1. ____ + _________——————> HCl + Br2

2. _______ + ________ ———————> AgCl + NaNO3

3. HNO3 + Ca(OH)2 ——————> _______ + ________

4. Ca(NO3)2 + H2O ——————> ________ + ________

5. Na2CO3 + CaCl2 ——————> ________ + ________

Answer 1

Answer:

2) AgNO³+NaCl

3) HNO3+Ca(OH)2= Ca(NO3)2+H2O.

4) Ca(NO3)2 + H2O=HNO3 CA OH 2

5) Na2CO3 + CaCl2=CaCO3(s) + 2NaCl(aq)

Answer 2

Answer:

1. HBr + BrCl -----> HCl + Br2

2. AgNO3 + NaCl -----> AgCl + NaNO3

3. HNO3 + Ca(OH)2 -----> CaHNO3 + H2O2

4. Ca(NO3)2 + H2O -----> CaO + 2H(NO3)

5. Na2CO3 + CaCl2 ------> 2NaCl + CaCO3
