2 AIPO4 + 3 BaCl2 --> 2 AICIz + 1 Baz(PO4)2
givi [52]

Answer:

12.3 moles of AlCl_{3} are produced by reacting 18.4 moles of BaCl_{2} .

Explanation:

Balanced reaction: 2AlPO_{4}+3BaCl_{2}\rightarrow 2AlCl_{3}+Ba_{3}(PO_{4})_{2}

According to balanced equation:

3 molecules of BaCl_{2} produce 2 molecules of AlCl_{3}

So 3N_{A} molecules of BaCl_{2} produce 2N_{A}  molecules of AlCl_{3} (N_{A} is avogadro number).

We know 1 mol of molecule = N_{A} number of molecules.

So 3 moles of BaCl_{2} produce 2 moles of AlCl_{3}.

Hence 18.4 moles of BaCl_{2} produce (\frac{2}{3}\times 18.4) moles of AlCl_{3} or 12.3 moles of AlCl_{3} .

Identify each type of bond:
zloy xaker [14]

Answer:

The type of bond between the Oxygen atom and the hydrogen is Covalent

this is because the 2 electrons are being shared by both hydrogen and oxygen

The type of bond this molecule makes as a whole is called a Hydrogen Bond

A hydrogen bond is formed because of the partial +ve and -ve charge in a molecule

The cause of the partial +ve and -ve charge is the comparatively high electronegativity of oxygen which makes the electron get attracted towards the oxygen atom while the hydrogens try to maintain the maximum distance from the lone pairs due to repulsion

Hope it helped

Analysis of an ore of calcium shows that it contains 13.61 g calcium and 21.77 g oxygen in a 46.28-g sample. Calculate the perce
kondor19780726 [428]

Answer:

29.41% of Calcium and 47.04% of Oxygen

Explanation:

The percent composition of an atom in a molecule is defined as 100 times the ratio between the mass of the atom and the mass of the molecule.

The mass of the molecule of the problem (Ore) is 46.28g. That means the percent composition of Calcium is:

13.61g / 46.28g * 100 = 29.41% of Calcium

And percent composition of Oxygen is:

21.77g / 46.28g * 100 = 47.04% of Oxygen
