How does increasing the concentration of a nonvolatile solute in water affect the following properties:Vapor pressure: Decreases

PIT_PIT [208]

Answer: Osmotic pressure : increases

Explanation:

Osmotic pressure is the minimum pressure which is applied to a solution to prevent the flow of solvent across a semipermeable membrane

$\pi =CRT$

$\pi$ = osmotic pressure

C= concentration in Molarity (number of moles of solute dissolved per liter of the solution)

R= solution constant

T= temperature

Thus as osmotic pressure is directly proportional top concentration, osmotic pressure will increase on increasing the concentration of a nonvolatile solute in water.

If the last carbon atom of an unsaturated fatty acid is bonded to two hydrogen atoms and one carbon atom, what type of bond must

Debora [2.8K]

Answer:

Double bond

Explanation:

Carbon is a tetravalent atom. This implies that the carbon atom always forms four covalent bonds.

These four covalent bonds may be single, double or triple bonds. Compounds that contain double and triple bonds are said to be "unsaturated".

If the last carbon atom of an unsaturated fatty acid is bonded to two hydrogen atoms and one carbon atom, it means that the bond between the last carbon and the other carbon atom must be a double bond because carbon must be tetravalent and we have already been told that the fatty acid is unsaturated.

The last carbon atom of the unsaturated fatty acid must form two covalent bonds to the other carbon atom in order to respect the tetravalency of carbon.

Consider the following reaction. SO2Cl2 → SO2 + Cl2. After collecting experimental data you found that plotting ln[SO2Cl2] vs. t

Nikitich [7]

Answer:

$[SO_2Cl_2]_{600}= 0.0842 M$

Explanation:

Some theoretical knowledge is required here. We should understand that whenever we plot the natural logarithm, ln, of a concentration vs. time and obtain a straight line, this indicates a first-order reaction. That said, since this is the case here, we have a first-order reaction with respect to $SO_2Cl_2$ .
