Answer:
electrolysis is a technique that uses a direct electric current to drive an otherwise non-spontaneous chemical reaction
Explanation:
1 cup I believe is the right answer sorry if it’s not
Answer:Explanation:
The Roman numeral must have the same value as the charge of the ion. In our example, the transition metal ion Fe2+ would have the name iron(II). Add the name of the anion to the transition metal ion. In our example, FeCl2 would have the name iron(II) chloride since the anion is Cl-, which has the name chloride.
Answer:
ok so the answer is
4(energy)
5(kinetic energy)
6(potential energy)
7(gravity)
8(work)
Explanation:
I already learned this last year.
Answer:
Molarity = 54.50 M
Explanation:
Molarity is defined as the number of moles of a solute in 1 liter of solution. It has mol/l unit.
Molar mass of glucose, C6H12O6 = (6*12) + (1*12) + (16*6)
= 72 + 12 + 96 = 180g/mol
Density of glucose solution = 1.03g/ml
Density in g/l = 1.03g/ml * 1ml/10^-3l
= 1030g/l
10.5% mass of glucose = 10.5/100 * 180
= 18.9g/mol
Molarity = density (g/l)/molar mass (g/mol)
= 1030/18.9
= 54.50 M
