Answer:
A). half, higher
Explanation:
The Formal charge is elaborated as the 'allocated charge to a molecules' atom' on the basis of the assumption that the electrons present in the chemical bond are equally split among the atoms. It is estimated by 'halving the no. of bonding electrons that encircle the atom.
While Oxidation number is characterized as the 'hypothetical charge of an atom that is present within a molecule.' It is also defined as 'the actual number of lost or gained electrons or the rate at which the electrons are gained or lost by an atom to develop a chemical bond along with the other atom.' It is <u>calculated by allocating or sharing the electrons having the higher electronegativity belonging to a specific bond with the other</u>. Thus, <u>option A</u> is the correct answer.
Answer:The dissociation constant of a weak acid is 4.9 ~ 10-8 , its percentage ionization at 0.1 M is ( a ) ... The pH of a 0.1 M aqueous solution of a weak acid ( HA ) is 3.
Explanation:acid. Ka acetic acid = 1.8χ10–5. (b) A buffer solution is prepared by adding 0.10 liter of 2.0 ... Compute the hydrogen ion concentration of the buffer solution.
Answer:
A
Explanation:
An unbalanced force is your answer.
<h3><u>Answer;</u></h3>
C. The equilibrium position will shift away from what was added to lower its concentration.
<h3><u>Explanation;</u></h3>
- Le Chatelier's principle states that; if a system at equilibrium is disturbed, the equilibrium position will shift to counter the effects of the disturbance.
- At equilibrium, the system is disturbed when a change in conditions forces it temporarily out of equilibrium. There are three common disturbances:
1. Change in concentration.
2. Change in pressure (caused by a change in volume).
3. Change in temperature.
