Answer:
3.6 × 10²⁴ atoms of O
Explanation:
Let's consider the molecular formula of silver nitrate: AgNO₃.
We can establish the following relations:
- 1 mol of AgNO₃ has 6.02 × 10²³ molecules of AgNO₃ (Avogadro's number).
- 1 molecule of AgNO₃ has 3 atoms of oxygen.
The atoms of oxygen in 2.0 moles of silver nitrate are:
Your answer is, all of the above.
<u>Chemical Change </u>
A chemical change occurs on the molecular level and produces a new substance. However, a physical change rearranges molecules and does not produce a new substance.
<u>10 examples of chemical changes</u>
- Burning of paper and log of wood
- Various metabolic reactions that take place in the cells
<u> Impacts of Chemical changes</u>
Anytime a new substance is made, a chemical change takes place. Usually two or more materials are combined and a new substance is formed. A chemical change can produce amazing explosions, like fireworks.
Thus, <u>all of the above</u> is the correct answer. Learn more about "Chemical Changes" here
