Answer:
A reaction at equilibrium implies that the concentration/amount of reactants & products present in that reaction don't change but will remain constant. It could also mean that the forward reactions and reverse reactions will occur at the same rates.

No it is a organic molecule.
Answer:
There are
1.479
×
10
−
13
concentration of hydrogen ions
m
o
l
L
.
Explanation:
Because pH is a logarthmic scale, we can use the formula:
[
H
+
]
=
10
-pH
. Where...
=>
[
H
+
]
is the concentration of hydrogen ions in the solution.
=>
p
H
is the pH of the solution.
=> Where
10
is the base of the power - it's a logarithm formula.
We can now just sub in the values and solve for [
H
+
]
.
[
H
+
]
=
10
-pH
=
10
−
(
12.83

−
13
We can round (if required) to
1.479
×
10
−
13
.
Thus, there are
1.479

−
13

Hope this helps :)
Answer:
the answer is 2,000 nickels.
Explanation:
we multiplied 100 by 100, because there are 100 cents in a dollar, and we divided 10,000 by 5, because there are 5 cents in a nickel.
