The complete ionization of KBr into its constituents
is:<span>
<span>KBr (s) --->
K+ (aq) + Br- (aq)</span></span>
<span>
During electrolysis, oxidation takes place at the anode electrode. This means
that an ion is stripped off its electron hence becoming more positive:
<span>2 Br- (aq) --->
Br2 (g) + 2e- </span></span>
We can see that Bromine gas Br2 is evolved at the anode.
<span>
<span>Meanwhile at the cathode, the reduction reaction occurs.
Which means that the electron from the anode electrode is used to make an ion
more negative:
<span>2K+ (aq) + 2e- ---> 2K (s) </span></span>
Hence, through reduction, solid potassium is deposited on the
plate.</span>
Half reactions:
<span>Anode: 2 Br- (aq) --->
Br2 (g) + 2e- </span>
<span>Cathode: 2K+ (aq) + 2e-
---> 2K (s) </span>
Hi!
I believe that there were the following options in this question:
<span>A) Which color bends the most to make a rainbow?
B) What color of scented marker has the best smell?
C) Which flower has the prettiest shade of purple on its petals?
D) What is the best-looking color on a high-performance sports car</span>
Now, options b), c) and d) are about a personal preference and opinion - they are not scientific uqestions.
The correct answer is a) - it asks about the properties of light.
A Many people who came to the hospital had very serious injuries.
Explanation:
From the passage, we can infer that many people who came to the hospital had very serious injuries.
Let us analyze the given options:
Many doctors were worried about the safety of their own families.
No where in the passage was the families of the Doctors mentioned. The passage directly spoke to the Doctors and their victims.
Many people were able to quickly leave the hospital after treatment.
There was shortage of blood and there was no way they could have been treated without it. The passage suggests an emergency situation was up.
Also, many people needed blood for treatment but there was an acute shortage. No way to treat and discharge them.
Many doctors who worked through the night wanted to go home.
Again, no text in the passage suggests this. We have a picture of Doctors who wanted to tend to their patients but lacked the means to do so.
<em>The fitting inference that can be drawn from the passage is that many people came to the hospital had serious injuries which led to blood shortage. </em>
