Answer:
because air pressure crushes masses and or grams that have a stronger gravitaional
pull
2.02 x 10²³molecules
Explanation:
Given parameters:
Mass of NH₃ = 5.7g
Unknown:
number of molecules = ?
Solution:
To solve this problem, we need to approach it from the mole point of view.
A mole of any substance is the amount that contains the avogadro's number of particles.
We first find the number of molecules in NH₃ and then proceed to find the amount of particles it contains.
Number moles =
Molar mass of NH₃ = 14 + 3(1) = 17g/mole
Number of moles = = 0.34moles
Number of molecules;
1 mole of of NH₃ = 6.02 x 10²³
0.34 moles = 0.34 x 6.02 x 10²³ = 2.02 x 10²³molecules

Answer:
Taxonomy
Explanation: Taxonomy formally names and classifies organisms by thier structure, function, and relationships
Answer:
Yes
Explanation:
Scientific laws must always be accompanied by theories. Without theories, laws cannot be formed. In other words, scientific laws are made from scientific theories.
<em>When a hypothesis has been tested by several independent researchers and found to be true, this leads to the development of a theory. A theory becomes a law when it is able to hold true against a wide range of similar phenomena.</em>
