Living organisms contain relatively large amounts of oxygen, carbon, hydrogen, nitrogen, and sulfur (thesefive elements are known as the bulk elements), along with sodium, magnesium, potassium, calcium, chlorine, and phosphorus (these six elements are known as macrominerals).

Answer: the mixing of ones s and two p atomic orbitals
Explanation: hope it helps ;)
Number of molecules = moles x avogadros constant so 1 x 6.02x10^23 = 6.02x10^23
O2 has two atoms therefore you times your answer by 2 making it
= 1.204x10^24
Answer:
Control
Explanation:
A scientific control represents an experimental condition that scientists set up to be able to properly interpret their results. A control is used to minimize variation in the results.
For example, in this experiment studying plant growth, it could have been particularly cloudy during the experiment, meaning sunlight might have been unusually low. If we didn't have the control, we wouldn't be able to tell if any changes in growth were a result of the cloudiness, or because of what we did during our experiment. Having a "normal" control allows us to compare our results within the experiment.
