23.22%:
2.5 L in mL : 2.5 * 1000 = 2500 mL
23.22 g ----------- 100 mL
? g ------------- 2500 mL
m = 2500 * 23.22 / 100
m = 58050 / 100
m = 580,5 g
Is this an addition problem?
B. criteria because it's a principal or standard by which something may be judged or decided <span />
Answer:
Power plants.
Explanation:
When power plants start the burning coal process, the chemical bonds carrying its carbon atoms are brake down and releasing energy also carrying heavy metals such as lead, mercury, and cadmium into the atmosphere.
When the sulfur which is present in coal reacts with oxygen it produces sulfur dioxide and they the ability to combines with other lethal toxic molecules that are found in the atmosphere and form small, acidic particulates that can cause several diseases in humans.
Answer:
D) There are 33 particles inside of the nucleus and 16 particles outside of the nucleus.
Explanation:
Sulfur has an atomic number of 16. The atomic number represents the number of protons, so sulfur has 16 protons.
This atom of sulfur has a mass number of 33. The mass number is the sum of protons and neutrons. Then, the number of neutrons is 33 - 16 = 17
Sulfur is a neutral atom. Therefore, it has the same number of positive charges (protons) and negative charges (electrons). Thus, sulfur has 16 electrons.
Protons and neutrons are in the nucleus and electrons are outside the nucleus.
Taking all the above into account, the correct answer is:
D) There are 33 particles inside of the nucleus and 16 particles outside of the nucleus.
