Balance the following equations

the balanced equations are :

1. 2 KI + Cl2 -> 2 KCl + I2

2. 2 C2H6 + 7 O2 -> 4 CO2 + 6 H20

3. 3 Mg(NO3)2 + 2 K3PO4 ->

Mg3(PO4)2 + 6 KNO3

i hope it helped

1) 2KI + Cl2 → 2KCl I2

2) 2C2H6 + 7O2 → 4CO2 + 6H2O

3) 3Mg(NO3)2 + 2K3PO4 → Mg3(PO4)2 + 6KNO3

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
