What would be the total mass of the products of a reaction in which 10 grams of water decomposes into the elements hydrogen and oxygen?

Answer : The total mass of products of the reaction is 10 grams.

Explanation :

The balanced chemical reaction will be,

First we have to calculate the moles of water.

Now we have to calculate the moles of hydrogen and oxygen.

From the balanced reaction we conclude that

As, 2 mole of to give 2 mole of

So, 0.555 mole of to give 0.555 mole of

and,

As, 2 mole of to give 1 mole of

So, 0.555 mole of to give mole of

Now we have to calculate the mass of hydrogen and oxygen.

and,

Now we have to calculate the total mass of products.

Total mass of products = Mass of hydrogen + Mass of oxygen

Total mass of products = 1.11 g + 8.89 g

Total mass of products = 10 grams

Therefore, the total mass of products of the reaction is 10 grams.

the answer is 303.15 or 303

nuclear fission produces elements that are heavier than helium.

the elements that are used in nuclear fission and their products are much heavier than helium.
