Chemistry

The theoretical yield : 31.11 g

Further explanation

Given

Reaction

3H2+N2=2NH3

Required

the theoretical yield

Solution

mol of Hydrogen :

mol = mass : Ar

mol = 5.5 g : 2

mol = 2.75

mol of Ammonia :

From the equation, mol ratio of H₂ : NH₃ = 3 : 2, so mol NH₃ =

$\tt \dfrac{2}{3}\times 2.75=1.83$

Mass Ammonia (MW=17 g/mol):

mass =mol x MW

mass = 1.83 x 17

mass= 31.11 g

From top to bottom electropositivity increases

Left to right it reduces

Explanation:

Electropositivity is also known as metallicity. It is a measure of the tendency of atoms of an element to lose electrons. It is closely related to the ionization energy and indeed the electronegativity.

The lower the ionization energy, the more electropositive a substance is. Across the period from left to right, electropositivity or metallicity decreases and from top to down a group, it increases.
