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.

The overall change in enthalpy of a reaction depends only on the reactants and the products. the path that is taken from the rea
vfiekz [6]

Answer:

Here is the complete statement: The overall change in enthalpy of a reaction depend ONLY ON REACTANTS AND THE PRODUCTS.

Explanation:

Change in enthalpy of a chemical reaction refers to the heat change that is associated with a chemical change when the pressure is held constant. Generally, chemical reaction involves the breaking of chemical bonds in the reactants and the formation of new chemical bonds in the products. The breaking and forming of bonds involve heat change; the amount of heat that is given off and absorb in each chemical reaction depend on the type of reactants and products that are involved in the chemical reaction.

_____ H2O2 → _____ H2O + _____ O2
never [62]

Answer : The number of moles of oxygen formed are, 0.255 moles.

Explanation :

The given chemical reaction is:

H_2O_2\rightarrow H_2O+O_2

This reaction is an unbalanced chemical reaction because in this reaction number of oxygen atoms are not balanced.

In order to balance the chemical equation, the coefficient '2' put before the H_2O_2 and H_2O then we get the balanced chemical equation.

The balanced chemical reaction will be:

2H_2O_2\rightarrow 2H_2O+O_2

Now we have to calculate the number of moles of oxygen formed.

From the balanced chemical reaction we conclude that,

As, 2 moles of hydrogen peroxide react to give 1 mole of oxygen

So, 0.51 moles of hydrogen peroxide react to give \frac{0.51}{2}=0.255 mole of oxygen

Therefore, the number of moles of oxygen formed are, 0.255 moles.
