mechanism with a small activation energy or one with large activation energy​

Answers

Answer 1

Answer:

Rate depends on the rate constant. The rate constant depends on temperature and activation energy. If you have lower activation energy the rate will be higher. This is why catalysts are added since catalysts provide an alternate pathway that requires lower activation energy and catalysts are added to increase the rate of reaction.

Explanation:

This is only the answer if you were asking:

"Which corresponds to the faster rate: a mechanism with a small activation energy or one with a large activation energy?"

Thats what I understood about your question.

Describe a method for making pure crystals of magnesium chloride from magnesium and dilute hydrochloric acid. In your method, you should name the apparatus you will use. (6 mark question)

Answers

Answer:

Check Explanation.

Explanation:

Magnesium and dilute hydrochloric acid react with each other to produce Magnesium Chloride and liberate hydrogen gas according to the reaction

Mg (s) + 2HCl (aq) → MgCl₂ (aq) + H₂ (g)

The procedure to obtain pure magnesium chloride from the reaction is as thus

Step 1: Reaction

- Leave the dilute hydrochloric acid in a beaker.

- Add Magnesium slowly until it is in excess or until no more gas seem to be getting liberated.

Step 2: Filtration

- Filter with filter paper and funnel.

- Filter off the excess magnesium as magnesium chloride will be in aqueous form (liquid) and will come out with the filtrate. The residue is the excess magnesium.

Step 3: Crystallization to obtain solid crystals from the filtrate.

- Pour filtrate solution into evaporating dish/basin

- Provide heat using Bunsen burner

- Pour solution into an evaporating basin and heat over a water bath

- Stop heating when crystals start to form

allow water to evaporate until pure crystals remain.

- Dry crystals using absorbent paper or warm oven.

Precautions

- Use personal protective equipment such as gloves, a lab coat and wear eye protection, especially when heating.

- Avoid inhaling unnecessary gases during the whole process.

Hope this Helps!!!

Pure crystals of magnesium chloride using dilute hydrochloric acid can be prepared by using three steps, Reaction, Filtration, and Crystallization.

[tex]\bold {Mg (s) + 2HCl (aq) \rightarrow MgCl_2 (aq) + H_2 (g)}[/tex]

According to the reaction, when Magnesium react with dilute hydrochloric acid, produce Magnesium Chloride and hydrogen gas.

1: Reaction

Put dilute hydrochloric acid in a beaker and add Magnesium slowly  until no more gas seem to be produced. .

2: Filtration

Use filter paper and funnel.Since, magnesium chloride is in aqueous form and will come out with the filtrate(solution).

3: Crystallization:

Use water bath to evaporate water of filtrate.Turn of the water bath as crystals start forming.

Therefore, pure crystals of magnesium chloride using dilute hydrochloric acid can be prepared by using three steps, Reaction, Filtration, and Crystallization.
