Question

Is the following equation balanced? 2Na + 2H2O = 2NaOH + H2 Yes No

Answer 1

Yes there is an equal amount of atoms on either side

Answer 2

Answer:

Yes

Explanation:

2Na + 2H2O → 2NaOH + H2

A chemical equation is balanced if the number of atom of elements on the reactant side is equal to the number of atom of elements on the product sides.

According to the equation above the chemical equation is balanced .From the equation 2 moles of sodium reacted with 2 moles of water to form 2 moles of sodium hydroxide and hydrogen gas.

On the reactant side(left side), the sodium has 2 atom of sodium and the water molecule has 4 atom of hydrogen and 2 atom of oxygen.

On the product side(product side), the sodium hydroxide compound have 2 atom of sodium , 2 atoms of oxygen and 2 atoms of hydrogen . The hydrogen gas has 2 atoms of hydrogen. Adding the hydrogen atom on the product side will give you 4 atoms of hydrogen.

From the illustration above you could notice the equation is balanced.
