<span>Eventually the increase in water may cause the blood cells to burst (cytolysis.) In a hypertonic solution, the concentration of dissolved solutes is greater than that of the cell. ... If the salt solution outside is 20% salt, then the water concentration is 80%.
The red blood cells will shrink in size due to osmotic-like pressure differences until it reaches a "favorable" size.</span>
Well there are 60 seconds in a minute and 60 minutes in an hour and 24 hours in a day so you would do 60×60 which is 3600. then you would multiply 3600 by 24 which would give you the number of seconds in a day, 86400. since you need the number of seconds in 2 days just multiply the amount by 2. your answer is: There are 172,800 seconds in two days.
Answer:
It’s true
Explanation:
If we account for all reactants and products in a chemical reaction, the total mass will be the same at any point in time in any closed system. ... The Law of Conservation of Mass holds true because naturally occurring elements are very stable at the conditions found on the surface of the Earth.
Formula: molality, m = n solute / kg solvent
n solute = # of moles of solute = mass(g) / molar mass
Molar mass of Mg Br2 = 184.11 g/mol
m = [46g / 184.11 g/mol] / 0.5 kg = 0.50 mol/kg
2 CuO (s) + C (s) -> Cu (s) + CO2 (g) Im not sure if that's it but yeah
