Polyphosphate - an ancient energy source and active

There are a several molecules on Earth that effectively store energy within their covalent bonds, and one of these energy-rich molecules is polyphosphate. In microbial cells, polyphosphate granules are synthesised for both energy and phosphate storage and are degraded to produce nucleotide triphosphate or phosphate. Energy released from these energetic carriers is used by the cell for

What is the chemical equation for calcium and water? …

calcium react with water on contact, forming Calcium hydroxide (CaOH)2 and Hydrogen H2. the reaction gives off heat, but is a much slower reaction than other alkaline metals. from memory (I haven’t studied chemistry for 15 years!) The equation looks something like below: Ca + H2O > 2 CaOH + H2

This is in contrast with magnesium, immediately above calcium in the periodic table, which is virtually unreactive with cold water. The reaction forms calcium hydroxide, Ca(OH) 2 and hydrogen gas (H 2). The calcium metal sinks in water and after an hour or so bubbles of hydrogen are evident, stuck to the surface of the metal.
