Answer:
21.8
Explanation:
add both because there both forces are going down
Almost 30 years after the clean water act was passed in the US, the percentage of surface water considered safe for fishing and swimming had increased from 36% to 60% which is almost twice the original value. Certain programs and policies were implemented as part of the act.

2.) present at conferences
3.) present at universities
4.) inform popular media’s
5.) show data
6.) show hypothesis
7.) and give a theory
Answer:
Yes
Explanation:
It is possible that a non polar molecule contain polar bonds.
Consider the example of CO₂:
In carbon dioxide the atoms are arranged in angle of 180 degree and molecule is linear. So in this way the net dipole movement becomes zero and molecule is non polar.
But when we see the electronegativity of both bonded atoms the oxygen is more electronegative than carbon. The oxygen atom have partial negative charge and carbon have partial positive charge because shared pair of electron is more attracted towards the oxygen. Thus bond become polar because one end is partial positive and other is partial negative. Thus a non polar carbon dioxide molecule have polar bond.
