The main issues of using synthetic polymers include toxicity poor biocompatibility etc. Synthetic polymers stay non-degradable for ling time and make the surface polluted.
What are synthetic polymers?
Natural polymers are naturally made substances such as cellulose, starch, glycogen etc. Polymers made by man are called synthetic polymers. Synthetic polymers are diverse and are made through several polymerization techniques.
PVC, polyethylene, polyesters Teflon etc. are very common polymers in daily life. A major class of synthetic polymers include plastics which are major pollutants nowadays.
Most of the synthetic polymers are non-biodegradable and will cause landfill issues. Some them are toxic in nature and might cause several health issues. Blending them with biodegradable polymers is a solution for this.

The wavelength of the green light radiation that has a frequency of 6.26 x 10¹⁴ Hz is 4.8 x 10⁻⁷.
What is wavelength?
Wavelength is defined as the distance between identical points or adjacent crests in the adjacent cycles of a waveform signal propagated in the space or wires.
Frequency is defined as the number of waves that passes a fixed place in a given amount of time.
It is also defined as how often something repeats.
As, c = ∧ v
So, ∧ = c / v
∧ = 3.00 x 10⁸ / 6.26 x 10¹⁴
∧ = 4.8 x 10⁻⁷
Thus, the wavelength of the green light radiation that has a frequency of 6.26 x 10¹⁴ Hz is 4.8 x 10⁻⁷.
To learn more about wavelength, refer to the link below:
#SPJ2
So,
λ=(3.00 x 10^8)/(6.26 x 10^14)
Answer= 0.48 x 10^-7
Answers
Answer:
is formed of cation,
and anion,
Explanation:
Naming of the ionic compounds:-
- The name of the cation is written first and the the name of the anion is written after the name of the cation separated by single space.
- The negative ion is written next and a suffix is added at the end of the negative ion. The suffix written is '-ide'.
- In case of transition metals, the oxidation state are written in roman numerals in bracket in front of positive ions.
Hence, given ionic compound:-
is formed of cation,
and anion,
Thus, the name must be Cobalt(II) nitrate.

Answers
Marine west coast and Mediterranean are the types of temperate climates, due to the dispersion of precipitation throughout the year, temperate marine climates are typically distinguished by a notable lack of dry season, hence options D and E are correct.
What is temperate climates?
Temperate climates are regions with moderate annual or seasonal rainfall, intermittent drought, mild to warm summers, and cool to cold winters.
Humid subtropical, marine west coast, Mediterranean are the phrases that clearly identified with temperate marine climates.
Geographically speaking, the moderate climates of Earth are found in the middle latitudes, which are halfway between the tropics and the poles.
Therefore, options D and E are correct.

The answer I got was False, is this correct?
Answers
Answer: yes it is false
Explanation:
The statement is false. A synthetic process with a lower E-factor produces less waste than a process with a higher E-factor.
The E-factor is a measure of the waste generated during a manufacturing process. It is calculated by dividing the total mass of waste produced by the mass of the desired product. A lower E-factor indicates that less waste is generated per unit of product.
In this case, the synthetic process with an E-factor of 3.0 produces less waste than the process with an E-factor of 17.4. This means that the process with an E-factor of 3.0 is more efficient in terms of waste reduction.

Explanation:
Magnesium is the element of second group and third period. The electronic configuration of magnesium is - 2, 8, 2 or
There are 2 valence electrons of magnesium.
Only the valence electrons are shown by dots in the Lewis structure.
As, stated above, there are only two valence electrons of magnesium, so in the Lewis structure, two dots are made around the magnesium symbol.
Given that the electronic configuration is:- .
Orbital s cannot accommodate 3 electrons and also in magnesium it has . Hence, the statement is false.
