The polyatomic nitrate ion (NO3−) is present in both the products and the reactants of the chemical equation shown below. Ba(NO3)2 + 2LiOH → Ba(OH)2 + 2LiNO3 How many nitrate ions are in the products and the reactants of the chemical equation?

b is the correct answer

mark me brainliest and hope this

the answer would be b i believe

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
