Answer: There are many strategies used to hunt and kill moths. I’ll tell you my way of hunting and killing moths.

Step-By-Step Explanation:
Morning and Afternoon: First, get a sticky trap. You can get it at Target or Walmart. Cover it with moth pheromones or anything you know that can attract the moths. The sticky trap, will stick them to the trap and will eventually die after no being able to escape for a long time.
Nighttime: Buy or Get a lamp and turn it on. This will attract lots of moths and it will help you see them. Then, spray insecticide or insect repellent at the. Lastly, they should die.
Tip: If things get too out of hand with a huge swarm of moths, then call pest control and they will surely get rid of them for you!

The equilibrium constant for the gas-phase isomerization of borneol (c10h17oh) to isoborneol at 503 k is 0.106. a mixture consis
Dimas [21]
The solution is as follows:

K = [Partial pressure of isoborneol]/[Partial pressure of borneol] = 0.106

The molar mass of isoborneol/borneol is 154.25 g/mol

Mol isoborneol = 15 g/154.25 = 0.0972 mol
Mol borneol = 7.5 g/154.25 = 0.0486 mol

Use the ICE approach

        borneol  →  isoborneol
I         0.0972           0.0486
C         -x                     +x
E     0.0972 - x        0.0486 + x

Total moles = 0.1458

Using Raoult's Law,
Partial Pressure = Mole fraction*Total Pressure
[Partial pressure of isoborneol] = [(0.0972-x)/0.1458]*P
[Partial pressure of borneol] = [(0.0486+x/0.1458)]*P

0.106 = [(0.0972-x)/0.1458]*P/ [(0.0486+x/0.1458)]*P
Solving for x,
x = 0.0832 

Thus,
<em>Mol fraction of borneol = (0.0486+0.0832)/0.1458 = 0.904</em>
<em>Mol fraction of isoborneol = (0.0972-0.0832)/0.1458 = 0.096</em>

If an element has 10 protons and 11 neutrons and 10 electrons, which expression correctly identifies the element? Atomic numbers
Bezzdna [24]

Answer:

Explanation:

Firstly, it should be noted that atomic number (number of protons) determines element. And the element with the atomic number 10 (10 protons) is Neon. Hence, Neon-10 (₁₀Ne) is the answer.

Note that sodium has an atomic number of 11. Also, number of protons is usually equal to the number of electrons in neutral atoms, this is because the total number of positive particles (protons) must be equal to the total number of negative particles (electrons) to give a neutral atom.
