Bleaching powder is synthesized by the action of chlorine gas (produced from the chlor-alkali process) on dry slaked lime (Ca(OH)2).

Ca(OH)2 + Cl2 → CaOCl2 + H2O

Explanation:

   Bleaching powder is a pale yellowish powder existing with a strong smell of chlorine.

   It is soluble in water but due to the presence of impurities, we never observe a clear solution.

   Its chemical formula is CaOCl2 with its chemical name as Calcium hypochlorite.

Calcium hypochlorite

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z

answer

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
