Answer:
A because ohc 3 stands for 1 that means one oxygen joint the h 6+6=12 so 1 oxygen and 12 hydrogen
Answer:
electron are on the outside of the nucleus and form rings
Explanation:
Answer:
0.85M
Explanation:
Given parameters:
Mass of CuCl₂ = 400g
Volume of water = 3.5L
Unknown:
Molarity of the solution = ?
Solution:
Molarity is one of the ways of expressing the concentrations of a solution. It is defined as the number of moles per unit volume of a solvent.
Molarity = 
To find the number of moles of CuCl₂;
Number of moles = 
Molar mass of CuCl₂ = 63.6 + 2(35.5) = 134.6g/mol
Number of moles =
= 2.97moles
Molarity =
= 0.85M
Answer:
The (H30+) is 4,13x10-8
Explanation:
We use the formula
Kwater = (H30 +) x (OH-)
1.00e-14 = (H30 +) x 2.42e-7
(H30 +) = 1.00e-14 / 2.42e-7 = 4.13e-8M
