Tetraphosphorous decoxice (p4o10) reacts with water to produce phosphoric acid.
1. write the balanced equation for this reaction. do not include states of matter in the equation.
2) determine the number of moles of p4o10 required to produce 5.00 moles of phosphoric acid.
3) determine the number of moles of water required to produce 5.00 moles of phosphoric acid

1) P4O10 + 6H20 → 4H3PO4

2)  1.25 moles of P4O10

3)  7.5 moles of water

Explanation:

1. Write the balanced equation for this reaction

P4O10 + 6H20 → 4H3PO4

2) Determine the number of moles of P4O10 required to produce 5.00 moles of phosphoric acid.

For 1 mole P4O10 consumed, we need 6 moles of water to produce 4 moles of H3PO4

If we get 5.00 moles of H3PO4, we'll have 5/4 = 1.25 moles of P4O10 consumed.

3) Determine the number of moles of water required to produce 5.00 moles of phosphoric acid

For 1 mole P4O10 consumed, we need 6 moles of water to produce 4 moles of H3PO4

If we have 5.00 moles of H3PO4, we'll get (6/4)*5 = 7.5 moles of water consumed.

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.  

it is stable as it is in group 0 which have full outer shells of electrons
