Why does CaCo3 powder reacts faster than marble chips?

It is faster when powder is used, because the surface area of the powder is greater. Because there is more surface area, there is more surface (exposed calcium carbonate particles) with which the HCl particles can collide.

Why do marble chips affect the rate of reaction?

Increasing the temperature of the acid increases the kinetic energy of each particle. When the acid particles move around faster, there is a greater chance of successful collisions between the acid and marble chips. Therefore rate of reaction increases because there are more collisions.

Which has the fastest rate of reaction powder or marble chips?

The reaction with powdered marble is faster. The smaller the pieces of marble are (in this case the powdered form is smallest), the greater the surface area for the reaction to take place. Only the molecules at the surface of the solid can react with the hydrochloric acid.

How does the size of the marble chips affect the rate of reaction?

The importance of collisions between particles in reactions But if you had the same mass of smaller chips, you have opened up a much larger surface area for the acid to attack. So you might expect that the smaller the marble chips were, the faster the reaction would be.

Why does rate of reaction decrease over time?

Typically, reaction rates decrease with time because reactant concentrations decrease as reactants are converted to products. Reaction rates generally increase when reactant concentrations are increased.

How does changing the size of the marble chips affect the rate of the reaction?

For a given quantity, if the chips are larger then the surface area is lesson. So reaction with the larger chips happens more slowly. Both sets of results are plotted on the same graph.

Why do marble chips fizz when added to acid?

Marble chips react with dilute hydrochloric acid to produce carbon dioxide gas. The rate of this reaction can be changed by changing the size of the marble chips.

Why do the eight small marble chips react faster than the large marble chip answer?

The eight small marble chips have a smaller surface area, so less frequent collisions. The eight small marble chips have a smaller surface area, so more frequent collisions.

Why does marble chips react with hydrochloric acid?

The calcium carbonate reacted with hydrochloric acid when the acid was poured into marble chips. Due to calcium carbonate’s higher reactivity, it displaced hydrogen in the hydrochloric acid. As a result, products of calcium chloride, carbon dioxide and water were formed.

What happens when you add hydrochloric acid to marble?

The higher the concentration of hydrochloric acid in the beaker, the faster the reaction will take place. This is because there will be more hydrochloric acid particles to collide with the marble chip particles. Therefore resulting in a quicker reaction.

What is the chemical equation for calcium carbonate and hydrochloric acid?

Below is the word equation for this reaction: Calcium Carbonate + Hydrochloric Acid = Calcium Chloride + Carbon Dioxide + Water Below is the fully balanced chemical equation for this reaction. More about Investigating the Rate of Reaction Between Marble Chips (Calcium Carbonate) and Hydrochloric Acid Aim.

What is the independent variable in the electroplating of marble chips?

The independent variable in my investigation will be the surface area of the Marble Chips, however their mass will need to be controlled as well as the amount of hydrochloric acid and its concentration (2moles) used in all experiments in order to make it a fair test.

Why is marbles so sensitive to degradation?

Marble is especially sensitive to the degrading by acidic chemicals, also to weathering. Acid rain is one of the top degradation agents for marble artefacts around the world.
