Answer:
CH3Br ( Methyl Bromide )
Explanation:
H9 C3 Br3 => rewrite as: C3H9Br3 => actually, this is 3 moles of molecule CH3Br !
C3H9Br3 ~ 3( CH3Br)
I hope this answer can help you. Have a nice day!
Answer:
B. The region outside a nucleus where the electron is moving
Explanation:
The more the electron moves, the higher energy level it has, the slower the electron moves the lowwer energy level it has.
The 2 types of mechanical weathering are .....
1) * Temperature Change
-Temperature change makes rocks contract and expand
-Also one of the important cause of mechanical weathering.
2) * Abrasion
-Abrasion is a process in which an external force
Example: water movement or gravity which causes rock materials grind (reduce <<< synonyms) which can break apart the outer layers of affected rocks.*PLEASE GIVE THIS A THANKS :) :D xD AND ALSO THE BRAINIST ANSWER PREETTY PLEASEEEEEEEE, DON'T YOU EVER FEEL LIKE YOUR GOOOOING TO GIVE ME THE BRAINIEST ANSWER/CROWN??? xD
Answer:
Explanation:
A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.
A double displacement reaction in which on e of the product is formed as a solid is called as precipitation reaction.
The balanced chemical equation is:
Answer:
The Equilibrium will shift to the left.
Explanation:
The reaction at equilibrium is as follow,
CH₃COOH ↔ CH3COO⁻ + H⁺
According to Le Chatelier's Principle," When a system (reaction) at equilibrium is subjected to any stress (like change in Concentration, Pressure, Temperature e.t.c) the system (reaction) tends to adjust itself in such a way so as to minimize the effect of that change".
Hence, in above reaction when Sodium Acetate (source of CH₃COO⁻) is added the equilibrium will shift in left side and will decrease the concentration of CH₃COO⁻ions.
