Weed and water and maybe cheese sticks
Answer:
The answer is 2.20 M
Explanation:
This is because ammonia has a pH of 11.8 and if you take 14-11.8 it equals 2.2 so the answer is 2.20 M
Answer:
2.50 g of AlCl3
Explanation:
Goodness, stoichiometry...
So, what we need to find first is the amount of grams of AlCl3. To do this we look at the formula of molarity.
M = mols/L of solvent
So we know two parts of this formula. We have the Molarity (0.150) and the mL (125).
Now, we can't forget that we must convert 125 mL into liters so we have 0.125 L ( I forgot and had to do the entire problem again...)
So if we do the backwards equation we get:
0.150 = x/0.125
If we do math (fun ikr) we get 18.75 mols of the solution.
Now, we have to plug this wonderful number into stoichiometry
<u>0.01875 mols | 133.5 g</u>
<u>| 1 mol AgCl3</u>
If you are unfamiliar with what I'm doing, I'm basically going to multiply 0.01875*133.5 then divide that whole thing by 1.
So, I got 2.503125 g AlCl3
If your teacher is a stickler for significant figures there are 3 sig figs for this problem so your final answer should be
2.50 g of AlCl3
Hope you have a great day and fun with chemistry!!!!
The Big Bang theory is an infamous cosmological model that explains the origin universe <span>and its evolution through time. </span>The model verifies the fact that the universe originated <span>from the expansion of a highly dense and high temperature condition. This is used to explain other phenomena such as the emergence of light elements, and other cosmic events</span>
Answer:
P(N₂) = 4.02 atm
Explanation:
Number of moles of O₂ = 4 mol
Number of moles of N₂ = 8 mol
Total pressure = 6 atm
Partial pressure of N₂ = ?
Solution:
We will calculate the partial pressure by using mole friction.
P(N₂) = X(N₂)P(total)
X(N₂) = mol friction = moles of N₂ / total number of moles
X(N₂) = 8 mol / 12 mol = 0.67
Partial pressure of N₂:
P(N₂) = X(N₂)P(total)
P(N₂) = 0.67 × 6 atm
P(N₂) = 4.02 atm
