Answer: scientific explanation
Explanation:
A really good scientific explanation should do two main things: It should explain all the observations and data we have. It should allow us to make testable predictions that we can check using future experiments.
Hydrochloric acid ionisation is as follows;
HCl ---> H⁺ + Cl⁻
HCl is a strong base so there's complete dissociation of acid to H⁺ ions
The number of HCl moles is equivalent to number of H⁺ ions present
1 L of solution contains - 11.6 moles of H⁺ ions
In 35 ml number of moles - 11.6 mol/L / 1000 ml x 35 ml = 0.406 mol
This number of moles are dissolved in 500 ml
therefore molarity = 0.406 mol /500 ml x 1000 ml = 0.812 M
According to Boyle's law, if the temperature were tripled as the number of moles and the volume were held constant, the pressure would triple (option C).
<h3>What is Boyle's law?</h3>
Boyle's law is the observation that the pressure of an ideal gas is inversely proportional to its volume at constant temperature.
However, when the temperature of a gas is increased, the pressure of the gas also increases provided the volume is constant.
According to this question, the temperature of a gas tripled as the number of moles and the volume were held constant.
Therefore, according to Boyle's law, if the temperature were tripled as the number of moles and the volume were held constant, the pressure would triple.

Answer:
The compound is ionic
The compound has a high melting point
The compound will conduct electricity in aqueous solution
The compound will be soluble in water
Explanation:
Now, let us consider the nature of the compound formed when a metal X looses two electrons and a non metal Y accepts one electron.
The compound formed must be ionic in nature with a formula XY2. Ionic compounds are formed by transfer of electrons from metals to nonmetals.
The ionic substance formed is always soluble in water with a high melting point. Usually, ionic solids do not conduct electricity in the solid state because the charge carriers (ions) are tightly bound in the crystal structure while in the solid state. In aqueous solution, the ions are relatively free hence ionic substances conduct electricity in aqueous solution.
