Number of atoms or ions of each element that are combined in the compund
Answer:
A pure substance consists only of one element or one compound and a mixture consists of two or more different substances, not chemically joined together.
So, a mixture is like mixing - let's say - sugar and rice together (dry BTW), but you can clearly see both substance are not chemically mixed together, if that makes sense. Thus, you can easily separate them out.
Answer:
Work done, W = 128 kJ
Explanation:
Given that,
Weight of a mountain climber, F = 800 N
It climbs to a cliff that is 160 m high.
We need to find the work done by the mountain climber. The work done by an object is given by the formula as follows :
W = Fd
Put the values of F and d.
W = 800 N × 160 m
W = 128000 J
or
W = 128 kJ
So, 128 kJ of work is done by the mountain climber.
Stratospheric ozone is formed naturally through the interaction of UV radiation with molecular oxygen.
