Answer:
85.8 g
Explanation:
The molar mass of BaCl₂ is 208.233 g/mol, so 210.1 g is about ...
210.1/208.233 ≈ 1.009 mol
The molar mass of K is about 39.089 g/mol, so 45 g is about ...
45/39.089 ≈ 1.1509 mol
The balanced equation seems to be ...
BaCl₂ + 2K ↔ 2KCl + Ba
This reaction requires 2 moles of potassium for each mole of barium chloride, so the available potassium limits the reaction. The result is as many moles of potassium chloride as there are moles of potassium.
The 1.1509 moles of KCl, at 74.551 g/mol will have a mass of about 85.8 g.
The reaction produces 85.8 g of KCl.
Answer: Do you take Ms. Reyes
Explanation: The answer is Outside air, Nose, Lungs, Bloodstream, Cell
Answer: it will increase the strong nuclear force in the nucleus
Explanation: Labster
The charge on one mole of electrons = 96485 C = 1 Faraday
so if charge is 96485 C the moles of electrons are 1 = 6.023 X 10^23 electrons
if charge is 1 C the number of electrons = 6.023 X 10^23 / 96485
If charge is 50 micro C the number of electrons
= 6.023 X 10^23 X 50 X 10^-6 / 96485
= 3.12 X 10^14 electrons
A is the correct answer. A combustion reaction creates carbon dioxide and water. A is the only answer choice were carbon dioxide and water are made.
