all of the negative and positive molecules
Answer:
The answer is <u>C. As2O3</u>
Explanation:
0.600 gr of Arsenic and Oxygen.
0.454 gr of Arsenic
So, 0.146 gr of Oxygen will be in the compound.
- First: The grams of each element must be divided by its atomic weight:
- 0.454 gr As / 74.92u As = 0.00606
- 0.146 gr O / 16u O = 0.009125
- Both results must be divided by the lowest number found:
- 0.009125 / 0.00606 = 1.5 O
- As one of the values is not an integer then both results are multiplied until both give an integer:
- Then the answer is given:
The strength of an acid is based on the hydrogen ions it forms.
I would suggest you to use this instead.
Just place the known substance for example O2 Oxygen as they are asking you, and see where the diagram takes you.
So the answer would be 2 because you’d look at the coefficients of the balanced equation up there. H2O

Answer:
53.2 mL
Explanation:
As this problem deals with the neutralization of a strong monoprotic acid and a strong base, we can solve it by using the following formula:
Where in this case:
We <u>input the data</u>:
- 0.230 M * 74.0 mL = 0.320 M * Vb
And <u>solve for Vb</u>:
