P2O5(s)+ H2O(l) -> diphosphorus pentoxide sizzled when came in contact with water, blue litmus turned red. H2O(l)+Ca(s) -> Calcium bubbles in the water, leaving a white powder at the bottom of the beaker. Mg(s)+H2O(l) -> Turns a light clear yellow (indicator) heat changes the color to blue, unheated turns the color to purple. 2HCL(aq)+Mg(s) -> H2(g) +...
