The following data was collected when a reaction was performed experimentally in the laboratory.
Reptile [31]

The maximum amount of AlCl_3 produced during the experiment can be find out by knowing the Limiting Reagent.

Here, The maximum amount of AlCl_3 produced during the experiment is  400 grams

<h3>What is Limiting reagent ?</h3>

The limiting reagent (or limiting reactant or limiting agent) in a chemical reaction is a reactant that is totally consumed when the chemical reaction is stopped.

Now, According to the question,

Given ;

Number of moles of Al(NO_3)_3 - 4 moles

Number of moles of NaCl - 9 moles

To Find - Maximum amount of AlCl_3 produced during the reaction.

Solution ;

complete reaction ;

Al(NO_3)_3  + 3NaCl -->   3NaNO_3 + AlCl_3

To find the maximum amount of AlCl_3 produced during the reaction,

we need to find the limiting reagent.

Mole ratio Al(NO_3)_3  = 4/1 = 4

Mole ratio NaCl = 9/3 = 3

Thus, NaCl is the limiting reagent in the reaction.

Now, 3 moles of NaCl produces 1 mole of   Al(NO_3)_3

9 moles of NaCl will produce = 1/3 x 9 = 3 moles.

Weight of   Al(NO_3)_3 = 3 x 133.34 = 400 grams

Thus, 400 grams of   Al(NO_3)_3  is the maximum amount of   Al(NO_3)_3 produced during the experiment.

What change would increase the amount of solid solute able to be dissolved in liquid water?
Agata [3.3K]

Answer:

D: Increasing temperature

Explanation:

From collision theory, we know that the more the increase in collisions, the faster the rate of the chemical reaction.

Now, the amount of solid solute in a solvent will change with a corresponding change in temperature. What we mean is that, the higher the temperature increases, the higher the number of collisions between the solvent molecules as well as leading to an increase in the solute particles which will mean an increase in the amount of the solid solute dissolved. The correct answer is option D.

7 on the pH scale represents what?
Nitella [24]

Answer:

seven on the ph scale is the neutral point

Explanation:

The range goes from 0 - 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water.
