Answer:
V= 8.235 ml
Explanation:
The man above me copied me from the comments
I did it >:C
the balanced equation for the above reaction is as follows;
3NiCl₂ + 2K₃PO₄ ---> Ni₃(PO₄)₂ + 6KCl
stoichiometry of NiCl₂ to K₃PO₄ is 3:2
the number of NiCl₂ moles reacted - 0.0102 mol/L x 0.134 L = 0.00137 mol
according to molar ratio
if 3 mol of NiCl₂ reacts with 2 mol of K₃PO₄
then 0.00137 mol of NiCl₂ reacts with - 2/3 x 0.00137 = 0.000911 mol of K₃PO₄
molarity of given K₃PO₄ solution - 0.205 M
there are 0.205 mol in 1000 mL
therefore volume of 0.000911 mol - 0.000911 mol / 0.205 mol/L = 4.44 mL
volume of K₃PO₄ needed is 4.44 mL
Answer:
(A) those with atomic numbers from 93 to 118
Explanation:
got the answer from q**zlet. hope this helps :)
Surface area of the solid reactant,
concentration or reaction of reactant
temperature
nature of the reactants
presence or absence of the catalyst
The valence-shell electron-pair repulsion (VSEPR) theory states that electron pairs repel each other whether or not they are in bond pairs or in lone pairs. ... The shape of a molecule is determined by the location of the nuclei and its electrons
