So Na + H2O + Aq = NaOHAq + H tells that certain masses of sodium and water
interact to produce certain masses of sodium hydroxide ( which is dissolved in
the excess of water ( s . ante par . 56 ) ] and hydrogen , and that the sum of the ...

When water is poured on to the compound calcium oxide , or lime , the water
disappears , the lime swells up , much heat is produced , and the new compound
calcium hydroxide , or slaked lime , is formed . The equation CaO + H 99 - 103 ...

When the solid compound calcium hydroxide is strongly heated — say to 400° or
500° — it is decomposed into calcium oxide and water ; thus CaO . HO = CaO +
H , O ; the water passes away and the calcium oxide remains as a solid . Copper

We have learned that when sodium and water interact the products are hydrogen
and sodium hydroxide ; the equation Na + H2O + Aq = NaOHAq + H expresses
the composition of the system before and after this interaction . A similar change ...
