Answer:
The elements in this list are:
Silver, hydrogen, carbon, nitrogen, gold, magnesium, nickel, mercury.
Explanation:
Elements are chemical substances that can be found on the periodic table.
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
)
=
1.479108388
×
10
−
13
We can round (if required) to
1.479
×
10
−
13
.
Thus, there are
1.479
×
10
−
13
concentration of hydrogen ions

.
Hope this helps :)
Answer: Isotopes of an atom are different because they have different atomic masses and different number of neutrons within their nucleus. They are the same since they will always have the same atomic number/number of protons in their nucleus.
Explanation:
It's absolutely TRUE...........
