Hi,
"Phosphorous is normally found as a solid, but since it reacts with oxygen it is not normally found in an elemental form"
Have a great day!
Answer:
The emission spectrum of a chemical element or chemical compound is the spectrum of frequencies of electromagnetic radiation emitted due to an atom or molecule making a transition from a high energy state to a lower energy state.
Answer:
In CO, the oxidation number of C is (+2), and that of O is (-2).
In H_2H2 , the oxidation number of H is (0).
In CH_3OHCH3OH , the oxidation number of C is (-2), that of O is (-2) and that of H is (+1).
Explanation :
Oxidation number : It is also called oxidation state. It is a number assigned to an element in a chemical compound that represent the number of electrons gained or lost by an element in a compound.
So, water reacts with hydrochloric acid in the following formula
H2O + HCl —-> H3O+ + Cl-
We can visualize that when the two react, the hydrogen ions is taken on by the water molecule. This satisfies one of the definitions for a base
Bronsted acids = anything that donates a proton (H+ ion)
Bronsted bases = anything that accepts a proton (H+ ion)
So, as we can see, that is exactly what is happening. The Cl- and H+ detach and then the water takes on that extra H+.
H3O+ is what we call a hydronium ion
