Sidewalk chalk is made from calcium and sulfate, which makes calcium sulfate. One of the most common chemicals connected to calcium is called “carbonate”, and together they make calcium carbonate.

When research on an intriguing material called for hundreds of samples, secondary-school students, teachers and technicians stepped up.

Found all over the world, calcite is the most stable form of calcium carbonate and is the main mineral found in limestone.

So how can a chick have enough strength to break out of its shell? The egg is a closed environment that allows the ...

There are several types of calcium, including calcium carbonate, calcium citrate, and calcium gluconate. Each type has different absorption rates and may be more suitable for certain individuals ...

Billions of years ago, Earth was home to extreme environments, including intense UV radiation, frequent volcanic eruptions, ...

In this reaction we will investigate the reaction between ethanoic acid and calcium carbonate. All acids produce carbon dioxide gas when reacted with a metal carbonate.

So, if we have calcium carbonate and we heat it, it breaks down to produce calcium oxide and carbon dioxide. Gethin: OK, I know you're poised with your pen and your flip chart. But, before that ...
