An atom is the smallest unit of ordinary matter that forms a chemical element.
oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus.
The last one will be It's better to use the average data instead of the single trail because the average you don't have to multiply add subtract and all that nonsense but if you use the single trail you will have to do all the adding multiplying etc.
Sedimentary rocks. Not sure though
The mole fraction of acetone (C₃H₆O) is 0.333
<h3>Data obtained from the question </h3>
- Mole of C₃H₆O = 0.1 mole
- Mole of CHCl₃ = 0.2 mole
- Mole fraction of C₃H₆O =?
<h3>How to determine the mole fraction </h3>
Mole fraction of a substance can be obtained by using the following formula:
Mole fraction = mole / total mole
With the above formula, we can obtain the mole fraction of C₃H₆O as follow:
- Mole of C₃H₆O = 0.1 mole
- Mole of CHCl₃ = 0.2 mole
- Total mole = 0.1 + 0.2 = 0.3 mole
- Mole fraction of C₃H₆O =?
Mole fraction = mole / total mole
Mole fraction of C₃H₆O = 0.1 / 0.3
Mole fraction of C₃H₆O = 0.333

Answer:
H₂SO₄ (aq) + 2LiOH (aq) ⇒ Li₂SO₄ (aq) + 2H₂O (l)
Explanation:
This is an acid-base reaction, so we know the products are going to a salt/ionic compound and water.
