What is the purpose of writing Shorthand Electron Configuration Using Noble Gases?

Chemistry
1 answer:
stepan [7]3 years ago
6 0

Noble gas electron configurations are easier to write because they are shorter then full electron configurations. They Noble gas shortcut electron configuration is a way of summarizing the information about the electrons of an atom.

If .00327 g of a gas dissolves in 0.376 L of water at 867 torr, what quantity of this gas (in grams) will dissolve at 759 torr?
Vinil7 [7]

At 759 torr, 0.002 86 g of the gas will dissolve.

Henry’s law states:

c = k_{H}p, where

where K_{H} is a proportionality constant called the Henry's Law constant.

If we have the same solute in the same solvent at two different pressures  p_{1} and p_{2},  

c_{1} = k_{H}p_{1} and c_{2} = k_{H}p_{2}

Dividing the two equations, k_H cancels and we get

c_1/c_2 = p_1/p_2

<em>c</em>_2 = <em>c</em>_1 × <em>p</em>_2/<em>p</em>_1

The volumes of solvent are the same, so we can use the masses of the solute instead of concentrations.

∴ <em>c</em>_2 = 0.003 27 g × (759 torr/867 torr) = 0.002 86 g

. Calculate the molality of each of the following solutions: (a) 0.710 kg of sodium carbonate (washing soda), Na2CO3, in 10.0 kg
Step2247 [10]

Answer:

a)0.67 molal

b) 5.67 molal

c) 2.82 molal

d) 0.0268 molal

Explanation:

Step 1: Data given

Molality = moles solute / mass solvent

(a) 0.710 kg of sodium carbonate (washing soda), Na2CO3, in 10.0 kg of water—a saturated solution at 0°C

Calculate moles of Na2CO3 =  710 grams / 105.99 g/mol = 6.70 moles

Molality = 6.70 moles / 10 kg = 0.67 molal

(b) 125 g of NH4NO3 in 275 g of water—a mixture used to make an instant ice pack

Calculate moles of NH4NO3 = 125 grams / 80.04 g/mol = 1.56 moles

molality = 1.56 moles / 0.275 kg = 5.67 molal

(c) 25 g of Cl2 in 125 g of dichloromethane, CH2Cl2

Calculate moles Cl2 = 25 grams / 70.9 g/mol= 0.353 moles

Molality = 0.353 moles / 0.125 kg = 2.82 molal

0.372 g of histamine, C5H9N, in 125 g of chloroform, CHCl3

Calculate moles histamine = 0.372 grams / 111.15 g/moles = 0.00335 moles

Calculate molality = 0.00335 moles / 0.125 kg = 0.0268 molal

NOTE: histamine is C5H9N3 not C5H9N
