Question

Balance the following equations:
H2 + O2 = H2O
HCl + Mg = MgCl2 + H2
Ca + O2 = CaO
Al + Br2 = AlBr3
H2SO4 + NaOH = Na2SO¬4 + H2O
Fe2O3 + C = Fe + CO2
HNO3 + Mg(OH)2 = Mg(NO3)2 + H2O
C3H8 + O2 = CO2 + H2O

Answer 1

Answer:

2h2+o2 =2h20

mg+2hcl=mgcl2+h2

2ca+o2=2cao

2al+3br2=2albr3

2naoh+h2so4=na2so4+2h2o

fe2o3+ 3co=2fe+3co2

2hno3+mg(oh)2=mg(no3)2 + 2 h2o

c3h8+ 5o2=3co2+4h2o
