Explanation:
probably because, X rays are used to ionise the gas molecules, which is loss of electrons, these electrons are absorbed by oil drops
The answer is a. H+ and H2O. For a half-reaction in acidic solutions, elements that are not hydrogen and oxygen are balanced first. Then we add H2O to balance oxygen atoms and we add H+ to balance the hydrogen atoms. We do the same steps for basic solutions, but we also add hydroxide ions OH- in the latter part.
I believe the correct answer to this question is:
“Mixtures”
By definition, mixtures are combination of substances
which are not really chemically combined and hence separable by physical means.
There are two types of mixtures, homogeneous and heterogeneous, both are also
separable by physical means.
<span>This is as opposed to Compounds which are chemically
bonded and cannot be separated by physical means.</span>
It’s 34 I had this question
Answer : Average atomic weight of copper atoms will be
63.62 u.
Explanation : For calculating average atomic weight for any given atom we use this formula,
m = Σ

X % abundance
where, m - avg atomic mass of isotope.
and

- mass of isotope
on solving we get,
m = [63 u X (69/100)] + [65 u X (31/100)] = 63.62 u.
