I think it's RbCl and CaO
Answer:
When a atom is unstable (It wants to gain or lose a valence electron)
Answer is: t<span>he partial pressure of the hydrogen 500 mmHg.
p(total) = 523.8 mmHg.
p(water) = 23.8 mmHg.
p(total) = m(water) + p(hydrogen).
p(hydrogen) = p(total) - p(water)..
p(hydrogen) = 523.8 mmHg - 23.8 mmHg.
p(hydrogen) = 500 mmHg.
mmHg or</span><span> </span>millimeter of mercury<span> is a </span>manometric unit<span> of </span><span>pressure.</span>
The answer is (2) chlorine. We can figure out some rules of properties of elements from the periodic table of elements. One of the important rule is that the elements which belongs to the same group has the similar properties. Fluorine and chlorine belong to the same group.
