What is the mass in grams of precipitate formed when 250.0 mL of
0.100 M ZnCl2 is mixed with excess
KOH in the following chemical
reaction?
ZnCI2 (aq) + 2 KOH (aq) → Zn(OH)2 (s)
+ 2 KCl (aq)

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.

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
