Ionization energy is a measure of the ability of atoms to attract electrons within a bond. True False
Xelga [282]

Answer:

The correct option is False

Explanation:

Ionization energy is the <em>minimum amount of energy required to remove a valence electron from one mole of an atom in it's gaseous state</em>. Ionization energy requires the removal of an electron from a gaseous atom. The definition in the question is that of electronegativity.

Electronegativity is the <u>ability of an atom to attract electrons towards itself in a chemical bond.</u>

Ammonia will decompose into nitrogen and hydrogen at high temperature. An industrial chemist studying this reaction fills a 500.
yaroslaw [1]

Answer:

12. is the pressure equilibrium constant for the decomposition of ammonia at the final temperature of the mixture.

Explanation:

2NH_3(g)\rightleftharpoons N_2(g)+3H_2(g)

initially

3.0 atm      0              0

At equilibrium

(3.0-2p)     p               3p

Equilibrium partial pressure of nitrogen gas = p = 0.90 atm

The expression of a pressure equilibrium constant will be given by :

K_p=\frac{p_{N_2}\times (p_{H_2})^3}{(p_{NH_3})^2}

K_p=\frac{p\times (3p)^3}{(3.0-2p)^2}

=\frac{0.90 atm\times (3\times 0.90 atm)^3}{(3.0-2\times 0.90 atm)^2}

K_p=12.30\approx 12.

12. is the pressure equilibrium constant for the decomposition of ammonia at the final temperature of the mixture.

What mass of water would be produced if 1.5 g of ethanoic acid was reacted completely with sodium hydroxide (3 marks)
Zigmanuir [339]

Mass of water : 0.45 g

<h3>Further explanation</h3>

Given

1.5 g ethanoic acid

Required

Mass of water

Solution

Reaction

<em>CH₃COOH + NaOH ⇒H₂O + CH₃COONa</em>

mol CH₃COOH(MW=60 g/mol) :

= mass : MW

= 1.5 : 60

= 0.025

mol H₂O from the equation :

= 0.025(mol ratio CH₃COOH : H₂O= 1 : 1)

Mass of water :

= mol x MW water

= 0.025 x 18 g/mol

= 0.45 g
