The difference between Cracking and Pyrolysis in the former is the process of whereby complex organic molecules such as kerogen or long chain hydrocarbon are broken into a simpler molecule while the later is a thermochemical decomposition of organic material at elevated temperature in the absence of oxygen.
Answer:
This happens when there are too many protons in the nucleus, because the positive protons repel each other. When two protons fuse together, one of them decays into a neutron. Our new nucleus now has one proton and one neutron. PLEASE MARK AS BREINLEST.
The electron configuration 1s22s22p6323p2
is the element Silicon.
No; it can only ever be at half pressure

Acid is anything which will give H+ to other species.
Have a look at the equations given.
In A) HCl changes to Cl- by giving its H+ to H2O. So HCl is an acid.
In B) HCO3- changes to H2CO3^2- by accepting H+. It did Not give its H+ rather it takes from other species. So it is not an acid at all.
In C) H2O is just breaking to H+ and OH-. It is not giving H+ to other species. So it is also not an acid in this reaction.
In D) HCOOH is giving its H+ to H2O. So it is also an acid.
So out of all reactions with water. The only two species are acting as acid with water namely HCl and HCOOH.
Out of these two HCl is very strong acid but HCOOH is a weak acid.
So the answer is D
