Question

Cu+Zn =?H2CO3=?H2O+CaO=?Cr+HBr=?CaO+CO2

Answer 1

1)реакция не идет. 2) Н2СО3-->Н2О+СО2. 3)Н2О+СаО->Са(ОН)2. 4) X. 5) CaO+CO2-> CaCO3

Answer 2

Cu + Zn = ? H2CO3 = ? H2O + CaO = ? Cr + HBr = ? CaO + CO2

Let's break down each equation and find the products:

1. Cu + Zn: - The reaction between copper (Cu) and zinc (Zn) is a single replacement reaction. - The copper will replace the zinc in the compound, resulting in the formation of copper(II) ions (Cu^
