Pls predict and balance the following Chemical equations 30points (5 per question) Will mark Brainliest

1. Na2(SO4) (aq) + Ba(NO3)2(aq) -->

2. Na(NO3)(aq) + NH4Cl(aq) -->

4. ZnCl2 (aq) + K (SO4) (aq) -->

5. ZnCl2 (aq) + Na2S (aq) -->

6. Na(C2H3O2) (aq) + Ag(NO3) (aq) -->

1. Na2SO4 + Ba(NO3)2 → NaNO3 + BaSO4

2. NaNO3 + NH4Cl → NaCl + NH4NO3

4. Sorry, I don't know

5. Refer to the attachment..

6. NaC2H3O2(aq) + AgNO3(aq) = NaNO3(aq) + AgC2H3O2

"you start with 15.67 g mgco3-xh2o, when heated and all the water is removed, you are left with 7.58 g mgco3 only.

therefore, you had 15.67 - 7.58 = 8.09g h2o  

moles of each :

7.58g mgco3 = ? moles = 7.58g / 83.4g/mole = 0.09moles  

8 09g h2o = ? moles = 8.09g / 18g/mole = 0.44moles  

molar ratio between the two by dividing both numbers by the smallest number :

0.09 / 0.09 = 1  

0.44 / 0.09 = 4.8  

mgco3-5h2o"
