Question

(WILL MARK BRAINLIEST) PLZ HELP ASAP

Answer 1

Answer:

a) 2NaOH(aq) + CuSO4(aq) -------------> Cu(OH)2(s) + Na2SO4(aq)

b) Ca(OH)2(aq) + CO2(g) --------------> CaCO3 + H2O (this is already balanced)

c) Pb(NO3)2 + H2SO4 --------> PbSO4 + 2HNO3.

d) 2KNO3 ------> 2KNO2 + O2

e) H2SO4 + 2(NaOH) -----> Na2SO4 + 2(H2O)

f) Ca(NO3)2(aq) + (NH4)2CO3(aq) ----------------> CaCO3(s) + 2NH4NO3(aq)

Answer 2

Answer:

a) 2NaOH(aq) + CuSO4(aq) ----> Cu(OH)2(s) + Na2SO4(aq)

b) Ca(OH)2(aq) + CO2(g) --> CaCO3 + H2O (the chemical equation is already balanced as is)

c) Pb(NO3)2 + H2SO4 --> PbSO4 + 2HNO3

d) 2KNO3 --> 2KNO2 + O2

e) H2SO4 + 2(NaOH) --> Na2SO4 + 2(H2O)

f) Ca(NO3)2(aq) + (NH4)2CO3(aq) --> CaCO3(s) + 2NH4NO3(aq)
