2h3po4 + 3mg(oh)2 → mg3(po4)2 + 6h2o phosphoric acid, h3po4, is neutralized by magnesium hydroxide, mg(oh)2, according to the eq
Rina8888 [55]
The balanced equation for the neutralisation reaction is as follows
2H₃PO₄ + 3Mg(OH)₂ --> Mg₃(PO₄)₂ + 6H₂O
stoichiometry of H₃PO₄ to H₂O is 2:6
number of H₃PO₄ moles reacted - 0.24 mol
if 2 mol of H₃PO₄ form 6 mol of H₂O
then 0.24 mol of H₃PO₄ forms - 6/2 x 0.24 = 0.72 mol of H₂O
therefore 0.72 mol of H₂O are formed

a chemistry teacher adds 50.0 ml of 1.50 m h2so4 solution to 200 ml of water. What is the concentration of the final solution?
nevsk [136]

Answer:0.300M

Explanation:1) Data:

a) Initial solution

M = 1.50M

V = 50.0 ml = 0.050 l

b) Solvent added = 200 ml = 0.200 l

2) Formula:

Molarity: M = moles of solute / volume of solution is liters

3) Solution:

a) initial solution:

Clearing moles from the molarity formula: moles = M × V

moles of H₂SO₄ = M × V = 1.5M × 0.050 l = 0.075 mol

b) final solution:

i) Volumen of solution = 0.050 l + 0.200l = 0.250l

ii) M = 0.075 mol / 0.250 l = 0.300M ← answeer

Which of the following best explains how the results of Rutherford’s experiment affected Thomson’s widely-accepted atomic model?
hichkok12 [17]

Explanation:

Thomson's suggested the plum pudding model of the atom in which the atomic space is made up of electrons surround by positive charges.

Rutherford in his gold foil experiment revised the plum pudding model of the atom;

  • He discovered that most of the alpha particles passed through the foil while a few of them were deflected back.
  • To explain this observation, he suggested the atomic model of the atom.
  • In this model, an atom is made up of a small positively charged center where nearly all the mass is concentrated.
  • Surrounding the nucleus is the extranuclear part made up of electrons.
