What has a greater boiling point elevation when dissolved at a concentration of 1mol in water with NaCl or MgCl2?
Kateruh
In the same volume of water, one mole of MgCl2 will give rise to a greater boiling point elevation. This is explained by the fact that boiling point elevation is a colligative property, that is, the relative amounts of the constituents are important and not their identity.
We can determine by inspection that, upon dissociation, more ions will be produced by MgCl2 than NaCl since there are more atoms in the MgCl2 molecule. So, for one mole of MgCl2, we will produce one mole of magnesium and two of chlorine (three total). For one mole of NaCl, we produce one mole each of potassium and chlorine. By employing the principle stated above, we can come to the correct conclusion.

How does the rate of salt dissloved be effected by temperature?
At higher temperatures a greater amount of salt can be dissolved. Therefore, if you use a boiling solution of water and dissolved salt until it is saturated, then let the solution cool down, the salt comes out of solution in the form of crystalisation.
What environment has the greater concentration of dissolved oxygen warm water or cool water?
You can't tell just from the temp - cool water is capable of dissolving more oxygen ... but that doesn't mean that it will (or does).
Diffusion is the movement of molecules from an area of?
...greater concentration to an area of lesser concentration.
What solution has a grater concentration h or OH?
Depends on the pH, at low pH (below pH 7), the H+ ion concentration is greater, and high pH the OH- ion concentration is greater
Which solute an electrolyte or a non electrolyte has the greater effect on the boiling point when a given amount of each solute is dissolved in the same mass of water?
The effect depends only on the concentration of solutes.
What brings greater concentration of dissolved nutrients to the ocean surface?
Upwelling
What is the effect of NaCl and CaCl2 on the boiling point of water?
The water with solved ions has greater boiling point. The dissolved salts increase the boiling point of water.
What is the solution concentration of dissolved substances will be greater in the cell than in the solution in which it is placed?
Hypotonic
What happens when the concentration of dissolved substances is greater outside the cell than inside?
Particles always move from an area of high concentration to an area of low concentration. Therefore, if the concentration of dissolved substances is greater outside the cell, they will travel into the cell until there is an equal concentration of the substance on both sides of the cell wall.
If a cell is placed in a what solution the concentration of dissolved substances will be greater in the solution than in the cell?
isotonic.
Which environment has the greater concentration of dissolved oxygen salt water or fresh water?
fresh water

What kind of environment is described when the concentration of dissolved substances is greater inside the cell or outside?
When greater than the cell it is hypertonic lower it is hypotonic
What solution is placed in the cell when the concentration of dissolved substances will be greater in the cell than in the solution in which it is placed?

Why does salt affect the boiling point of water?
Salt will increase the boiling point and decrease the freezing point of water due to colligative properties. Table salt (NaCl) breaks into ions when dissolved. This lowers the vapor pressure of water. When salt dissolves its ions are moving around in the water, and some are near the surface. Rather than all the water just boiling off, some of these ions get in the way, which will raise the boiling point. This effect is not only caused by salt, but by dissolved substance. In general, the more ions or particles dissolved, the greater the effect on boiling point, so MgCl2 would have a greater effect on boiling point than NaCl, because MgCl2 dissociates into three ions instead of two.
