Answer:

Ca3(PO4)2 + 3H2SO4 —> 3CaSO4 + 2H3PO4

The coefficients are 1, 3, 3, 2

Explanation:

Ca3(PO4)2 + H2SO4 —> CaSO4 + H3PO4

From the above equation,

There are 3 atoms of Ca on the left and 1 atom of Ca on the right. To balance Ca, put 3 in front of CaSO4 as shown below

Ca3(PO4)2 + H2SO4 —> 3CaSO4 + H3PO4

Now, we have 3 atoms of SO4 on the right and 1atom on the left. To balance SO4, put 3 in front of H2SO4 as shown below:

Ca3(PO4)2 + 3H2SO4 —> 3CaSO4 + H3PO4

Looking closely, there are 6 atoms of H on the left and 3 on the right. Therefore, it is balanced by by putting 2 in front of H3PO4 as shown below:

Ca3(PO4)2 + 3H2SO4 —> 3CaSO4 + 2H3PO4

The coefficients are 1, 3, 3, 2

Water can be formed in the following reaction:

andreev551 [17]

Answer is: 10 moles of water will be produced.

Balanced chemical reaction of formation of water:

2H₂ + O₂ → 2H₂O.

n(H₂) = 10 mol; amount of hydrogen gas.

From balanced chemical reaction: n(H₂) : n(H₂O) = 2 : 2 (1 : 1).

n(H₂O) = n(H₂).

n(H₂O) = 10 mol; amount of water.

What isotope is used for a standard for other atomic masses?

sergeinik [125]

Though the ratio of any two atom's masses was the same on either scale, it was horribly confusing, so in 1961, a compromise was reached. Instead of using either Hydrogen, or Oxygen as the standard, the isotope of Carbon with 6 protons and 6 neutrons in its nucleus (Carbon-12) was given a mass of exactly 12.
