(HELP PLEASE) which pair would have an electrostatic force of attraction between them?
NISA [10]

Answer: K+ and P 3−

Explanation:

Electrostatic force of attraction is the attraction between different molecules that comes from them being electrically charged.

For molecules to have an electrostatic force of attraction, they need to have opposing charges because like charges repel each other but opposite charges attract.

In the question above, the only option that has opposing charges is option D so this is the correct option.

A chemistry student needs 45.0mL of pentane for an experiment. By consulting the CRC Handbook of Chemistry and Physics, the stud
Masja [62]

The mass of pentane the student should weigh out is

The density of pentane is 0.626 gcm-3

To calculate the mass of pentane following expression is used,

(Density is defined as the mass divide by volume)

Density = mass / volume

mass of pentane = Density of pentane * Volume of pentane

mass of pentane = 0.626 gcm-3 * 45.0 mL

                             = 28.17 g

Here the unit of mass of pentane is g,

However the unit of density is gcm-3 and unit of volume is mL i.e. cm3

Hence,   Mass = gcm-3 * cm3

              Mass = g

The mass of pentane the student should weigh out is 28.17g
