if 10 moles of A and 7.5 moles of B are taken in a flask, identify the value of moles of A4B3 produced in a reaction.​
natta225 [31]

The number of moles of A4B3 produced in a reaction is obtained  by stoichiometry.

The term stoichiometry refers to mass-mole relationship. The first step in solving this problem is by writing the correct reaction equation as follows;

4A + 3B -------> A4B3

If 4 moles of A yields 1 mole of A4B3

10 moles of A yields 10 * 1/4 = 2.5 moles of A4B3

Therefore, 2.5 moles of A4B3  is produced.

Identify which statement about a solution is correct. Group of answer choices The solution has the same physical state as the ph
zavuch27 [327]

Water can only be the solvent, never the solute is the statement about a solution that is correct.

  • The solute is the substance that, in general, is found in less quantity and that dissolves in the mixture.

  • The solvent, on the other hand, is the substance that usually appears in greater quantity and where the solute dissolves.

  • The most usual thing is that the solvent is the substance that establishes the physical state of the solution.

  • Water is considered a universal solvent, since it is the liquid that dissolves the most substances, a quality linked to its status as a “polar molecule”, this is due to its ability to form hydrogen bonds with other substances.

Solubility depends on the properties of a solvent that allow it to interact with a solute in a stronger way than the solvent particles do with each other.

In particular, the polar character of water makes it an excellent solvent for polar and ionic solutes, which are called hydrophilic.

Therefore, we can conclude that water can only be the solvent, never the solute is the statement about a solution that is correct.
