Answer:
We can obtain sugar crystals from the sugar solution,without losing ethanol by warming a bowl of water. Putting sugar in it till it dissolves. And then leave it to cool with a string at its mouth. When the water cools sugar crystals accumulate in the string thus without losing ethanol.
B) Repeated experiments that show the same results are less likely to contain experimental errorli
Answer:
Molarity of Ba²⁺ is 0M
Explanation:
Some barium ion, Ba²⁺ is produced when barium acetate is dissolved (Moles of barium acetate = moles of Ba²⁺ in solution). Then, Ba²⁺ reacts with sulfate ion to produce BaSO₄, an insoluble salt. The concentration of Ba²⁺ is the initial concentration - the concentration of SO₄²⁻ in solution.
Initial moles of Ba²⁺:
Moles barium acetate (Molar mass: 255.43g/mol)
0.363g * (1mol / 255.43) = 1.421x10⁻³ moles of Ba²⁺
Moles SO₄²⁻ = Moles of ammonium sulfate:
100mL = 0.100L * (0.025mol / L) = 2.5x10⁻³ moles of SO₄²⁻.
As moles of SO₄²⁻ are higher than moles of Ba²⁺, Molarity of Ba²⁺ is 0M because all moles of Ba²⁺ reacts producing BaSO₄(s), an insoluble salt.
Answer:
cation
Explanation:
An atom that has lost an election becomes a positively charged ion and it's called a<em> </em><em>cation</em>
