Answer:
Biologist Rachel Carson made the world aware of the ecological effect of chemical composts and pesticides. Her most popular book, Silent Spring, prompted a presidential commission that generally embraced her discoveries and assisted with molding a developing ecological awareness.
Carson was not against the utilization of synthetic fertilizers or chemicals completely; rather, she thought the overuse was pushing their abuse for its financial increase, to the detriment of the health of the environment.
All individuals have the right to inhale clean air and to be liberated from the danger of poisoning due to chemicals; in this manner, all Americans likewise have an obligation to ensure that the earth is safe and clean.
The atom positions in a general molecule of formula (not shape class) AXn that has shape square pyramidal at the corers of square and one at the above center of the square.
<h3>What is square pyramidal?</h3>
The square pyramidal is a shape geometry of the hybridization in which it consists of one lone pair and 5 bond pairs of electrons that repel each other and due to which the geometry changes from octahedral to square pyramidal.
As atoms are located at the four corners of the planer and one atom at the above center of the planner which is repelled by 4 atoms present at the corner of the planer.
Therefore, the atom positions in a general molecule of formula (not shape class) AXn that has a shape square pyramidal at the corners of the square and one at the above center of the square.

<u>Answer:</u> 6.57 L of solution can be made.
<u>Explanation:</u>
Molarity is defined as the amount of solute expressed in the number of moles present per liter of solution. The units of molarity are mol/L. The formula used to calculate molarity:
.....(1)
Given values:
Molarity of LiBr = 3.5 M
Moles of LiBr = 23 moles
Putting values in equation 1, we get:
Hence, 6.57 L of solution can be made.
Different isotopes have different "Mass" numbers.
