Predict the formulas for calcium chloride and potassium phosphate

Chemistry
1 answer:
Sauron [17]3 years ago
8 0

Answer:

CaCl2

And

potasium phosphate is a general name for salt of potassium and phosphate ions . The compounds can exist as

K3PO4 (Tripotassium phosphate)

K2HPO4 (di potassium phosphate)

KH2PO4 (mono potassium phosphate)

Explanation:

Calcium chloride salt is an ionic compound. so it contains both cations and anions. That means it has a positively charged ion and a negatively charged ion. In an ionic compound their is a transfer of electron. The valence electron or the charge ion present in an atom can be use to predict the chemical formula of this compound . Base on the compound the positive end is calcium while the negative end is chlorine .

Ca2+  and Cl-

cross multiply the charges

CaCl2

The charge of phosphate ions are (PO4)3−, (HPO4)2− and (H2PO4)−. And base on the valence electron potassium has a stable charge of +1 (K+). The phosphate ion produces the negative charge when it reacts with potassium.

If potassium goes into reaction with any of the phosphate ion it will be as follows.

K+  and  (PO4)3−

cross multiply the charge as usual

K3PO4(tripotassium phosphate)

K+ and (HPO4)2−

cross multiply the charge as usual

K2HPO4(di potassium phosphate)

K+ and (H2PO4)−

cross multiply the charge as usual

KH2PO4 (mono potassium phosphate)

How many moles of oxygen are needed for the complete combustion of 29.2 grams of acetylene?
podryga [215]

Moles of Oxygen= 2.8075 moles

<h3>Further explanation</h3>

Given

29.2 grams of acetylene

Required

moles of Oxygen

Solution

Reaction(Combustion of Acetylene) :

2 C₂H₂ (g) + 5 O₂ (g) ⇒ 4CO₂ (g) + 2H₂O (g)

Mol of Acetylene :

= mass : MW Acetylene

= 29.2 g : 26 g/mol

= 1.123

From equation, mol ratio of Acetylene(C₂H₂) : O₂ = 2 : 5, so mol O₂ :

= 5/2 x mol C₂H₂

= 5/2 x 1.123

= 2.8075 moles
