Which element found in both biotite mica and muscovite mica, makes up the greatest percent by volume of earths crust.
Answers
Answer 1
Answer:
Answer;
Oxygen
Explanation;
Oxygen is the element that is found in both biotite mica and muscovite mica and makes up the greatest percent by volume of earths crust.
The most common chemical elements that are found in the earth's crust includes; Oxygen-46.6%, silicon-27.7%, aluminium- 8.1%, Iron - 5.0%, calcium- 3.6%, etc. This is evident that oxygen is the greatest chemical element in the earth's crust.
The chemical element oxygen is also found in minerals biotite mica and muscovite mica. The major difference is that Biotite contains elements iron and magnesium while muscovite does not.
Which statement about stomata is true?A.)The number of stomata is greater on the upper surface of the leaf.
B.)The number of stomata is greater on the lower surface of the leaf.
C.)The number of stomata is equal on both surfaces of the leaf.
Answers
The answer is B. The number of stomata is more on the lower surface of the leaf. The primary function of the stomata is to regulate moisture loss from the plant. The upper surface of the leaf is more exposed to the air and sunshine thus water is more susceptible to evaporation. However, the stomata is abundant on the lower surface, the location of it helps the plants to conserve more water

8. which statement best explains why compounds have different properties than the elements that form them?
Answers
Since options aren't given the responder will display the answer.
They are bonded by atoms.
The atoms in a compound are held together by a chemical bond. The chemical bonds can be either covalent bonds or ionic bonds. Both the bonds are considered very strong bonds. These bonds are mainly formed by sharing of electrons or in the case when one of the elements making the compound donates electron to the other element. The nucleus of each atom attracts to form a strong bond. This property of attraction between the nucleus of the atoms actually helps in forming the chemical bonds.

If element X has 15 protons, how many electrons does it have?
Answers
If element X has 15 protons, it would also have 15 electrons.
If the element has 55 protons it is celcium and it also has 55 electrons. It has an atomic mass of 133 (132.9) so to get the number of neutrons you subtract the atomic mass and the number of protons.
