you discover that an atom of an unknown element had 54 protons. identify the element and explain how you know the identity is correct. explain whether the unknown element is more or less reactive than an atom of an element that has 30 protons. identify an element that would have very similar chemical properties (as element 54) to the unknown element and explain why its chemical properties would be similar.

Answers

Answer 1

Answer: Xenon

Explanation:

if you look on the periodic table of elements, youll notice that the only element with 54 protons is Xenon. Hope this helps!!

Answer 2

Protons are the positive charged subatomic particle that lies with the neutron in the nucleus of the atom.

The unknown element with 54 protons will be Xenon.

It is because Xenon is the only element in the periodic table having 54 protons. Element has the same number of protons and electrons therefore Xenon is the element that will have 54 protons.

It belongs to the noble gas group because the outer shell is a filled valence shell that is stable and less reactive compared to other elements.

Therefore it will be less reactive compared to the element having 30 protons.

The elements having similar properties as Xenon will be helium, neon, argon etc because they have the same group in the periodic table.

Summarize photosynthesis and describe how it is part of the carbon cycle

Answers

Photosynthesis is when plants take in carbon dioxide and create glucose and oxygen. It is apart of the carbon cycle because it removes carbon from the air and turns it into oxygen.
Photosynthesis is the action of plants taking in sunlight to make their food. Just like us humanos make our own food they do the same thing when they get sunlight. This is part of the carbon cycle because during photosynthesis plants absorb sunlight and Carbon dioxide and in the end and let out oxygen.

10. before replication begins, the strands of DNA are separated and used as templates for the new strands. the replication process creates 2 identical double helixes, each has 1 new strand and 1 old one.

11. without dna replication, damaged cells could not be replaced/repaired and cells need dna, cells would become mutated without dna replication.

12. mutations are rare because dna polymerase proofreads the strands but if the process occurred incorrectly and was not corrected by the polymerase, the cell would become mutated and could be really harmful.

11.) each of the newly replicated helics is formed from a semi-conservative parent strand and one daughter strand

12.) because it creates the next copy of DNA that have to into one of the two daughter cells when a cell divides. Without it each cell lacks enough hereditary fabric to give instructions for crating proteins vital for bodily purposes.
