As the warm water holds more salt then cold water the fingers cool and produce crystals of salt that soon rains down to the floor of the ocean
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.

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.
Answer:
300 servings
Explanation:
there are 1000mgs in every gram so divide that by 100 to get the servings which is 10 then multiply it by 30 , once for each gram. and you get 300.
Answer : The number of moles of oxygen formed are, 0.255 moles.
Explanation :
The given chemical reaction is:

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
and
then we get the balanced chemical equation.
The balanced chemical reaction will be:

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