Answer:
B. The bonds are polar and the molecule is nonpolar.
Explanation:
Each bond in the molecule is polar, as indicated by the partial charges on the atoms of the molecule. However, the four atoms are arranged symmetrically around the central atom. In this case, the effects of the partial charges on opposite sides cancel out. As a result, the molecule as a whole is nonpolar. If exposed to an electric field, the molecule will not orient itself in any particular direction.
Answer: B) explanation of why the pesticide is toxic to organisms.
Explanation:
Pesticide is a chemical or biological substance which is required to kill the population of pests and which are harmful and affecting the life cycle of the plants.
The structure of pesticide is required to be known so as to get information of the chemical or biological agent present in these pesticides. This can help in determining the fact that which ion or molecules directly cause harm to the body of pests by releasing the toxicity.
The scale is pH scale
- pH scale measures from 7
- pH>7 Basic
- pH<7 is acidic
- pH=7 is neutral
So
If pH tends to zero like 1 or 2 then it's highly acidic else weak acid
