An element's mass is determined by <span> adding up the </span>masses <span>of protons and neutrons.</span>
Answer:
s<p<q<r
Explanation:
Given
Element s displaces p from its oxide. Thus, s is more reactive that p
p reacts with cold water but element q cannot react with cold water. Thus,
p is more reactive than q
Element q is able to react with weak or dilute acids but element r in unable to react with weak or dilute acids. Thus, q is more reactive that r
The order of four elements on the basis of their reactivity in descending order is as follows
s<p<q<r
The pascal (pronounced pass-KAL and abbreviated Pa) is the unit of pressure or stress in the International System of Units (SI). It is named after the scientist Blaise Pascal. One pascal is equivalent to one newton (1 N) of force applied over an area of one meter squared (1 m2).
