A new grill has a mass of 30.0 kg. you put 1.5 kg of charcoal in the grill. you burn all the charcoal and the grill has a mass o
atroni [7]

The reaction for burning of charcoal or complete combustion is as follows:

C(s)+O_{2}(g)\rightarrow CO_{2}(g)

From the above balanced reaction, 1 mole of carbon releases 1 mole of CO_{2} gas.

Converting mass of charcoal into moles as follows:

n=\frac{m}{M}

Molar mass of pure carbon is 12 g/mol thus,

n=\frac{1.5\times 10^{3} g}{12 g/mol}=125mol

The same moles of CO_{2} is released. Converting these moles into mass as follows:

m=n×M

Molar mass of CO_{2} is 44 g/mol thus,

m=125mol\times 44 g/mol=5.5\times 10^{3}g

Converting mass into kg,

1g=10^{-3}kg

Thus, total mass of gas released is 5.5 kg.

Balance the following reaction:
miv72 [106K]

 The balanced reaction is   as below

3A₂B  + 2DC₃→ 6 AC  + D₂B₃


The number that must be  to the left of AC   is 6

 Explanation

  • According to the law  of mass  conservation , the number of atoms in reactant side   must be equal  to number  to the number of atoms  in  product  side.
  • Therefore the equation above is balance  since  it obey the law of mass conservation.
  • For example there is 6 atoms  of A in reactant side and  6 in product side.
