I can’t read ? This what does it say
The unequal sharing of electrons gives the water molecule a slight negative charge near its oxygen atom and a slight positive charge near itshydrogen atoms. When a neutral molecule has a positive area at one end and a negative area at the other, it is a polar molecule.
Answer:
<h2>9.26 L</h2>
Explanation:
The density of a substance can be found by using the formula

From the question we have

We have the final answer as
<h3>9.26 L</h3>
Hope this helps you
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!!!!
