Answer 1

Answer:

sodium carbonate = Na2CO3

magnesium hydroxide = Mg(OH)2

plz mark brainlist and follow me

Answer 2

Answer:

Sodium Carbonate:NA2

Sodium Carbonate:NA2CO3

Sodium Carbonate:NA2CO3Magnesium Hydroxide:MG1OH2

Explanation:

Sodium Carbonate: SODIUM 'S (Na) Valency is 1.

Carbonate 's (CO3)Valency is 2.

So , when they 2 mix they form Na2Co3 because Carbonate 's valency is multiplied with Sodium 's valency.

It is written Na2Co3 because when 3 Carbon atom mixes with 1 Oxygen atom its forms CO3 .

Magnesium Hydrxide: MAGNESIUM 'S (Mg) Valency is 2.

Hydroxide's (OH) valency is 1.

So,when they 2 mix they form Mg1OH2 . I don't think I would explain more as you have already understood .
