Correct 2 Ca + O2 ------> 2CaO
calcium oxide, CaO
Hydrogen gas is released when calcium and water react.
Calcium reacts with hydrochloric acid to produce Calcium chloride and hydrogen gas.Ca +2 HCl -----> CaCl2 + H2
It turns a bright red color and it does not spread. If you take a little bit of calcium and put in a bowl and light it up, it will crete a small fire in the bowl but it will not burn it.
It burns with a brick red flame and a white ash of calcium oxide reacts exothermically with water to form basic calcium hydroxide.
calcium oxide, CaO
Hydrogen gas is released when calcium and water react.
The two outer shell electrons of a calcium atom are donated to an oxygen atom, forming calcium cations and oxygen anions that together constitute the salt compound calcium oxide.
calcium oxide (quick lime) produces calcium hydroxide (slaked lime) when reacts with water.
Calcium reacts with hydrochloric acid to produce Calcium chloride and hydrogen gas.Ca +2 HCl -----> CaCl2 + H2
Calcium reacts with fluorine to form calcium fluoride (the symbol is CaF2).
the outer cell will burn up leaving calcium-oxide
3Ca + N2 = Ca3N2
it depends what acid, but generally it would produce carbon dioxide, water, and a calcium salt.
A good one A good one
It turns a bright red color and it does not spread. If you take a little bit of calcium and put in a bowl and light it up, it will crete a small fire in the bowl but it will not burn it.
The component of vinegar that reacts with the calcite is acetic acid. The acid reacts with calcium carbonate to produce water, carbon dioxide, and calcium acetate.
