Balance the following equations : 1. Fe + H2 SO4 ---> Fe2(SO4)3 + H2
2. C2H6 + O2 ---> H2O + CO2
3. KOH + H3PO4 ---> K3PO4 + H2O
4. SnO2 + H2 ---> Sn + H2O
5. NH3 + O2 ---> NO + H2O
6. KNO3 + H2CO3 ---> K2CO3 + HNO3
7. B2Br6 + HNO3 ---> B(NO3)3 + HBr
8. BF3 + Li2SO3 ---> B2(SO3)3 + LiF
9. (NH4)3PO4 + Pb(NO3)4 ---> Pb3(PO4)4 + NH4NO3
10. SeCl6 + O2 ---> SeO2 + Cl2

what is this dude i cant and thank you sa points

1. 2 Fe + 3 H2SO4 = Fe2(SO4)3 + 3 H2

2. 2 C2H6 + 7 O2 = 6 H2O + 4 CO2

3. 3 KOH + H3PO4 = K3PO4 + 3 H2O

4. SnO2 + 2 H2 = Sn + 2 H2O

5. 4 NH3 + 5 O2 = 4 NO + 6 H2O

6. 2 KNO3 + H2CO3 = K2CO3 + 2 HNO3

7. B2Br6 + 6 HNO3 = 2 B(NO3)3 + 6 HBr

8. 2 BF3 + 3 Li2SO3 = B2(SO3)3 + 6 LiF

9. 4 (NH4)3PO4 + 3 Pb(NO3)4 = Pb3(PO4)4 + 12 NH4NO3

10. SeCl6 + O2 = SeO2 + 3 Cl2

Step-by-step explanation:

uhhh i dont know if its right

x+y=90

x=30-y=x

step-by-step explanation:

if you understand you will get the answer

the answer is 62.8 cubic units
