xplanation:
A line shows a bonding pair of electrons (which are usually 2 for every line) – the atoms involved in the bond share two electrons per bond to form a covalent bond. The two dots show a pair of lone electrons NOT involved in bonding.
The Carbon and Sulfur will require to have their valence orbital shell involved in the bonding to have 8 electrons. The Hydrogens need 2 to achieve stable electron configuration. This way the atoms achieve stability in the molecule
Answer:
The correct option is C (Uncompetitive inhibitor)
Explanation:
- Uncompetitive inhibitor takes place when an inhibitor binds at different site (allosteric site) of the enzyme after the substrate forms a complex with the enzyme.
- The Uncompetitive inhibitors bind to a different site on the enzyme while the substrate binds to the active site on the enzyme.
- It differs from non-competitive inhibition because non-competitive inhibition can occur with or without the presence of the substrate.
- Uncompetitive inhibition is also referred to as Anti-competitive inhibition.
Answer:
Tom is correct. The rate of reaction of Crystal violet and NaOH is first order with respect to NaOH, hence, a higher concentration of NaOH corresponds to a higher rate of reaction; a faster reaction.
This means the speed of cleaning depends on the concentration of the lye used.
Explanation:
The reaction between Crystal violet and NaOH, represented as
CV⁺ + OH⁻ → CVOH
It is a reaction that is know to turn the violet colour of the crystal violet colourless.
The rate of the reaction is also known to be second order; first order with respect to Crystal violet and first order with respect to NaOH.
This means that the rate of reaction is directly proportional to the concentration of NaOH provided all other parameters such as the rate constant and the concentration of Crystal violet are constant.
Hence, the reaction becomes faster with an increased concentration of NaOH.
So, Tom is right, concentrated lye solution would remove the stain faster.
Bob is wrong.
Hope this Helps!!!
B.
I hope this will help a bit (Forgive me of its wrong pls)
