With the different media right now that can be the sources of different information, it is hard to confirm whether what we have is true, legit, or not. One way to confirm is to source out the information to many different sources. The advisable number of sources should be at least three.
The rate of Formation of Carbocation mainly depends on two factors'
1) Stability of Carbocation: The ease of formation of Carbocation mainly depends upon the ionization of substrate. If the forming carbocation id tertiary then it is more stable and hence readily formed as compared to secondary and primary.
2) Ease of detaching of Leaving Group: The more readily and easily the leaving group leaves the more readily the carbocation is formed and vice versa. In given scenario the carbocation formed is tertiary in all three cases, the difference comes in the leaving group. So, among these three substrates the one containing Iodo group will easily dissociate to form tertiary carbocation because due to its large size Iodine easily leaves the substrate, secondly Chlorine is a good leaving group compared to Fluoride. Hence the order of rate of formation of carbocation is,
R-I > R-Cl > R-F
B > C > A
Answer:
Option 3 = i.e. If you add the masses of all the products after fission, they are LESS than the mass of the reactants
Explanation:
Nuclear fission: Is the process in which the nucleus of radioactive element with higher mass undergoes fission and get into fragment of smaller mass with release of high energy.
The products of the nuclear fission are the fragment of smaller nuclei.
For example, larger nucleus that of uranium split into two small nuclei along with some neutrons, energy and gamma rays.
The mass of the original atom always more than the sum of the atomic masses of the atoms produce by fission. The reason is neutrons and kinetic energy lost, and upon cooling we get product masses less than original.
Answer: That would be false because it is the contact between two layers representing a gap in the geologic record, usually from the erosion of the layers which would normally be expected to appear.
Explanation:
Have a good day
I hope this helps if not sorry :(

The radiation emitted is a beta particle with a -1 charge. Beta particles have a <span>medium penetrating power. An emission of beta particles requires shielding because of the hazards it pose to humans. Thus, one characteristic of this radiation is that <span>some shielding is required.</span></span>
