Answer:
45 neutrons
Explanation:
Bromine has 35 protons and a mass number of 80. a) How many neutrons does the atom of bromine have? The mass number = protons + neutrons. Bromine has a mass number of 80 and 35 protons so 80-35 = 45 neutrons.
33 - 15 = 18
This element is P-33
Answer:
1947 the United States Army had an excess of metallic sodium left over from World War II and determined that the alkaline waters of Lake Lenore would be a good spot to dump and neutralize the acidic element, which reacts with water with intense explosions.
Explanation:
there ya go
They share four electrons, two from each oxygen atom
Answer: a) The
of acetic acid at
is 
b) The percent dissociation for the solution is 
Explanation:

cM 0 0

So dissociation constant will be:

Give c= 0.10 M and
= ?
Also ![pH=-log[H^+]](https://tex.z-dn.net/?f=pH%3D-log%5BH%5E%2B%5D)
![[H^+]=1.35\times 10^{-3}M](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D1.35%5Ctimes%2010%5E%7B-3%7DM)
![[CH_3COO^-]=1.35\times 10^{-3}M](https://tex.z-dn.net/?f=%5BCH_3COO%5E-%5D%3D1.35%5Ctimes%2010%5E%7B-3%7DM)
![[CH_3COOH]=(0.10M-1.35\times 10^{-3}=0.09806M](https://tex.z-dn.net/?f=%5BCH_3COOH%5D%3D%280.10M-1.35%5Ctimes%2010%5E%7B-3%7D%3D0.09806M)
Putting in the values we get:


b)
