Answer:
24 hours
Explanation:
The computation is shown below:
The needed mole of
is
= 5 ÷22.4 = n
Also 1 mole of
required four electric charge
Now the charge needed is
= n × 4 × 96,500 C
= 4 × 96,500 × 5 c ÷ 22.4
= 86160.714 C
Now
q = i t
t = q ÷ i
= 86160.714 C ÷ 0.995
= 86593.7 seconds
= 24 hours
Hence, the correct option is A.
Answer:
A reaction that combines simpler reactants to form a new compound is called a
<h2>Synthesis reaction.</h2>
The two angles would be both 41 degrees.

x in this case would be 14 degrees.
Answer:
r = 3.61x
M/s
Explanation:
The rate of disappearance (r) is given by the multiplication of the concentrations of the reagents, each one raised of the coefficient of the reaction.
r = k.![[S2O2^{-8} ]^{x} x [I^{-} ]^{y}](https://tex.z-dn.net/?f=%5BS2O2%5E%7B-8%7D%20%5D%5E%7Bx%7D%20x%20%5BI%5E%7B-%7D%20%5D%5E%7By%7D)
K is the constant of the reaction, and doesn't depends on the concentrations. First, let's find the coefficients x and y. Let's use the first and the second experiments, and lets divide 1º by 2º :



x = 1
Now, to find the coefficient y let's do the same for the experiments 1 and 3:




y = 1
Now, we need to calculate the constant k in whatever experiment. Using the first :


k = 4.01x10^{-3} M^{-1}s^{-1}[/tex]
Using the data given,
r = 
r = 3.61x
M/s
Fluorine(F)
Explanation:-
- Fluorine has Z=9
- +2 charge means 2 electrons donated (7left only)
Lets look at Electronic configuration
