Answer:
if you check there penetrating power it is not equal so you have to consider that when talking about there electrophilic rxn in of furan.
Explanation:
they both travel at the speed of light 3.0 *10^8m/s, and their varying wavelengths
Answer:
Option A:
Zn(s) + Cu^(2+) (aq) → Cu(s) + Zn^(2+)(aq)
Explanation:
The half reactions given are:
Zn(s) → Zn^(2+)(aq) + 2e^(-)
Cu^(2+) (aq) + 2e^(-) → Cu(s)
From the given half reactions, we can see that in the first one, Zn undergoes oxidation to produce Zn^(2+).
While in the second half reaction, Cu^(2+) is reduced to Cu.
Thus, for the overall reaction, we will add both half reactions to get;
Zn(s) + Cu^(2+) (aq) + 2e^(-) → Cu(s) + Zn^(2+)(aq) + 2e^(-)
2e^(-) will cancel out to give us;
Zn(s) + Cu^(2+) (aq) → Cu(s) + Zn^(2+)(aq)
Answer:
#1 You get valid data for one.
#2 Not measuring accurately can have some bad consequences.
#3 If you mix the wrong amount of chemicals you can end up getting yourself or worse other people hurt.
#4 When making food you need to measure the amount of sugar or salt you put into the dish or else your face will be this
