WHAT IS the density at 27degrees celsius of 30ml of a. liquid that has a mass of 2.6g?

The answer is

Explanation:

The density of a substance can be found by using the formula

From the question

mass of liquid = 2.6 g

volume = 30 mL

The density is

We have the final answer as

Hope this helps you

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.

one negative thing it that it can kill water animals. another negative thing is it can cause the destruction of ecosystem. one way water pollution can be reduced is to conserve energy.
