Kazeer [188]

Answer:

Bubbles will be formed when two solutions will be combined.

Explanation:

When the solution containing Na_{2}CO_{3} and HCl as a solute will be combined, the reaction will be as follows,

Na_{2}CO_{3}(aq) + 2HCl(aq) \rightarrow   2NaCl(aq)+ H_{2}O(l)+CO_{2}(g)

As a result of combination of the two solutions bubbles will be formed which will depict the evolution of carbon dioxide gas.

If the concentration of a KCl solution is 16.0% (m/v), then the mass of KCl in 26.0 mL of solution is ________.
melomori [17]

Answer:

The correct answer is 4.16 grams.

Explanation:

Based on the given information, the concentration of KCl solution is 16 % m/v, which means that 100 ml of the solution will contain 16 grams of KCl.

The molarity of the solution can be determined by using the formula,

M = weight/molecular mass × 1000/Volume

The molecular mass of KCl is 74.6 grams per mole.

M = 16/74.6 × 1000/100

M = 16/74.6

M = 2.14 M

Now the weight of KCl present in the solution of 26 ml will be,

2.14 = Wt./74.6 × 1000 /26

Wt. = 4.16 grams
