Answer:
86.2% of Hg in the ore
Explanation:
Percent composition is defined as one hundred times the ratio between mass of an element in a compound and total mass of the compound. Formula is:
% composition = 
If an ore weights 681g and contains 587g of mercury, percent composition is:
(587g Hg / 681g) × 100 = <em>86.2% of Hg in the ore</em>
Answer:
SN2
Explanation:
The first step of ether cleavage is the protonation of the ether since ROH is a better leaving group than RO-.
The second step of the reaction may proceed by either SN1 or SN2 mechanism depending on the structure of the ether. Methyl and primary ethers react with HI by SN2 mechanism while tertiary ethers react with HI by SN1 mechanism. Secondary ethers react with HI by a mixture of both mechanisms.
Dipentyl ether is a primary ether hence when treated with HI, the reaction with HI proceeds by SN2 mechanism as explained above.
Answer:
during reaction magnesium lises ions.
Explanation:
magnesium reacts by losing two ions which makes it smaller in size.
Answer:
The answer is 1. A type of acid that completely reacts with water.
Explanation:
A strong acid dissociates completely in water to release hydrogen ions as the only positive ions.
This is the simple definition of Arrhenius acid.
