Bond dissociation energy is inversely proportional to Bond length.
The longer the bond is, lesser the energy it requires to break the bond.
Therefore, it is easier to break single bond.
Single bond>double bond>triple bond -------(Bond length)
D. is the missing element.
Carlos <em>hasn’t done research</em> on what other scientists have observed and investigated on this topic. If he hasn’t done his literature research, he may just be repeating the experiments of other scientists working in the same area.
Options “A.”, “B.”, and “C.” are all part of the scientific method.
Answer:
Energy cannot be created nor destroyed
Explanation:
Law of conservation of energy
A buffer has roughly equal concentrations of a weak acid and its conjugate base. The only acids in the question are HNO3 and HNO2. HNO3 is a strong acid, so it can’t be used for a buffer. The first option has HNO2 and hydrochloric acid, which won’t supply the conjugate base of HNO2, which is NO2^-1. NaCl isn’t an acid or a base, so we can eliminate that as well. That leaves us with HNO2 and NaNO2. Group 1 metals are spectators in acid-base equilibria, so we can ignore Na once it disassociates. That will give us .1M HNO2 and .1M NO2^-1, which is what we want.
<span>A greater amount of HCl will be needed to conclude the titration as the concentration of the borax solution is half of what it is needed to be. Thus, double the amount of HCl will be needed to conclude the titration</span>
