Amiraneli [1.4K]4 years ago
4 0

Answer:

the mass of potassium nitrate would be needed to produce a saturated solution of potassium nitrate in 50 grams of water at 313 K is

31g

Explanation:

To determine the mass of potassium nitrate needed to

produce a saturated solution of potassium nitrate in 50 grams of water at 313 K?, then it implies that we need to determine the

solubility of KNO3 is 62g KNO3 in 100g H2O at 313K. And this simply the amount of solute that when it dissolved in that water, then the water will not be able to take more solute again which means it has been saturated.that is the maximum quantity that the water can take at 313K.

If the solubility of KNO3 is 62g KNO3 in 100g H2O at temperature 313K

Then 50 g of water contains potassium nitrate = (62/100 X 50) at 313k = 31g

Therefore, the mass of potassium nitrate would be needed to produce a saturated solution of potassium nitrate in 50 grams of water at 313 K is

31g

4. Identify each substance in the following word equation as a reactant or a product
dolphi86 [110]

Explanation:

4.                 limestone heat lime + carbon dioxide

The reactants in this expression above is limestone

The products of the reaction is carbon dioxide and lime

Reactant is the species that gives the product and it is usually found on the left hand side of the expression.

The product is the substance on the right hand side of the expression that forms through the experiment.

Heat is used to facilitate the reaction.

5. An exothermic reaction is a reaction in which heat is given off.

An endothermic reaction is a reaction in which heat is absorbed in the process.

An exothermic reaction is always warmer after the reaction whereas an endothermic reaction is colder at the end of the reaction.

6.  Sodium salicylate is made from carbon dioxide and sodium phenoxide.

The reactants are:

                  Carbon dioxide and sodium phenoxide

The product is:

         Sodium salicylate

What is the final volume of NaOH solution prepared from 100.0 mL of 0.500 M NaOH if you wanted the final concentration to be 0.1
suter [353]

Answer:

The final volume of NaOH solution is 30ml

Explanation:

We all know that

              V1S1 = V2S2

             or V1= V2S2÷S1

             or  V1= V2×S2×1/S1

             or   V1=100×0.15×1/0.50

                    V1= 30

∴30 ml NaOH solution is required to prepare 0.15 M from 100ml 0.50 M NaOH solution.
