What has a greater boiling point elevation when dissolved at a concentration of 1mol in water with NaCl or MgCl2?
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.

Will elevation in boiling point be same for 0.1 m NaCl and 0.1m sucrose solution?
No, the elevation in boiling point will not be the same for a 0.1 m NaCl solution and a 0.1 m sucrose solution. This is because the elevation in boiling point is directly proportional to the number of particles in the solution, known as the van't Hoff factor. NaCl dissociates into two ions (Na+ and Cl-) in solution, so it has a van't Hoff factor of 2, while sucrose does not dissociate and has a van't Hoff factor of 1. Therefore, the NaCl solution will have a greater elevation in boiling point compared to the sucrose solution.

Why does tap water evaporate faster than saltwater?
Adding a solute to water will raise its boiling point, meaning you need to heat the water to a greater temperature in order to make it boil. Boiling point is a colligative property, meaning the number of solute molecules will affect the temperature at which it boils.
Is the lower the molarity the higher the concentration or the lower the molarity the lower the concentration?
The lower the molarity, the lower the concentration. Molarity is a measure of the concentration of a solute in a solution. A lower molarity means there is less solute dissolved in the solution, resulting in a lower concentration of the solute.
What environment has the greater concentration of dissolved oxygen warm water or cool water?
Cool water typically has a greater concentration of dissolved oxygen than warm water. This is because oxygen dissolves better in colder water than in warmer water. Oxygen levels in water are important for supporting aquatic life and ecosystems.
What brings greater concentration of dissolved nutrients to the ocean surface?
Upwelling
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?
An electrolyte has a greater effect on the boiling point compared to a non-electrolyte when dissolved in water. This is because electrolytes break into ions in solution, increasing the number of particles and thus raising the boiling point more significantly through colligative properties compared to non-electrolytes which do not dissociate into ions.
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.
What is the effect of NaCl and CaCl2 on the boiling point of water?
Adding NaCl (table salt) or CaCl2 (calcium chloride) to water raises the boiling point of water. This is due to the phenomenon of boiling point elevation, where the presence of solute particles in water disrupts its ability to form vapor, requiring higher temperatures to boil.
Will elevation in boiling point be same for 0.1 m NaCl and 0.1m sucrose solution?
No, the elevation in boiling point will not be the same for a 0.1 m NaCl solution and a 0.1 m sucrose solution. This is because the elevation in boiling point is directly proportional to the number of particles in the solution, known as the van't Hoff factor. NaCl dissociates into two ions (Na+ and Cl-) in solution, so it has a van't Hoff factor of 2, while sucrose does not dissociate and has a van't Hoff factor of 1. Therefore, the NaCl solution will have a greater elevation in boiling point compared to the sucrose solution.
What is the solution concentration of dissolved substances will be greater in the cell than in the solution in which it is placed?
The solution concentration of dissolved substances will be greater inside the cell than outside if the cell is in a hypertonic solution. This causes water to move out of the cell, leading to shrinkage or crenation of the cell.
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?
Suger
What happens when the concentration of dissolved substances is greater outside the cell than inside?
Water will move out of the cell in an attempt to equalize the concentration of dissolved substances, causing the cell to shrink or shrivel up. This process is known as crenation, and can have negative effects on the cell's functioning.
Which environment has the greater concentration of dissolved oxygen salt water or fresh water?
Freshwater typically has a greater concentration of dissolved oxygen compared to saltwater because oxygen dissolves more easily in freshwater due to its lower salinity. Ocean water is less oxygenated because it has a higher concentration of salts, which can make it more challenging for oxygen to dissolve.
Does salt affect the boiling point of water and why?
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.
What is the difference of boiling points between sea water and normal water?
Sea water has a higher boiling point than water, meaning that it will have to be heated more then pure water to boil. This temperature depends on the concentration of the salt in the salt water. The boiling point of normal water at normal pressure is 100C/212 F while for sea water it is 2 C higher or more depending on the salt concentration/impurities in the sea water. The difference in the boiling points would be 2 C or greater.
