Potassium carbonate is one of the chemicals left behind ... bonds are broken or formed as it takes place. But it generates heat, so can be described as exothermic. Although aqueous solutions ...

In their previous experiment, the team created calcium carbonate concrete by pouring a bicarbonate solution through carbonated concrete powder and heating it. In this updated version, as well as ...

If a compound is heated it will break down to two or more substances and these can be elements or compounds. So, if we have calcium carbonate and we heat it, it breaks down to produce calcium ...

It is then shaped and compressed so the calcium carbonate particles bond and solidify. Heat is applied in the final stage to complete the process. The scientists discovered that the concrete ...
