answer

changing the temperature and increase in the pressure

Change in concentration, pressure, catalyst, inert gas addition, etc. have  no effect on concentration, pressure, catalyst, inert gas addition lead to a shift in equilibrium position .

Answer:

changing the temperature

Explanation:

In general, a reaction is said to be at equilibrium when the rate of consumption of the reactants equals the rate of formation of products. The dynamics of this state can be represented in terms of the 'equilibrium constant', Keq which is the ratio of the concentration of products to that of the reactants.

Consider a hypothetical reaction:

A ↔ B

Keq = \frac{[B]}{[A]}

Based on the above equation, the value of Keq should increase if the concentration of B i.e. the product is decreased. However, if concentration of B is decreased then based on Le Chatelier's principle, the equilibrium will shift in a direction to produce more of B such that a new equilibrium is established  and Keq remains undisturbed. This is also the case for changes in pressure.

It is only by changing the temperature does the value of Keq change.

The solubility of KClO3(s) in water increases as the

<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>

Identify the units used to measure volume mass.
Strike441 [17]

Answer:

The metric system uses units such as meter, liter, and gram to measure length, liquid volume, and mass, just as the U.S. customary system uses feet, quarts, and ounces to measure these.

Volume: 1 liter is a little more than 1 quart

Mass: 1 kilogram is a little more than 2 pounds

Length: 1 centimeter is a little less than half an

Which scientist performed the cathode ray experiment leading to the discovery of electrons
SVETLANKA909090 [29]

The scientist that performed the cathode ray experiment leading to the discovery of electrons is J.J. Thomson.

<h3>What is a cathode ray?</h3>

A cathode ray is a tube that contains negatively charged electrode( that is the cathode) which emits electrons when heated at a low pressure.

The cathode ray was used by the scientist, J.J. Thomson to find the ratio of charge to mass (e/m) of the electrons.

Therefore, the scientist that performed the cathode ray experiment leading to the discovery of electrons is J.J. Thomson.
