The answer is a throw the ball with greater force
The conversion for cm³ to ml is:
1 cubic centimetre = 1 millimetre
Therefore,
2 cubic centimetres = 2.0 millimetres
And so, your answer is E (but the cm should be cm³).

The reaction is balanced
The equilibrium constant is defined as the concentration ratio of the products and reactants. They are not considered pure solids and liquids.

So the answer is option B.
Balanced chemical equation: 2H2 + O2 → 2H2O
The limiting reagent will be H2
All 10.39 mol of H2 will be used up produce 10.39 mol of H20
The excess reagent will be O2 and there will be 5.78 mols left over
<span> Advantage: CO2 isn't as toxic as CO. Disadvantages: Can get a mixture of oxygen isotopes in CO2, so some species would effuse at about the same rate." But I'm jumping into AP Chem with no prior knowledge so I don't understand anything.</span>
