Answer:

Please find the terms with their correct description in the explanation section.

Explanation:

An electrolyte is a substance that dissociates or ionizes into cations (positive charged ions) and anions (negative charged ions) in an aqueous solution. An electrolyte can either be strong or weak depending on how well it ionizes and its level of conductivity. However, a non-electrolyte neither ionizes in a solution nor conducts electricity.

Based on this;

1. Weak electrolyte: Has a medium level of conductivity i.e. partially conducts electricity

2. Strong electrolyte: Contains a complete solute

3. Non-electrolyte: Has little or no conductivity i.e. cannot conduct electricity because it doesn't dissociate into ions.

4. Strong electrolyte: Has the highest conductivity i.e. conducts electricity very well.

5. Strong electrolyte: Contains a completely dissociated solute i.e. the solute of the electrolyte separates into anions and cations completely.

6. Weak electrolyte: Contains a partially dissociated solute i.e. the ions of the solute do not ionize completely in the solution.

A solution of H2SO4 (90.08 g/mol) has 785.6 g of H2SO4 and 359 g of H2O. What is the molal concentration (molality)?
tekilochka [14]

The molality of H₂SO₄ solution is 24.2 m.

<u>Explanation:</u>

We need to find the molality of sulfuric acid.

Mass of sulfuric acid = 785.6 g

Mass of water = 359 g

We have to find the moles of H₂SO₄ by using its mass and molar mass as,

Moles of H₂SO₄ = $\frac{785.6g}{90.08 g/mol}

                         = 8.7 moles

Mass of the solution in kg =$\frac{359}{1000} =  0.359 kg

Molality = $\frac{moles}{solvent (kg)}

           = $\frac{8.7 mol }{0.359 kg}\\

          = 24.2 m

So molality of the H₂SO₄ solution is 24.2 m.

A balloon contains 0.950 mol of nitrogen gas and has a volume of 25.5 L. How many grams of N2 should be released from the balloo
kirill [66]
Answer:
Mass released = 8.6 g
Explanation:
Given data:
Initial number of moles nitrogen= 0.950 mol
Initial volume = 25.5 L
Final mass of nitrogen released = ?
Final volume = 17.3 L
Solution:
Formula:
V₁/n₁ = V₂/n₂
25.5 L / 0.950 mol = 17.3 L/n₂
n₂ = 17.3 L× 0.950 mol/25.5 L
n₂ = 16.435 L.mol /25.5 L
n₂ = 0.644 mol
Initial mass of nitrogen:
Mass = number of moles × molar mass
Mass = 0.950 mol × 28 g/mol
Mass = 26.6 g
Final mass of nitrogen:
Mass = number of moles × molar mass
Mass = 0.644 mol × 28 g/mol
Mass = 18.0 g
Mass released = initial mass - final mass
Mass released = 26.6 g - 18.0 g
Mass released = 8.6 g

Give the chemical symbol for the element with the ground‑state electron configuration [ Ar ] 4 s 2 3 d 1 . symbol: Determine the
Rus_ich [418]

Answer:

Sc (Scandium) has the given electronic configuration.

Explanation:

The given electronic configuration is [Ar]4s^{2}3d^{1}.

The last electron enters the d-subshell and hence is a d-block element known as Scandium with chemical symbol Sc.

For 4s subshell

n=4,l=0 and m ranges from -l to +l so m=0.

For 3d subshell

n=3,l=2 and m ranges from -l to +l so m can take values -2,-1,0,+1,+2

Note:

l values for subshells:

s : 0

p : 1

d : 2

f : 3 and so on.
