X of moles/2.5L =0.50 M NaCl solution
X of moles = 2.5 * 0.5
X = 1.25 moles
Rounding with significant digits
1.3 mol
The correct answer is B.
Lowering of the freezing point can be a colligative property. The greatest concentration of mass of salt in the water will have what we call the lowest freezing point.
For example the least amount of water in the greatest amount of salt.
The Stereo microscope, also called a dissecting microscope, has two optical paths at slightly different angles allowing the image to be viewed three-dimensionally under the lenses. Stereo microscopes magnify at low power, typically between 10X and 200X.
So Helium walks into a bar and orders a beer...
The bartender says, "Sorry we don't serve noble gases here."
Helium doesn't react.
Minerals
Explanation:
Minerals in solution crystallizes and settles out of a solution. Chemical sediments are products of chemical weathering of rocks.
- During chemical weathering, pre-existing rock materials are decomposed.
- These materials are then carried as dissolved loads during erosion and transportation.
- When these minerals come in contact with favorable environment, they precipitate out and forms chemical sediments.
- Examples of rocks that results from chemical sediments are rock salt, evaporites, dolomite e.t.c
