b. planting replacements
c. clearcutting
d. soil maintenance

Answers

Answer 1
Answer: The correct answer for the question that is being presented above is this one: "c. clearcutting." Clearcutting, clearfelling, or clearcut logging is a forestry/logging practice in which most or all trees in an area are uniformly cut down. Clearcutting in itself is not an effective way to manage forests and trees.

Potassium has nineteen protons. how many electrons does a neutral potassium atom have? a. 0
b. 17
c. 19
d. more information is needed to figure this out.

Answers

Answer:

c. 19

Explanation:

Potassium is a chemical element of the periodic table whose chemical symbol is K, whose atomic number is 19. It is an alkaline metal of white-silver color, which abounds in nature in the elements related to salt water and other minerals. It oxidizes rapidly in air, is very reactive, especially in water, and chemically resembles sodium. It is an essential chemical element.

The K having an atomic number of 19 means that it has 19 protons and in normal conditions for a neutral atom it will have 19 electrons, and being one step away from argon gas makes it extremely unstable.
It has 19 electrons. I hope this helps.

How many oxygen atoms are in the compound Al2O3?

Answers

As you know, the symbol of the Oxygen is "O"
And in a compound's empirical formula (In this case Al2O3), the number after each Symbol is how much atoms of this kind there is.

So, There is 3 Oxygens atoms in the Aluminium Oxide Al2O3

Hope this Helps :)
