Answer:
Concentrated sulfuric acid is used as a catalyst, and has a dual role:
-Speeds up the reaction.
-Acts as a dehydrating agent, forcing the equilibrium to the right and resulting in a greater yield of ester.
In 1 mole of magnesium there are Avogadro's number of atoms are present.
Avogadro's number = 6.023 x 10²³
1 mole = 6.023 x 10²³ atoms
3.75 moles = 3.75 x 6.023 x 10²³
=2.26 x 10²⁴
So, in 3.75 moles of magnesium there are 2.26 x 10²⁴ atoms of magnesium are present.
I have no idea!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
False
Explanation:
It's classified as a dwarf planet, but not technically a planet.
I think the answer would be : Tetrahedral
Oxygen has 6 electrons and need 2 more electron to complete its octet. In Tetrahedral, the electrons are arranged so it surround the oxygen and forming a 109 degree bond angel/
hope this helps
