Answer:

True

Explanation:

Yes.

The distance that the molecules move depends on their solubility in the solvent and the size of the molecules. Heavy molecules will travel slower and therefore travel a shorter distance in the time the chromatography is run.

We know from such things as felt tip pens that colourings can be soluble in different solvents. Water soluble felt pens have colours that are - well - water soluble. Permanent felt pens have colours that are insoluble in water but that are soluble in another solvent. This could well be alcohol.

The water soluble colours may also be soluble in alcohol. The solubility in alcohol will be different from the solubility in alcohol, and so the Rf value ( the distance travelled) will also be different.

Because of the complicated shapes of the colours, the colours may not have the same order in the Rf values in the different solvents.

Find the volume of 2.40 moles of gas whose temperature is 50.0°C and whose pressure is 2.00 atm.

DanielleElmas [232]

PV=nRT
n=2.4 moles
T=273.15+50=323.15K
P=2*101325=202650 Pa
R=8.31

Solve for V:
V=nRT/P=2.4*8.31*323.15/202650=.032m^3

In matter results in a change in its identity and properties.

FrozenT [24]

Answer:

The chemical change in matter is results in a change in its identity and properties.

Explanation:

There are toe type of changes physical change and chemical change.

The chemical change change in matter lead to lost its identity and properties.

Chemical change:

The changes, that occur due to change in the composition of a substance and result in a different compound is known as chemical change.

These changes are irreversible

These changes occur due to chemical reactions

These may not be observed with naked eye

Example:

Combustion of fuel or wood: that oil or wood convert into energy, CO2 and ash in case of wood

Boiling of egg: that change the chemical composition of protein in the egg .

The reaction of Hydrogen and oxygen:

H 2 (g) + O 2 (g) -------------------------------------> 2H 2O (l)

Arrange the following in order of increasing bond strength of the carbon oxygen bond:

Brilliant_brown [7]

Answer:

The correct option is: Carbonate ion < Carbon dioxide < Carbon monoxide

Explanation:

Bond energy is defined as the average energy needed to break a chemical covalent bond and signifies the strength of chemical covalent bond.

The bond strength of a covalent bond depends upon the bond length and the bond order.

Carbon monoxide molecule (CO) has two covalent bond and one dative bond. Bond order 2.6

Carbon dioxide (CO₂) has two carbon-oxygen (C-O) double bonds of equal length. Bond order 2.0

Carbonate ion (CO₃²⁻) has three C-O partial double bonds. Bond order 1.5

Also, the bond length is inversely proportional to the bond order and bond strength.

Therefore, order of C-O bond length: Carbon monoxide<Carbon dioxide<Carbonate ion

Order of C-O bond order: Carbonate ion<Carbon dioxide<Carbon monoxide

Order of C-O bond strength or energy: Carbonate ion<Carbon dioxide<Carbon monoxide
