Answer:125ml - volume of phosphoic acid
Explanation:
The equation of the reaction is
H3PO4 + 3 NaOH ---> Na3PO4 + 3H2O
Such that I mole of H3PO4 reacts with 3 moles of NaOH to produce the products above.
Given that
M1= Molarity of phosphoric acid = 7.48x10^-2 M
n1= number of moles of phosphoric acid = 1
V1=? ml
M2= Molarity of Sodium hydroxide =0.244 M
V2= volume of sodium hydroxide= 115ml
n2=number of moles of sodium hydroxide = 3
Using the Dilution equation formulae,
M1V1/n1 = M2V2/n2
7.48X10-2 x V1 /1= 0.244M x 115ml/3
V1=0.244Mx115mlx1/0.0748M X 3
V1= 28.06/0.2244= 125.04ml
V1=125.04ml rounded up to 125ml
Answer:
Ba^2+ = Barium ion [Cation]
Cl-= Chloride ion [Anion]
Explanation:
Ba(OH)2 + HCl = BaCl2 + H2O is the reaction that happens.
You make an ionic compound which is soiuble in water Barium Chloride. The cation is Ba^2+ = Barium ion, Cl^ - = Chloride ion
Postive ions are cations and negative ions are anions thus
Ba^2+ = Barium ion [Cation]
Cl-= Chloride ion [Anion]
Answer:
KCl ⇒ 1.205x10²⁴ molecules
O₂ ⇒ 1.807x10²⁴ molecules
KClO₃ ⇒ 1.205x10²⁴ molecules
Explanation:
In order to calculate the number of particles from the number of moles, we have to use Avogadro's number, which states <em>the number of particles in one mol</em>:
- In 1 mol there are 6.023x10²³ particles (ions, molecules or atoms).
So now we <u>multiply the number of moles of each substance by Avogadro's number</u>:
- KCl ⇒ 2 mol * 6.023x10²³ molecules/mol = 1.205x10²⁴ molecules
- O₂ ⇒ 3 mol * 6.023x10²³ molecules/mol = 1.807x10²⁴ molecules
- KClO₃ ⇒ 2 mol * 6.023x10²³ molecules/mol = 1.205x10²⁴ molecules
