What type of reaction is limestone when heated?

Heating of limestone is a decomposition reaction as limestone decomposes to give calcium oxide and carbon dioxide.

Yes it is i have a friend who is allergic reaction to limestone dust


Is limestone affected by wind?

It does not have a reaction!!


How is limestone affected by hail?

No reaction!


If limestone was crushed what would it do to the rate of reaction between an acid and the limestone?

Crushing limestone would increase the surface area available for the acid to react with, thus increasing the rate of reaction between the acid and the limestone. This is because more particles of limestone would be exposed, allowing for more frequent collisions with the acid molecules.


What is the word equation for the reaction of dilute hydrochloric acid and limestone?

The word equation for the reaction of dilute hydrochloric acid and limestone is: hydrochloric acid + calcium carbonate (limestone) -> calcium chloride + carbon dioxide + water.


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.


What reaction creates topography?

Carbonic acid with limestone


How do you know that the decomposition of limestone is an endothermic reaction?

Endothermic means that a reaction needs heat to occur. Limestone needs to be heated to decompose into calcium oxide and carbon dioxide


Does sodium sulphate damage limestone?

Yes, sodium sulfate can react with limestone and cause damage over time due to sulfation reaction. This reaction can lead to the formation of gypsum, which can then cause cracking and deterioration of the limestone surface.

What type of rection is taking place when limestone is heated?

When limestone is heated, a chemical reaction called thermal decomposition occurs. This leads to the breakdown of limestone into calcium oxide (quicklime) and carbon dioxide gas.
