Chapter 10: Q.10.105 (page 360)

Complete and balance each of the following

a.ZnCO3(s)+H2SO4(aq)⟶

b.Al(s)+HBr⁡(aq)⟶

Short Answer

Expert verified

Part (a).ZnCO3(s)+H2SO4(aq)→ZnSO4(aq)+CO2(g)+H2O(l)

Part (b).2Al(s)+6HBr(aq)→2AlBr3(aq)+3H2(g)

Step by step solution

01

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

02

Explanation Part (a)

Balancing the equation,

ZnCO3(s)+H2SO4(aq)→ZnSO4(aq)+CO2(g)+H2O(l)
03

Explanation Part (b)

Balancing the equation,

2Al(s)+6HBr(aq)→2AlBr3(aq)+3H2(g)
