Answer:

The correct answer would be heating the mixture.

The solubility of a solute in a particular solvent depends upon the temperature of the solution.

In most cases, the solubility of the mixture increases with increase in temperature of the mixture.

Higher temperature increases the kinetic energy of the solvent due to which it becomes more efficient in breaking apart the particles of the solutes.

It increases the solubility of the solute in a particular solvent.

Thus, more sugar can be added by heating the mixture.

In the laboratory you are asked to make a 0.565 m sodium bromide solution using 315 grams of water. How many grams of sodium bro
Scorpion4ik [409]

Answer : The mass of sodium bromide added should be, 18.3 grams.

Explanation :

Molality : It is defined as the number of moles of solute present in kilograms of solvent.

Formula used :

Molality=\frac{\text{Mass of solute}\times 1000}{\text{Molar mass of solute}\times \text{Mass of solvent}}

Solute is, NaBr and solvent is, water.

Given:

Molality of NaBr = 0.565 mol/kg

Molar mass of NaBr = 103 g/mole

Mass of water = 315 g

Now put all the given values in the above formula, we get:

0.565mol/kg=\frac{\text{Mass of NaBr}\times 1000}{103g/mole\times 315g}

\text{Mass of NaBr}=18.3g

Thus, the mass of sodium bromide added should be, 18.3 grams.

Define the following terms:
Marrrta [24]

Answer:

a)An endothermic reaction is any chemical reaction that absorbs heat from its environment. The absorbed energy provides the activation energy for the reaction to occur eg Melting of ice, Evaporating liquid water

   b)An Exothermic reaction is a chemical reaction that involves the release of energy in the form of heat or light.eg a spark, flame, or flash), electricity , a battery), or sound , explosion heard when burning hydrogen).

c)By definition an exothermic reaction produces heat as part of it’s process. The heat generated just by being alive is an exothermic process as well. And as such we become aware of when we feel “too cold” or “too hot” and try to either adjust to the conditions we are in, or minimize them, if possible. It is not merely odd, but contrary to intelligent living, that we choose to increase our discomfort and also risk our health by intentionally increasing not only the exothermic reactions we use but also maximize them to our own detriment. In short, the increased use of inefficient exothermic reactions while inexpensive in current evaluations of financial cost are extremely expensive in terms of it’s effect upon living things, including ourselves. It is as though we are choosing our homes to not only be next to a furnace, but as close as possible to the process.
