I think one is Hydrochloric acid
0.00032 / 140000000
=0.000000000002
=2 x 10^-12
The answer is 1. This is because electronegativity increases up a group and across a period. So metals are going to be the least electronegative. 4.0 is the most electronegative element on Paulina's Scale!
Answer:
Explanation: Sediments or sedimentary rocks are formed from pre-existing rocks broken through the agents of denudation such as air, ice, water flow which carries the particles and deposits it, the accumulation of one layer on the others is called DEPOSITION. As the deposits keeps building, LITHIFICATION occurs which involves overburden pressure acting on the sediments in layers.
Note that during deposition oldest layers are below, while the younger layers are above
