To draw the Lewis structure of the polyatomic ion, 
you would have to add one electron to those in the structures of Cl, O, O and O.
Answer: Option A
<u>Explanation:</u>
It is a kind of representation of electrons present in valence shell of each element. For easy understanding of how the outermost electrons will be arranged for bonding purpose, Lewis structure is used.
As we know that carbon has an outermost electron number of 4. So 4 electrons are required as the electrons in the outermost shell of each carbon. But here only three electrons are there, so one electron need to be added in the Lewis structure of .
Answer:
A
Explanation:
A catalyst refers to an enzyme composed of peptides in their tertiary conformation.
The addition of a catalyst provides a new path to the reaction and the reaction proceeds in a faster way compared to the reaction without a catalyst.
The peptides are arranged in such a way that they form a pore-like structure which allows the binding of the substrate molecules by forming a temporary covalent bond. These bonds lower the activation energy of the complete reaction which is required to initiate a reaction.
In the given diagram, the activation reaction is represented by the letter "A" and therefore a catalyst will lower and alter the value of A.
Thus, Option-A is correct.
Answer:
It refers to the conventional sense of the elastic current
Explanation:
It is the traditional or the conventional sense of the elastic current as in the earlier days the experimenters and the scientist thought that the current moves out of the positive terminal or pole of the battery and enters through the negative pole or terminal of the battery.
It is because of the direction of the current flow as thought in early days, the sentence refers to the conventional sense.
Hello there! I'm gladly to help you out! :)
Melting Ice melts when heat energy causes the molecules to move faster, breaking the hydrogen bonds between molecules to form liquid water.
Hope this helped!
