4. If 14.7 g of calcium is placed in 11.5 g of water, what mass of hydrogen gas is produced?
__ Ca + __ H2O → __ Ca(OH)2 + __ H2
please show work

Deposition is the transition of matter going from gas to solid without passing through the liquid phase.a.) gas—-> solid

Hcn is your answer my guy : )

Electron equations of the given changes are as follow,a)                              cu      →      cu⁺²  + 2e⁻b)                              mg⁺²  +  2 e⁻      →      mgc)                              cl⁻    →      cl  +  1e⁻d)                              s  +  2 e⁻    →      s²⁻e)                                o²⁻      →      o  +  2 e⁻f)                              p  +  3 e⁻    →      p³⁻g)                              fe²⁺    →      fe³⁺  + 1 e⁻h)                              s²⁻    →      s⁴⁺  +  6 e⁻

Ive had this before. your answer would be d. hope this ya
