The first 'reaction' that we tried for our hand warmer involved dissolving potassium carbonate (K 2 CO 3) in water. Potassium carbonate is one of the chemicals left behind in the ashes of burnt wood.

Stanford researchers developed a scalable method to permanently remove CO2 from the atmosphere using heat-activated minerals.

Spreading crushed rocks on fields can absorb CO2 from the air – now chemists have devised a way to turbocharge this process ...

Sodium carbonate may cause skin and serious eye irritation ... Explain that “soap scum” is a common example of a precipitate that forms when certain minerals in water react with soap molecules. Tell ...

Stanford University chemists have developed a practical, low-cost way to permanently remove atmospheric carbon dioxide, the ...

Metals, bases, certain metal hydroxides and certain metal carbonates, are insoluble in water ... that the reaction stops fizzing. You filter the mixture to remove the excess base/carbonate ...

A University of Nebraska-Lincoln research team has identified new microscopic players in the global carbon cycle, a discovery ...

Editor Lab results on drinking water samples taken in Savage show a chemical reaction is to blame for the residue problems residents reported after the city started buying ...

Students will be able to make measurements showing that whether the process is a change of state, dissolving, or a chemical reaction, the total mass of the substances does not change. Note: In the ...

Asteroids that orbit close to the Earth inevitably cause us some anxiety due to the even remote possibility of a collision.
