the teacher prepares 2.50 liters (l) of a salt solution for a class experiment. how many quarts (qt) are in 2.50 l? (1 l =1.06 q

mariarad [96]

The amount of quarts in 2.50 L is 2.65 qt

<h3>How many quarts are in 2.50 l?</h3>

Since the teacher prepares 2.50 liters of salt solution for a class experiment, we require how many quarts there are in 2.50 liters.

Since we know that 1 L = 1.06 qt, converting liters to quarts, we have

2.50 L = 2.50 × 1 L

= 2.50 × 1.06 qt

= 2.65 qt

So, the amount of quarts in 2.50 L is 2.65 qt

12. Consider the reaction: 2H2+O2 2H2O Decreasing the temperature would the rate of reaction increase a. b. decrease not change

Artemon [7]

Answer: Option (b) is the correct answer.

Explanation:

As the given reaction is as follows.

$2H_{2} + O_{2} \rightarrow 2H_{2}O$

So, when we decrease the temperature for this reaction then there will be decrease in kinetic energy of reactant molecules. As a result, less number of collisions will take place.

Hence, there will be decrease in rate of chemical reaction.

Thus, we can conclude that in the given reaction decreasing the temperature would also decrease the rate of reaction.
