The answer would be C as in cat and D as in dog your welcome i hope this help
Explanation:
dredge to do with me to do with me to do with me to do with me to do with me to
Explanation:
acid --> HCN
base --> KCN
now
another base NaOH is added
we know that
base will react with an acid
so
OH- + HCN ---> CN- + H20
we can see that
HCN is used up , so number of moles of HCN will decrease
CN- is being formed , so number of moles of CN- will increase.
A false
B false
C false
D true
E false
Answer:
Explanation:
Your B-L Acid is a proton (Hydrogen, H+) donor, and your B-L base is a proton acceptor. This means that the base will take a hydrogen from your acid. NO2- is a B-L base, and you can tell it is a base by the negative charge it possesses. This means that it has a lone pair that wants to grab one of the hydrogens from NH4+, the B-L acid. In scientific words, the NO2- is a nucleophile and NH4+ is an electrophile. The result of NO2- grabbing that hydrogen from NH4+ is that NO2- becomes HNO2 (your conjugate acid) and and NH4+ becomes NH3 (you conjugate base). Basically, any time a B-L acid loses a proton, its equal product will be its conjugate base, and any time a B-L base gains a proton, its equal product will be its conjugate acid.
I hope this helped explain the concept behind Bronsted-Lowry acids and bases! Good luck with your class and please don't forget to give a positive rating! :-)
