A 9.03 g sample of magnesium reacts completely with 3.48 g of nitrogen to form a compound of

hjlf

Answer:

12.5 g

Explanation:

12.5 g of the compound would be formed.

First, let us look at the balanced equation of reaction.

$3 Mg(s) + N_2(g) --> Mg_3N_2(s)$

3 moles of Mg is required to react with 1 mole of N2 to produce 1 mole of product.

Recall that: mole = mass/molar mass

9.03 g of Mg = 9.03/24.3 = 0.3716 mole

3.48 g of N2 = 3.48/28 = 0.1243 mole

Mole ratio of Mg/N2 = 3:1

Hence, there is no limiting reactant.

3 moles of Mg is required for 1 mole of product.

0.3716 mole of Mg will therefore require:

0.3716 x 1/3 = 0.1239 moles of product.

Molar mass of product $Mg_3N_2$ = 100.9 g/mol

Mass of 0.1239 mole $Mg_3N_2$ = mole x molar mass

= 0.1239 x 100.9 = 12.5 g

During the electrolysis of cryolite ,aluminium and fluorine are formed in.......molar ratio

PtichkaEL [24]

${\huge{\boxed{\sf{\pink{☛Answer࿐}}}}}$

From the first mechanism, it can be seen that the Aluminum is reduced at cathode and Florine is oxidized at anode.

The ratio of aluminium and fluorine is the ratio of their change in oxidation number, i.e. 2:3
