Answer:
Jamal hiked = 44/3 miles
Step-by-step explanation:
Mixed numbers are given in this question which can be changed into fractions by multiplying the denominator by quotient and adding numerator to it.
Given that:
Length of first trail: 5 1/3 = (3*5 + 1)/3 = 16/3 miles
According to given condition:
Length of second trail: 1 3/4 * 16/3 = (4*1+3)/4 * 16/3 = 7/4*16/3
By simplifying:
Length of second trail = 28/3 miles
So the total miles Jamal hiked = 16/3 + 28/3
Jamal hiked = 44/3 miles

The buffer will probably be destroyed by the addition of HCN.
<h3>What is buffer solution?</h3>
A weak acid and the conjugate base of the weak acid, or a weak base and the conjugate acid of the weak base, are combined to form the buffer solution, a water-based solvent solution. They withstand being diluted or having modest amounts of acid or alkali added to them without changing their pH.
Given that a 1.0 l buffer solution is 0.15 m in HCN and 0.10 m in NaCN.
We need to find a action which one destroy the buffer solution.
A buffer is a substance made of salt and a weak acid that is beneficial. From the aforementioned chemicals, HCN is a potent acid and NaCN is a salt between HF and NaCN. Therefore, the buffer will probably be destroyed by the addition of HCN.
