Answer:
The value of Ka
It is a weak acid
Explanation:
From the question we are told that
The concentration of
The concentration of
The concentration of
Generally the equation for the ionic dissociation of is
The equilibrium constant is mathematically represented as
Substituting values since all value of concentration are at equilibrium
Since the value of is less than 1 it show that in water it dose not completely
disassociated so it an acid that is weak
I think th correct answer is D. Change the shape in therefore surface area. Hope this helps :)
Answer:
i know that 10 x is .22300
Answer:
C₆H₆
Explanation:
Molar mass of the compound is 78g/mol
Unknown:
Molecular formula of the compound = ?
Solution:
The empirical formula of the compound is CH.
Empirical formula is the simplest formula of a compound.
To solve this problem:
Find the molar mass of CH;
Molar mass = 12 + 1 = 13g/mol
Multiplication index = = 6
So;
(CH)₆ ;
Therefore:
C₆H₆
