if 146.5 g of chromium chlorite decomposes, what mass of oxygen can be produced

calculate the molarity and the molality of an NH3 solution made up of 30g of NH3 in 70g water. The density of solution is .982g/ml.

two containers of the same volume contain respectively a sample of oxygen at 1.52*10^(5)Nm^(-2) and a sample of nitrogen at 1.01*10^(5)Nm^(-2), what will be the pressure if both gases are held in the same container at the same temperature

Write the structure of following compounds

2)1,3,5-trimethyl benzene

Matter is made-up of very small particles. It is arranged and move according to its

state and it has a different type. The arrangement and the motion of the molecules or

particles is affected by (1) of attraction. The London Dispersion Forces; it is the

(2) among the types. It is acting between (3) and (4) where a (5) moments

induced in ordinary (6) molecules. Another type is (7) Forces,

there is an attractive force between polar molecules, wherein the partial (8) side of a

molecule is attracted to a partial (9) side of another molecule. Next, the (10) ,

the hydrogen atom interacts with (11) or nitrogen or (12) atom to form polar

bond. Lastly is the Ion-Dipole Forces that shows the interaction between the ion, whether

(13) or (14) , and the polar molecules. It is most common found in

(15) . Note that these forces of attraction have different strength.
