A) Head to tail joining of monomers. :) (confirmed correct answer, I took the test)
The maximum number of electrons:
- s sublevel: 2 electrons,
- p sublevel: 6 electrons,
- d sublevel: 10 electrons,
- f sublevel : 14 electrons.
sodium hydroxide (NAOH) a.k.a causic soda commonly used in labs.
- MOLAR MASS of naoh is 39.997 g/mol.
- It is dry hard brittle, white stocks in large fused opaque white-stone like masses having a dense crystalline fracture in small pellets/flakes.
- it is very delinquent and one of the strongest base , acts as a saponifying agent which is used in industrial purposes.
- It is an important industrial chemical as it is used on its own and is also used as a raw material in the production of other chemicals. The basis for the production of sodium hydroxide is the electrolysis of brine.

Poor water quality has its most direct impact on aquatic wildlife. Such as fish, bugs, and plants
Answer:
3.077 × 10¹⁴ Hz
Explanation:
f = ?
wavelength = 9.75 × 10-⁷m
using the formula,
c = wavelength × frequency
f = c/wavelength
but c(speed of light) = 3×10⁸m/s
f = 3 × 10⁸/9.75 × 10-⁷
f = 3.077 × 10¹⁴ s-¹
