Using the solubility curves, approximately how many grams of NaNO3 can be dissolved in 100. grams of water at 80 °C?
2 answers:
Answer:
As temperature increases, its solubility increases as well. Notice, however, that it does not increase significantly. In fact, you can expect to be able to dissolve no more than 40 g of sodium chloride per 100 g of water at 80∘C .
You can determine how many grams of sodium chloride, commonly known as table salt, can be dissolved in
100 g
of water at
80
∘
C
by taking a look at its solubility graph.
A substance's solubility graph tells you how its solubility changes, let's say starting from room temperature, when temperature is either decreased or increased.

Write the net ionic equation for the below chemical reaction:
(c):
<u>Answer:</u> The net ionic equation is
<u>Explanation:</u>
Net ionic equation is defined as the equations in which spectator ions are not included.
Spectator ions are the ones that are present equally on the reactant and product sides. They do not participate in the reaction.
(c):
The balanced molecular equation is:
The complete ionic equation follows:
As ammonium and chloride ions are present on both sides of the reaction. Thus, they are considered spectator ions.
The net ionic equation follows:
