Please explain how to find each answer solution.
svp [43]

Explanation:

1) Based on the octet rule, iodine form an <u>I</u>⁻ ion.

Therefore,

Option E is correct ✔

2) The electronic configuration of the sulfide ion (S²⁻) is :

₁₆S = 1s² 2s² 2p⁶ 3s² 3p⁴ or [Ne] 3s² 3p⁴

₁₈S²⁻ = 1s² 2s² 2p⁶ 3s² 3p⁶ or [Ne] 3s² 3p⁶

Therefore,

Option E is correct ✔

3) valence shell electron of

Halogens = 7

Alkali metal = 1

Alkaline earth metal = 2

Therefore,

Option D is correct ✔

4) Group 2 element lose two electron in order to achieve Noble gas configuration.

And here Group 2 element is Sr

Therefore,

Option B is correct ✔

5) Group 13 element lose three electron in order to achieve Noble gas configuration.

And here Group 13 element is Al

Therefore,

Option B is correct ✔

6) For a given arrangements of ions, the lattice energy increases as ionic radius <u>decreases</u> and as ionic charge <u>increases</u>.

Therefore,

Option A is correct ✔

How many kilojoules are absorbed when 0.772 mol of N2(g) reacts? N2(g) + 2NO(g) → 2N2O(g) ΔH = 73.8 kJ
ANEK [815]

Answer:

56.97kJ

Explanation:

1 mole of N2 reacts with 73.8kJ

0.772 mole of N2 reacts with xkJ

cross multiply

x= 0.772×73.8

=56.97kJ

I need an answer and explanation pls
OverLord2011 [107]

Answer:

Cl2 + 2NaBr --> 2NaCl + Br2

Explanation:

This is a single displacement reaction where one side of the ionic compound switches with the other.

So, Cl2 + NaBr ---> NaCl + Br2

This isolates the Bromine and puts the Chlorine in it's place.

Then, balance out the equation like so and you should get

Cl2 + 2NaBr --> 2NaCl + Br2

In order to separate the components of a binary mixture, the relative volatility should be a) less than unity b) equal to unity
Tresset [83]

Answer: Option (c) is the correct answer.

Explanation:

A binary mixture is defined as the mixture which contains two components in the aqueous medium. The two components are solute and solvent.

And, volatility is defined as the ability of a liquid solution or substance to readily change into vapors.

For a binary solution the expression for relative volatility is as follows.

              \alpha = \frac{\frac{y_{i}}{x_{i}}}{\frac{y_{j}}{x_{j}}} = K_{i}/K_{j}

where,    \alpha = relative volatility of more volatile component i

               y_{i} = vapor-liquid equilibrium concentration of component i in the vapor phase

               x_{i} = vapor-liquid equilibrium concentration of component i in the liquid phase

                y_{j} = vapor-liquid equilibrium concentration of component j in the vapor phase

                 x_{j} = vapor-liquid equilibrium concentration of component j in the liquid phase

So, when \alpha > 1 then separation by distillation is easier in nature.

Thus, we can conclude that in order to separate the components of a binary mixture, the relative volatility should be greater than unity.
