Answer 2

Calcium Carbonates and Salt React to Produce Carbon Dioxide Gas

Calcium carbonates and salt react to produce carbon dioxide gas. The chemical reaction can be represented as follows:

CaCO3 + 2NaCl → CaCl2 + CO2 + Na2CO3

In this reaction, calcium carbonate (CaCO3) and sodium chloride (NaCl) react to form calcium chloride (CaCl2), carbon dioxide (CO2), and sodium carbonate (Na2CO3) [[1]].

Reaction Time with Varying Amounts of Coal

To investigate the reaction time with varying amounts of coal, we can perform the following experiment:

1. Take different amounts of coal, such as 10g, 20g, 30g, 40g, 50g, 60g, 70g, 80g, 90g, and 100g. 2. Mix each amount of coal with a fixed amount of salt, such as 10g. 3. Observe and record the time it takes for the reaction to occur for each mixture.

The reaction time can be plotted on a graph with the amount of coal on the x-axis and the reaction time on the y-axis. This will help us visualize the relationship between the amount of coal and the reaction time [[2]].

Relationship between Reaction Rate and Concentration of Reactants

The reaction rate is influenced by the concentration of reactants. According to the collision theory, the reaction rate increases with an increase in the concentration of reactants. This is because a higher concentration leads to more frequent collisions between particles, increasing the chances of successful collisions and therefore increasing the reaction rate [[3]].

In the case of the reaction between calcium carbonates and salt, the concentration of coal can be considered as a measure of the concentration of the reactant. As the concentration of coal increases, the reaction rate is expected to increase, resulting in a shorter reaction time. This can be observed in the graph mentioned earlier, where a steeper slope indicates a higher reaction rate [[3]].

It is important to note that the reaction rate is not solely determined by the concentration of reactants. Other factors, such as temperature, catalysts, and surface area, can also affect the reaction rate [[4]].

Conclusion

In conclusion, the reaction between calcium carbonates and salt produces carbon dioxide gas. The reaction time can be investigated by varying the amount of coal and observing the time it takes for the reaction to occur. The relationship between the reaction rate and the concentration of reactants can be explained by the collision theory, where a higher concentration leads to a higher reaction rate. However, it is important to consider other factors that can influence the reaction rate.
