Write formulas for each of the following compounds: a. potassium hydroxide b. calcium nitrate c. sodium carbonate d. carbon tetrachloride e. magnesium b

KOH, Ca(No3)2, Na2Co3, CCl4 and Mg2Br respectively.

Explanation:

Chemical formulas are alternative name for molecular formulas.

A chemical substance is one formed by the chemical union of two or more (combination elements) ingredients in definite proportions by weight.

Below the task is to write the IUPAC formulas for the compounds below.

The knowledge of the valency of the elements and the chemical symbols of the elements are keys to answering.

Valency of an element is the combining power of the element.

potassium hydroxide

K =+1 , OH= -1

KOH

calcium nitrate

Ca= +2 NO3= -1

Ca(No3)2

sodium carbonate

Na= +1 CO3= -2

Na2Co3

carbon tetrachloride

C= +1 Cl=-1

CCl4

magnesium bromide

Mg= +2 Br=-1

Mg2Br
