The most likely reason powdered limestone reacts faster is that it has a larger surface area compared to larger pieces of limestone. This increased surface area allows more of the limestone to come into contact with reactants, facilitating quicker chemical reactions. Additionally, the finer particles can more easily penetrate and disperse in the reacting medium, further enhancing the reaction rate.
Sodium is a metal that reacts quickly with cold water only when it is finely powdered. When the surface area of the sodium is increased by grinding it into a fine powder, it can react with the water at a faster rate due to the increased contact between the metal and the water molecules.
Carbon dioxide reacts with water to form carbonic acid, which can dissolve limestone over time. This process is known as carbonation and results in the breakdown of limestone through chemical weathering.
Carbon dioxide reacts with water to form carbonic acid, which then reacts with minerals in rocks like marble and limestone, causing them to dissolve. This is known as carbonation weathering and is a common process in the dissolution of carbonate rocks.
Powdered magnesium has a greater surface area compared to a strip of magnesium, which allows for more contact with the reactant, such as oxygen from the air. This increased surface area results in a faster reaction rate, as more magnesium atoms are available to react at the same time.
Limestone is a basic rock that can neutralize acid rain, whereas granite is an acidic rock that can make bodies of water more susceptible to acidification. When acid rain reacts with limestone, it forms less harmful compounds than when it reacts with granite. This difference in buffering capacity helps lakes with limestone beds to experience less adverse effects from acid rain.
o
exothermic process takes place when powdered limestone reacts with acid in lakes.
potassium permanganate reacts with powdered sugar
it is a neautralisation reaction. i just got that exact same question in my AQA science workbook > <
Powdered zinc has a larger surface area compared to large pieces, allowing for a higher rate of reaction with the hydrochloric acid. The increased surface area exposes more zinc atoms to the acid, leading to faster hydrogen gas production.
When limestone reacts with acid, Carbon Dioxide is produced.

Sodium is a metal that reacts quickly with cold water only when it is finely powdered. When the surface area of the sodium is increased by grinding it into a fine powder, it can react with the water at a faster rate due to the increased contact between the metal and the water molecules.
The colorless mineral you're referring to is likely calcite. When powdered calcite is combined with acid, such as hydrochloric acid, it reacts to produce carbon dioxide gas, which causes the characteristic bubbling or fizzing. This reaction is a key identification test for calcite in mineralogy. Its colorless form is often found in sedimentary rocks like limestone.
Limestone
Limestone tends to decay faster from acid rain compared to granite. This is because limestone is composed mainly of calcium carbonate, which easily reacts with the acid in rainwater. Granite, on the other hand, contains minerals that are more resistant to acidic corrosion.
Powdered flour reacts more quickly than lumps of wheat because it has more surface area to absorb liquid.
