An example is when light goes from traveling on air to the water. A famous experiment that is done on many schools to prove this is the one with the pencil on a cup of water. I added both pictures so you are able to visualise what I'm trying to say. The pencil "bends" on the water because of a phenomenon called refraction. <span>When light enters water, it cannot move as fast as it </span>does in air, therefore, a<span>s the light enters the water, it </span>bends<span> away from its original path. Hope I was able to help!!</span>
Answer:
E cell = +1.95 V
Explanation:
At Anode : Oxidation reaction takes place
At Cathode : Reduction reaction takes place
The reaction with lower value of reduction potential will undergo Oxidation
E = -1.18 V
This equation undergo oxidation reaction and become:
Anode(Oxidation-Half) :
E = +1.18 V
Cathode(Reduction-Half) :
E =+0.77 V
To balance the reaction multiply reduction-Half with 2.We get :
Note that E is intensive property , do not multiply E of oxidation-half with 2
Ecell = 0.77 -(-1.18)
E = +1.95 V
Answer:
The answer is option C; the reaction is at equilibrum
Electrons are strongly attracted to the protons in the nucleus of an atom.
The more protons in a nucleus, the more strongly an electron is attracted.
Hope this helped! :D
