Explanation:
water is a pure substance because it only contains one type of molecule.
The Earth, Mars or Jupiter should be denser than the Sun. Density is defined by mass and volume — components of object or matter. Although the sun is huge, it’s component is made up of mostly gas (hydrogen and helium). While Earth, though smaller than the Sun, contains heavier elements such as iron, sulfur, rocks, sediments, granite, basalt and water. Mars (composed of rocks and nutrients) and Jupiter (contains gases and compounds) as well are denser when compared to the Sun’s density. Referencing to our basic understanding of matter: solid and liquid should be heavier than gas.
<span>When silver nitrate reacts with sodium chloride, it produces silver chloride and sodium nitrate. The chemical reactions contains a one to one ratio of each compound on the reactant side and the products side.
In order to determine the correct answer, we must first convert the 25.0 milliliters to moles using:
moles = concentration * volume.
25 ml = 0.025 L
Moles of both reactants = 0.25 * 1 = 0.025
Now we have to calculate the mass of AgCl which is found by adding the atomic weight of silver and chlorine. The mass of AgCl is 143.3 g/mol. Multiplying 143.3 g/mol by 0.025 moles results in a mass of 3.58 grams of AgCl being produced.</span>
Among the choices the statement about crystal lattice energy is best supported by the information in the table is <span>The lattice energy increases as the charge of anions increases, as shown by LiF and LiCl. The answer is B.

<u>Answer:</u>
<em>To raise the pH of the solution to 3.10 we have to add 2.34 L of water.</em>
<u>Explanation:</u>
<em>Given that the pH of the solution of HCl in water is 2.5.</em> Here the solution’s pH is changing from 2.5 to 3.10 which means the acidic nature of the solution is decreasing here on dilution.
ions contribute to a solution’s acidic nature and
contribute to a solution’s basic nature.
The equation connecting the concentration of
and pH of a solution is pH= ![-log[H^+]](https://tex.z-dn.net/?f=-log%5BH%5E%2B%5D)
<em>![[H^+]= 10^(^-^p^H^)](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D%2010%5E%28%5E-%5Ep%5EH%5E%29)
