A solid reactant is placed into a beaker of a warm water. The liquid vigorously bubbles as the solid dissolves into the solution
Nataly [62]

Answer:

Fewer bubbles will be produced because of fewer collisions of reactant molecules

Explanation:

As the solid dissolves into the solution after the liquid has been vigorously bubbled, if the temperature of the liquid is reduced a little, what will happen is that fewer bubbles will be produced as a result of lesser amount of collisions occurring between the reactant molecules

Consider the solubilities of a particular solute at two different temperatures. Temperature ( ∘ C ) Solubility ( g / 100 g H 2 O
grin007 [14]

Answer:

21.28 grams solute can be added if the temperature is increased to 30.0°C.

Explanation:

Solubility of solute at 20°C = 32.2 g/100 grams of water

Solute soluble in 1 gram of water = \frac{32.2}{100}g=0.322 g

Mass of solute in soluble in 56.0 grams of water:

0.322\times 56.0=18.032 g

Solubility of solute at 30°C = 70.2g/100 grams of water

Solute soluble in 1 gram of water = \frac{70.2}{100}g=0.702 g

Mass of solute in soluble in 56.0 grams of water:

0.702 \times 56.0=39.312 g

If the temperature of saturated solution of this solute using 56.0 g of water at 20.0 °C raised to 30.0°C

Mass of solute in soluble in 56.0 grams of water 20.0°C = 18.032 g

Mass of solute in soluble in 56.0 grams of water at 30.0°C = 39.312 g

Mass of of solute added If the temperature of the saturated solution increased to 30.0°C:

39.312 g - 18.032 g = 21.28 g

21.28 grams solute can be added if the temperature is increased to 30.0°C.
