dt = kf(im)
0.225 = kf(2(0.100m)
0.225 = kf(0.2)
0.225/0.2 = [kf(0.2)]/0.2
1.125 = kf
osmotic pressure=CRT x i 25 C to Kelvin = 298K 0.318atm= 0.010 M x 0.08206 x 298 K answer= 1.30
0.02/5=0.004
You mean solution right, not solutipon? lolIt is called the van't Hoff factor (i)
0.2 N HCl solution means 0.2 equivalents of HCl dissolved in 1 litre of water. Normality = Molarity x n-factor => Molarity =Normality/n-factor=0.2/1=0.2 M 0.2 moles should be present in 1 litre of solution. 0.2moles =0.2 x 36.5 = 7.3 grams of HCl =>Dissolve 7.3 grams of HCl in 1 litre if water to get a 0.2N solution.
There is a possibility that electronegativity can determine the activity series. This activity could knock ions out of solution and ranking in a series.
The temperature factor increases to 1.1547, approx.
Depression is a risk factor for stroke but depression does not cause stroke per se.
When people don't try and help, that is probably a big factor as why depression could be a cause of suicide.
The factor that helped worsen the Great Depression was the Smoot-Hawley Act.

yes

The dustbowl is a nickname for the Midwest during the great depression. I is one factor that causes the great depression because of the shortage of food.
No but it is a factor of 2460

Its not exactly the metal but the metallic salt in general. in general chemistry, the van't hoff factor for that compound will affect the rate at which the melting point of the ice will decrease. the salts, such as calcium chloride, lower the melting point of ice by a certain degree related to its specific van't hoff factor. usually, a common trick is to use the number of atoms involved in the salt to approximate its factor. For example, calcium chloride, or CaCl2, has three atoms in it. So its factor is about three. This is all related to freezing point depression (courtesy of wikipedia):ΔTf = Kf · mB where * ΔTf, the freezing point depression, is defined as Tf (pure solvent) − Tf (solution), the difference between the freezing point of the pure solvent and the solution. It is defined to assume positive values when the freezing point depression takes place. * Kf, the cryoscopic constant, which is dependent on the properties of the solvent. It can be calculated as Kf = RTm2M/ΔHf, where R is the gas constant, Tm is the melting point of the pure solvent in kelvin, M is the molar mass of the solvent, and ΔHf is the heat of fusion per mole of the solvent. * mB is the molality of the solution, calculated by taking dissociation into account since the freezing point depression is a colligative property, dependent on the number of particles in solution. This is most easily done by using the van 't Hoff factor i as mB = msolute · i. The factor i accounts for the number of individual particles (typically ions) formed by a compound in solution.
The greatest factor of 40 is itself
