Answer:

Phosphoric acid

Explanation:

Phosphoric acid is an oxyacid, which is formed when hydrogen combines with the polyatomic ion phosphate. The polyatomic ion for phosphate is $PO_4^-3$ . To combine this with hydrogen, we "criss-cross" the charges of phosphate (which has a charge of -3) and hydrogen (which has a charge of +1) to get $H_3(PO_4)_1$ , the same as $H_3PO_4$ .

To answer this question, we essentially reverse these steps. First, we would recognize that this is a hydrogen atom bonded with phosphate. Because phosphate is a polyatomic ion, we know that this is an oxyacid. Because it involves phosphate, we call it phosphoric acid.

I hope this helps!

Ainat [17]

Since the water is at 100 degrees then it take 40.6 kj/mol to change 1 mole of water at 100 degrees into steam at 100 degrees
the moles of water 8.22mol
since one mole take 40.6kj/mol 8.22mol will be =
8.22mol x 40.6 kj/mol =333.732 kj

In nature, oxygen has three common isotopes. The atomic masses and relative abundances of these isotopes are given in the table

Vaselesa [24]

Answer: The average atomic mass of oxygen is 15.999 amu

Explanation:

Mass of isotope O-16 = 15.995 amu

% abundance of isotope O-16= 99.759 % = $\frac{99.759}{100}=0.99759$
