Ammonia is a gas for which reliable analytical methods are available to determine its concentration in other gases. To measure flow in a natural-gas pipeline, pure ammonia gas is injected into the pipeline at a constant rate of 72.3 kg/min for 12 min. Five miles downstream from the injection point, the steady-state ammonia concentration is found to be 0.382 wt %. The gas upstream from the point of ammonia injection contains no measurable ammonia. How many kilograms of natural gas are flowing through the pipeline per hour?
amount of ammonia injected:
72.3 kg/min x 12 min = 867.6 kg
ammonia concentration = 0.382%
[tex]\tt 0.382\%=\dfrac{mass~amonia}{mass~ammonia+mass~natural~gas}\times 100\%\\\\0.00382=\dfrac{867.6}{867.6+mass~natural~gas}\\\\mass~natural~gas=226,252.88~kg/12min=1131264.4~kg/h[/tex]

Which characteristic of an outermost shell is required for an atom to not need any electrons?
1 electron
more than 2 electrons
more than 21 electrons
a full
Answer:
A full.
Explanation:
An electron needs to have a full octet do not need any more electrons. So the correct option is D.
What is a valence shell?
The s and p electrons in the outermost shell are valence electrons. Core electrons are those found in the inner shell. Valence electrons are little subatomic particles that we come across as we examine and investigate an element's atom. We can trace the valence electrons and forecast the sorts of bonds with the aid of Lewis structures.
The majority of valence electrons are negatively charged particles, and they are all grouped in various orbitals or shells. Additionally, these electrons are in charge of how atoms interact with one another and create chemical bonds.
However, not every electron belongs to an atom. A chemical bond or molecule can only be created by the electrons that are found in the outermost shell. Valence electrons are the name given to this sort of electron.
Therefore the correct option is D.

What is the pH of
0.000519 M NaOH?
The pH of the sodium hydroxide (NaOH) solution at the given concentration of 0.000519 M is determined as 10.72.
What is pH of solution?
The pH of a solution is defined as the logarithm of the reciprocal of the hydrogen ion concentration [H+] of the given solution.
Concentration of the basic solution, [OH⁻] = 0.000519
pOH = -log[OH⁻]
pOH = -log[0.000519]
pOH = 3.28
pH of the solutionpH + pOH = 14
pH = 14 - pOH
pH = 14 - 3.28
pH = 10.72
Thus, the pH of the sodium hydroxide (NaOH) solution at the given concentration of 0.000519 M is determined as 10.72.
