used as a cleaning agent or an additive during clothes washing. The basic test for the presence of carbonate salts is a reaction with a diluted acid solution that leads to release of bubbles of the gas carbon dioxide and follows
How can you make calcium carbonate? How is sodium formed? What is the chemical name of NaHCO3? What is the common name for potassium bicarbonate? What chemical test could be used to identify limestone? What are the chemical properties of soda ash?

It was found that the alkali–silica reaction (ASR) due to cryptocrystalline quartz hidden in the matrix, always associated with dedolomitization in all the carbonate aggregates tested, was responsible for the expansion of both the laboratory and field concretes, even with the Canadian dolomitic ...
The “dead” in Deadlift stands for dead weight. So every rep must start on the floor, from a dead stop. You don’t Deadlift top-down like on the Squat or Bench Press. You start at the bottom, pull the weight up and then return it to the floor. Here are the five steps to Deadl...
