Question

choose the correct option

write chemical formulae of

a, sodium chloride

b, potassium nitrate

c, magnesium hydroxide

d, sodium oxide

​

Answer 1

Answer:

B

Potassium nitrate is correct option

Answer 2

Answer:

a.Sodium Chloride - NaCl

The formula for sodium chloride is NaCl. This represents a ratio of one sodium ion Na+ , to one chloride ion Cl− . This is an ionic compound made up of positive and negative ions.    

b.Potassium Nitrate - KNO3

Potassium nitrate is a chemical compound with the chemical formula KNO3. It is an ionic salt of potassium ions K+ and nitrate ions NO3−, and is therefore an alkali metal nitrate.

c. Magnesium Hydroxide - Mg(OH)2

Magnesium hydroxide is the inorganic compound with the chemical formula Mg(OH)2. It occurs in nature as the mineral brucite. It is a white solid with low solubility in water (Ksp = 5.61×10−12). Magnesium hydroxide is a common component of antacids, such as milk of magnesia, as well as laxatives.

d. Sodium Oxide - Na2O
