How did the rate of loss of the limestone change from the beginning of the experiment to the end?
The rate of loss of limestone increased as the experiment progressed. Initially, the reaction between the acid and limestone was slower, resulting in a lower rate of loss. However, as more limestone was consumed and the surface area for the reaction increased, the rate of loss of limestone accelerated.

How does sulfuric acid react with limestone?
if limestone is in a solid form it would degrade (hence a loss in mass of the limestone) and carbon dioxide would be given off. if it is in the powdered form the change in mass would not be very obvious and only a loss carbon dioxide would be seen.
If you heated limestone how would you expect the mass of the limestone to compare with the mass of calcium oxide?
When limestone is heated, it undergoes a chemical reaction that releases carbon dioxide gas, leaving behind calcium oxide. As a result, the mass of the limestone would be greater than the mass of the calcium oxide produced, due to the loss of carbon dioxide during the reaction.
What change is observe when a leave was boiled in warm water in a experiment?
When a leaf is boiled in warm water, the heat can cause the cell membranes in the leaf to rupture. This can result in the loss of color pigments in the leaf, causing it to turn pale or translucent. Additionally, the proteins in the leaf may denature due to the heat, leading to changes in the leaf's structure and texture.
How does high temperature affect limestone?
At high temperature, limestone undergoes thermal decomposition. The word equation is calcium carbonate decomposes when heated to calcium oxide and carbon dioxide. The chemical equation is CaCO3 + heat --> CaO + CO2.
If you melt magnesium metal is it a chemical change?
Yes, the combustion of magnesium, or anything else for that matter, represents a chemical change. For magnesium, the combustion reaction results in the loss of magnesium and the production of magnesium oxide. Clearly a chemical change.
The rate of heat loss from the hot cup change during the experiment answer?
The rate of heat loss from the hot cup decreased during the experiment.
Solid limestone may change into a cave when?
Solid limestone may change into a cave when it is dissolved by acidic rainwater or groundwater over long periods of time. The water dissolves the limestone, creating underground voids and passages that eventually form a cave system. Other factors like tectonic activity or volcanic activity can also contribute to cave formation in certain circumstances.
How does sulfuric acid react with limestone?
if limestone is in a solid form it would degrade (hence a loss in mass of the limestone) and carbon dioxide would be given off. if it is in the powdered form the change in mass would not be very obvious and only a loss carbon dioxide would be seen.
Is there a theory of loss and change?
can somebody tell me about loss and change theory.tnx
What are the sources of error in the experiment calorimetry measurement?
Energy loss due to leaks in the calorimeter
What are the sources of errors in the experiment of determine of enthalpy change of hydration of copper ii sulphate six?
heat loss to the surroundings if you using the simple 'insulated cup' method. Insufficient stirring, so that not all the solid is dissolved is another. A 'chemical' source of error is that the anyhydrous salt, which forms one half of the experiment, may not be completely anhydrous and will also absorb water from the air if left exposed for any length of time.
How does limestone affect monuments?
Limestone is primarily made of Calcium Carbonate which is a soluable in water and weak acid solutions. Anytime rainfall hits a monument made of limestone, it weathers it a bit faster than if it were made of marble.
How did the rate of heat loss from the hot cup change during the experiment?
The rate of heat loss from the hot cup likely decreased over time as the temperature of the cup approached that of the surroundings. Initially, when the cup was hot, the rate of heat loss would have been higher due to the temperature difference between the cup and the surroundings. As the cup cooled down and approached equilibrium with the room temperature, the rate of heat loss would have reduced.
If you heated limestone how would you expect the mass of the limestone to compare with the mass of calcium oxide?
When limestone is heated, it undergoes a chemical reaction that releases carbon dioxide gas, leaving behind calcium oxide. As a result, the mass of the limestone would be greater than the mass of the calcium oxide produced, due to the loss of carbon dioxide during the reaction.
Heat is eliminated during the process of freezing this loss of heat is considered what kind of change?
This loss of heat is considered a physical change.
What is a physical change in matter caused by a loss or gain of heat called?
A physical change in matter caused by a loss or gain of heat is called a thermal change.
What change is observe when a leave was boiled in warm water in a experiment?
