Answer:
yes it is balanced.
Explanation:
when you are balancing an equation you look at the elements or compounds on the reactants and product side, which must have the same number of elements on both sides. like the question above;
2 potassium on the reactant and product side.
2 chlorine on the reactant and product side.
6 oxygen on the reactant and product side.
That is false. Weight is not constant every place in the universe. Take space for example. It all depends on gravity. So, the answer is false.
Answer:
volume of 
Explanation:
Firstly balance the given chemical equation,

From the given balance equation it is clearly that,
2 mole of Li gives 1 mole of H2 gas
⇔
⇔
⇔
hence
3 mole of Li will give 1.5 mole H2 gas
therefore volume of gas produced from 3 mole Li at 
volume of H2=33.6 litre
