What different solutions can cells be in and what happenes to them?
There are three different types of solutions you can place a cell in: hypotonic (concentration of solution less than concentration of cell), isotonic (equal concentrations) and hypertonic (concentration of solution greater than concentration of cell). In a hypotonic solution, the cell will accumulate water (in an attempt to equalize the concentration difference) and will eventually rupture from the water pressure inside the cell. In an isotonic solution, the cell will do nothing. In a hypertonic solution, the cell will shrivel as the water exits the cell to dilute the solution to the same concentration as the cell. This will cause the cell to die.
A solution is prepared by mixing 360.0 mL of 0.25 M NaOH with 140.0 mL of 0.50 M NaOH and the final concentration is?
The concentration is 12,8 g/L NaOH.
What is a solution that has a lower solute concentration and a higher water concentration then another solution?
Hypotonic is the term describes a solution that has a lower solute concentration and higher water concentration than another solution Hypertonic describes a solution with a higher solute concentration compared with another solution.

Is hydrochloric concentrated acid?
Any concentration is possible to be prepared; the concentrated acid has generally a concentration of 36,5 % (36,5 g HCl in 100 mL water solution).
How do changes in concentration affect solutions?
it might have a different solution
Difference between primary standard solution and a secondary standard solution in acid-base titration?
primary standard solution is prepared by direct measurements of the mass of solute and the volume of solution.whereas, a secondary standard solution is a solution whose concentration can't be determined directly from weight of solute and volume of solution, the concentration must be determined by analysis of the solution itself.

How many moles of NF are dissolved in 4 L of a solution that has a concentration of 4 M?
Theoretically 16 moles but nitrogen monofluoride is unstable and I suppose that this solution cannot be prepared.
