It depends if the zinc ion lost or gained an electron. But electrons are more than 2,000 times smaller than a proton or neutron so small diffrence.
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
m
o
l
L
.
Hope this helps :)
According to Heisenberg's Uncertainty Principle,
ΔE×Δt ≥ h/(4π)
where h = planck's constant = 6.63 ×
J.s
Hence, ΔE ≥
=
∴,
ΔE ≥ 8.5086 X
J
If all the reactors are used, the pressure inside the flask will most likely increase to 4 atm.
<h3>What is atmospheric pressure?</h3>
Atmospheric pressure is a force per unit area exerted by the air in the atmosphere on the Earth's surface. The value of atmospheric pressure above sea level is 1013.25 hPa.
<h3>What influences the variation of atmospheric pressure?</h3>
The atmospheric pressure varies from different meteorological factors such as:
- Decreases with altitude.
- It varies according to latitude, the lowest atmospheric pressure at sea level is reached in the equatorial latitudes.
- The equatorial zone has high atmospheric pressures for dynamic reasons derived from the Earth's rotation.
According to the above, if all the reactors are used at atmospheric pressure, it will most likely increase.
Note: This question is incomplete because some information is missing. However I can answer it based on my prior knowledge.
