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
Explanation:
mega=10raised to the power 6
kilo=10 raised to the power 3
centi = 10 raised to the power negative 2
Milli = 10 raised to the power negative 3
nano = 10 raised to the power negative 9
pico= 10 raised to the power negative 12
micro = 10 raised to the power negative 6
False , they form water or ice crystals
Explanation:
It should be decreasing, and the potential energy increasing, since Law of Conversation of Energy, right?
Also, if you think about what happens when it goes down, it loses potential and gains kinetic, so maybe the opposite should happen when it goes up.
