one bunch of substance substances to another. Classically, synthetic responses include changes that just include the places of electrons in the framing and breaking of compound connections between iotas, with no change to the cores (no change to the components present), and can frequently be depicted by a compound condition

Step 2: Explanation Part (a)

Balancing the equation,

${\mathrm{ZnCO}}_3\left(s\right)+{\mathrm{H}}_2{\mathrm{SO}}_4\left(aq\right)\to {\mathrm{ZnSO}}_4\left(aq\right)+{\mathrm{CO}}_2\left(g\right)+H_{2}O\left(l\right)$

Step 3: Explanation Part (b)

Balancing the equation,

$2\mathrm{Al}\left(s\right)+6HBr\left(aq\right)\to 2\mathrm{AlBr}3\left(aq\right)+3{\mathrm{H}}_2\left(g\right)$
