Answer:

The intensity of the light bulb increases

Explanation:

The conductivity of a solution depends on the concentration of ions in solution. This implies that, if the concentration of ions in solution is increased, the conductivity of the solution increases accordingly.

If we add more CuSO4(s) to the CuSO4 solution, the concentration of ions in the solution and consequently the conductivity of the solution increases.

Therefore, the intensity of the light bulb increases.

Norma-Jean [14]
The distance covered will be:

d = v_0\cdot t + \frac{1}{2}a\cdot t^2 = 20\frac{m}{s}\cdot 5\ s + \frac{5}{2}\frac{m}{s^2}\cdot 5^2\ s^2 = \bf 162,5\ m

Based on patterns in the periodic table, which ion has a stable valence electron configuration?
kifflom [539]

The ions of Noble gases, <em>group VIII</em> elements have a full octet configuration on their outermost shell and as such are highly stable.

The periodic table is a systematic arrangement of elements in order of their atomic numbers into a set of 8 columns each called groups and a set of 7 rows each called a period.

Elements are arranged in different groups according to the number of Valence electrons they have.

  • For instance, elements in the group I of the periodic table are highly electropositive and as such are highly reactive.

The same is evident in group 7 elements are highly electronegative and have high electron affinity and as such are unstable and reactive.

  • However, Noble gases, <em>group VIII</em> elements have a full octet configuration on their outermost shell and as such are highly stable.

Consequently, the <em>Noble gases ion</em> has a stable Valence electron configuration.

Romashka-Z-Leto [24]

Answer:

.✓is related to the solute content

✓gives information about potential changes in cell volume when cells are placed in that solution

√is related to membrane permeability to solutes.

Explanation:

Tonicity of a solution can be explained as how an extracellular solution can give room for the liquid to move in and out of the cell through osmosis.

It should be noted that Tonicity of a solution is

.✓is related to the solute content

✓gives information about potential
