<u>Answer:</u> The oxidation number of magnesium in magnesium chloride is +2.

<u>Explanation:</u>

Oxidation number is defined as the number that is assigned to an element when it gains or looses electrons. If an element gains electron, it will attain a negative oxidation number and if an element looses electron, it will attain a positive oxidation number.

The chemical formula for magnesium chloride is $MgCl_2$

We take the oxidation state of magnesium atom be 'x'.

Oxidation state of chlorine atom = -1

Evaluating the oxidation number of magnesium atom:

$x+2(-1)=0\\\\x=+2$

Hence, the oxidation number of magnesium in the given compound is +2.

Ca(OH)2 + H3PO4 = Ca3(PO4)2 + H2O

larisa [96]

Make a quick chart with each element represented, and count them up. HINT - leave the polyatomic anions together - in this case, PO4

Left Right
1 Ca 3
2 O 1
5 H 2
1 PO4 2

Begin by balancing like finding common denominators of fractions - apply to both sides:
I started by adding a 2 in front of H3PO4 on the left, them 6 in front of H2O on the right. Last, a 3 in front of Ca (OH)2. Then, re-count using the chart format to make sure you're right.

3Ca(OH)2 + 2H3PO4 = Ca3(PO4)2 + 6H2O
