<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).

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
Answer:
An external stimuli is a stimulus that comes from outside an organism and causes a reaction.An internal stimuli is a stimulus that comes from inside an organism.
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.
