Wood is a suspension.
The easiest way I believe to find out whether a substance is a colloid or a suspension is determining is determining if the particles in a substance separate when sitting still. Unlike those in a suspension, particles in a colloid do not separate when sitting still.
Hope this helped!
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 answer is c, relying on renewable energy sources
The best word to fill the blank is "saturated". Hydrocarbons with only single bonds are saturated. These hydrocarbons are the deemed to be the simplest class. They are called saturated because each carbon is bonded to as many hydrogen as possible.
