First balance H and C:
9 H --> 4.5*(2H in H2O) thus multplying by 2to get round figures gives:
18 H = 9*(2H in H2O)
2*(5 C) --> 10 (C in CO2)
So now you've got this incompletely balanced equation (?? O2)
2 C5H9O + ?? O2 --> 10 CO2 + 9 H2O
This counts for 10*2 + 9 * 1 Oxygen atoms at right side which will balance with 2 (O in C5H9O) and 27 (O in O2, thus 13.5 O2) and after multplying all molecular's by 2 to get round figures 4 C5H9O + 27 O2 --> 20 CO2 + 18 H2O Control:
To balance the equation, you need 2 molecules of HCN on the reactant side. This will give you the balanced equation: NaCN + H2SO4 -> Na2SO4 + 2HCN.
To balance the equation SO2 + H2S = S + H2O, we need to ensure that there are equal numbers of each type of atom on both sides of the equation. Begin by placing coefficients in front of the compounds to balance the number of sulfur and hydrogen atoms, then balance the oxygen atoms last by adjusting the coefficient for H2O. The balanced equation is SO2 + 2 H2S = 3 S + 2 H2O.
Ca + Br2 = CaBr2 doesn't need to be balanced.
2NH4Cl + Na2CO3 --> 2NH3 + CO2 + H2O + 2NaCl
The equation FeSO4 = Fe2O3 + SO2 + SO3 is not balanced. To balance it, one possible balanced equation could be: 2FeSO4 = Fe2O3 + 2SO2 + 2SO3.
liho+h2s=
3h2 + n2 ==> 2nh3
It is already balanced
C2h2+3o2=2c02+2h2o+2c
The correct answer is co2+c= 2co
The balanced equation is Ca(OH)2 + H2SO4 → CaSO4 + 2H2O.
To balance the equation, you need 2 molecules of HCN on the reactant side. This will give you the balanced equation: NaCN + H2SO4 -> Na2SO4 + 2HCN.
A quadratic equation.
To balance the equation SO2 + H2S = S + H2O, we need to ensure that there are equal numbers of each type of atom on both sides of the equation. Begin by placing coefficients in front of the compounds to balance the number of sulfur and hydrogen atoms, then balance the oxygen atoms last by adjusting the coefficient for H2O. The balanced equation is SO2 + 2 H2S = 3 S + 2 H2O.
If you want to balance the equation, then: 2Zn + O2 --> 2(ZnO)
Ca + Br2 = CaBr2 doesn't need to be balanced.
2NH4Cl + Na2CO3 --> 2NH3 + CO2 + H2O + 2NaCl
