This is simple I am just confused
SOVA2 [1]

Answer:

They all have the same number of protons but different numbers of neutrons.

Explanation:

Elements will always have the same number of protons no matter the isotopes. Isotopes only change the number of neutrons. Silicon will always have 14 protons. So silicon-28 has 14 protons and 14 neutrons. Silicon-29 has 14 protons and 15 neutrons. Silicon-30 has 14 protons and 16 neutrons.

The solubility of KClO3(s) in water increases as the
algol [13]
<span>Answer: option (1) solubility of the solution increases.
</span><span />

<span>Justification:
</span><span />

<span>The solubility of substances in a given solvent is temperature dependent.
</span><span />

<span>The most common behavior of the solubility of salts in water is that the solubiilty increases as the temperature increase.
</span><span />

<span>To predict with certainty the solubility at different temperatures you need the product solubility constants (Kps), which is a constant of equlibrium of the dissolution of a ionic compound slightly soluble in water, or a chart (usually experimental chart) showing the solubilities at different temperatures.
</span><span />

<span>KClO₃ is a highly soluble in water, so you do not work with Kps.
</span><span />

<span>You need the solubility chart or just assume that it has the normal behavior of the most common salts. You might know from ordinary experience that you can dissolve more sodium chloride (table salt) in water when the water is hot. That is the same with KClO₃.


</span><span>The solubility chart of KlO₃ is almost a straight line (slightly curved upward), with positive slope (ascending from left to right) meaning that the higher the temperature the more the amount of salt that can be dissolved.</span>
