Answer:

The number of atoms is the same in the reactants and in the products, and the total mass is the same in the reactants and in

the products

Explanation:

For an equation to termed balance, the number of atoms of elements in the reactants must be equal to the number of atoms of the same element in the product.

The law of conservation of mass states that matter can neither be created nor destroyed during a chemical reaction but changes from one form to another. An unbalanced equation simply means that matter have been created or destroyed. This implies that balancing equation supports the laws of conservation of mass

Answer:

K I will attempt

Explanation:

$O_2_{(g)}+ 2H_2_{(g)} => 2H_2O_{(l)}\\$

1 : 2 : 2 (I don't know if this is what the question wants but it is what I would answer)

Hydrogen because it requires 2 moles of H2 to react with 1 mole of O2

24 moles of water. Look at stoichiometric coefficient. 2:2 means 24 moles you get 24 moles

Oxygen. 2 < 5/2. Remember, 1 mole of O2 requires 2 moles of H2. But 5/2 is still greater than 2

First, let's find out how many moles of water we can get. Since O2 is the limiting reactant, and O2:H2O ratio is 1:2, we will get 4 moles of H2O. Then, we can multiply 4 by Avogadro's number which is $6.022*10^{23}$ to get the number of molecules. We get: 2.41 * 10^24 molecules of water.
