The following reaction shows sodium hydroxide reacting with sulfuric acid.
elena-14-01-66 [18.8K]

The amount of  Na₂SO₄ would be 15.09 grams

<h3>Stoichiometric calculation</h3>

From the equation of the reaction:

4NaOH + 2H₂SO₄ --> 2Na₂SO₄ + 4H₂O

Mole ratio of NaOH and Na₂SO₄ = 2:1

Mole of 8.50 grams of NaOH = 8.50/40

                                                 = 0.21 mole

Equivalent mole of Na₂SO₄ = 0.21/2

                                              = 0.11 mole

Mass of 0.11 mole Na₂SO₄ = 0.11 x 142.04

                                             = 15.09 grams

Hello please please help me​
olga nikolaevna [1]

Answer:

            Option-A is the correct answer

Explanation:

Lithium belong to group 1 metals. Hence, it can loose one electron to form lithium ion i.e. Li⁺¹ or Li⁺

While, Nitrogen is non-metal and hence has the ability to gain the electron lost by lithium metal. Furthermore, Nitrogen can gain maximum 3 electrons to acheive noble gas configuration. Hence, three Li atoms will loose their electrons and Nitrogen will gain those three electrons to form nitride ion i.e. N³⁻.
