When a solute is added to a solution why does it remain homogeneous?
Olenka [21]
<h3>Answer:</h3>

                 When a solute is added to a solution, it remains homogeneous because the solute is soluble in given solvent.

<h3>Explanation:</h3>

                         Homogeneous mixtures, also called true solutions are those mixtures in which the components proportions are same throughout in any given sample. For example, the mixture of table salt (NaCl) and water. When the solution is unsaturated and further NaCl is added to it, it will dissolve the NaCl because the saturation point is still not reached. Remember, as "<em>Like Dissolves Like</em>" NaCl being polar in nature will interact with water molecules and will dissociate into Na⁺ and Cl⁻ ions surrounded by δ- O and δ+ H atoms of water molecules.

<h3>Conclusion:</h3>

                  In order to form a Homogeneous mixture the solution must be unsaturated, solvent must have affinity for incoming solute particles and the size of solute should be equal to 1 Â (Angstrom).

Given a balanced chemical equation between H2SO4(aq) and KOH(aq) H2SO4(aq) + 2 KOH(aq) → K2SO4(aq) + 2 H2O(l) What volume (in mL
Lynna [10]

Answer:

48.84mL

Explanation:

H2SO4 + 2KOH → K2SO4 + 2H2O

From the question:

nA = 1

nB = 2

From the question given we obtained the following information:

Ma = 0.43M

Va =?

Mb = 0.35M

Vb = 120mL

Using MaVa / MbVb = nA/nB, we can easily find the volume of the acid required. This is illustrated below:

MaVa / MbVb = nA/nB

0.43 x Va / 0.35 x 120 = 1/2

Cross multiply to express in linear form

2 x 0.43 x Va = 0.35 x 120

Divide both side by the (2 x 0.43)

Va = (0.35 x 120) /(2 x 0.43)

Va = 48.84mL

Therefore, the volume of H2SO4 required is 48.84mL

Which equation demonstrates that nuclear fusion forms elements that are heavier than helium
yan [13]

Answer: The correct option is, 2.

Explanation:

Nuclear fission: It is defined as the reactions in which a larger unstable nuclei breaks into two or more smaller stable nuclei.

Nuclear fusion: It is defined as the reaction where two smaller nuclei combine together to form a larger nuclei.

Option 1 & option 2 shows fusion reaction and option 3 & option 4 shows fission reaction.

In option 1, helium itself is forming but in option 2, element is heavier than forming which is, neon.

Hence, the correct option is 2.
