Amanda paired with Janice while Deja paired with Eden for a chemistry project. For the Earth science project, Amanda paired with
pashok25 [27]

The chemical reaction that the situation demonstrates would be a double replacement reaction.

In double replacement reactions, the two reactants participating in the reaction are similarly built in terms of their chemical bonds and they exchange ions to form the products of the reaction. Two products are also formed from the two reactants.

It is as opposed to single replacement reactions in which the two reactants are not similar bond-wise. One of the reactants replaces or displaces one of the ions in another reactant.

In this case, the situation can be represented as follows:

Amanda-Janice + Deja-Eden ----> Amanda-Eden + Deja-Janice

Thus, it is a form of double replacement reaction.

(V) A solution of hydrogen chloride is an electrolyte but a solution of
tiny-mole [99]

Answer:

When hydrogen reacts with chlorine, hydrogen chloride is formed. Hydrogen chloride is a gas, and has the formula HCl(g).

When hydrogen chloride dissolves in water, hydrochloric acid is formed. This has the same formula, but you can tell the difference because of the state symbol (aq), which stands for ‘aqueous’. The formula is written as HCl(aq).

Hydrogen chloride is made from molecules. The hydrogen atom and the chlorine atom are joined by a covalent bond. When hydrogen chloride forms hydrochloric acid, the molecules split into ions.

HCl(aq) → H+(aq) + Cl-(aq)

The H+ ions make this aqueous solution acidic. The solution also conducts electricity because it contains ions that are free to move.

However, when hydrogen chloride gas dissolves in a solvent called methylbenzene, the molecules do not split up. A solution of HCl in methylbenzene does not contain hydrogen ions, so it is not acidic. The solution also has a low electrical conductivity.

Diamonds are measured in carats, and 1 carat=0.200g. The density of diamond is 3.51g/cm^3. What is the volume of a 5.0-carat dia
const2013 [10]
Convert the amount of substance in carat to grams.
                 (5.0 carat) x (0.200 g / 1 carat) = 1 g
The volume of the substance is obtained by dividing the mass by the density,
                             v = m / d
                             v = 1 g / (3.51 g/cm³) = 0.2849 cm³
Therefore, the volume of a 5.0 carat diamond is approximately 0.285 cm³.
