Answer:

HfCl3

Explanation:

Step 1

Divide the percent by mass of each element by its relative atomic mass

Hf- 62.2/178.5, Cl-37.4/35.5

0.348, 1.054

Step2

Divide through by the lowest ratio

0.348/0.348, 1.054/0.348

1, 3

Therefore the empirical formula is HfCl3

A is the answer

In an ozone molecule, the three atoms must be connected, so there must at least be a single bond between them. Place

dots in pairs around the oxygen atoms until each oxygen atom has eight valence electrons, starting with the atoms on the

outside and doing the central atom last if there are enough. Do not exceed the total number of valence electrons

identified in part A. Remember that the dashes between the oxygen atoms, which represent single bonds, each indicate

the presence of two valence electrons

What is the chemical reaction for Mg + NaOH also with the ionic equations and subscripts?
Roman55 [17]
The chemical reaction of magnesium and sodium hydroxide would yield magnesium hydroxide and sodium. The chemical reaction is expressed as:
Mg(s)+ 2NaOH(aq)→Mg(OH)2(s)+2Na
In ionic form,
Mg(s) + 2Na+ + 2OH−(aq)→Mg(OH)2(s) + 2Na
