u realize that one of the birds she described sounds like one you have seen in your home state of Indiana. You remember that all organisms have common and scientific names.

Phosphorus pentachloride reacts with water to form hydrochloric acid and phosphoric acid. How many total moles of acid are forme
klio [65]

Answer:

0,13 moles of acid are produced

Explanation:

The reaction of the problem is:

PCl₅ + 4H₂O → 5HCl + H₃PO₄

Based on the reaction, 1 mole of PCl₅ produces 6 moles of acid (5 moles of HCl + 1 mole of H₃PO₄).

The molecular mass of PCl₅ is:

1P = 30,97g/mol + 5Cl = 5×35,45g/mol = <em>208,24 g/mol</em>

That means 4,5g of PCl₅ are:

4,5g PCl₅×(1mol / 208,24g) = 0,0216 moles of PCl₅. As 1 mole of PCl₅ produces 6 moles of acid, 0,0216 moles of PCl₅ produce:

0,0216 moles PCl₅ × (6 moles acid / mole of PCl₅) =

<em>0,13 moles of acid are produced</em>

I hope it helps!

What effect does rapid exhalation of CO2 during exercise have on the concentration of H2CO3 in the blood?
BARSIC [14]

If there is a constant loss of CO_{2}~(carbon~dioxide) the concentration of H_{2} CO_{3}~(carbonic~acid) will be affected and decrease since CO_{2} is a main component of H_{2}CO_{3}.


Hope it helped,
