A intense property of substance is a physical quantity.
Answer:
Well, really, it says <em>in your words, </em>so you should really be answering this on your own, but see below for what my answer would be.
Explanation:
Solubility is the ability of something to be dissolved, especially in water. Something with high solubility, such as salt, easily and quickly dissolves in a glass of water, and something with low solubility, such as oil, will take a long time to dissolve in water, or as in the case of oil, it may not dissolve at all.
3.23 x 10²³ atoms
Explanation:
Given parameters:
Volume of Argon atoms = 12L
Condition = STP
Unknown:
Number of atoms = ?
Solution:
We start from the known to the unknown. We know the volume of gas at STP to be 12L;
using the equation below, we can solve for the number of moles and find the amount of atoms.
Number of moles = 
Number of moles = 
= 0.54mole
1 mole of substance contains 6.02 x 10²³ atoms
0.54 mole will contain 6.02 x 10²³ x 0.54 = 3.23 x 10²³ atoms

Answer:
1st one is...
Explanation:
The 1st one is change in size or shape. 2nd one is formation of precipitate. 3rd one is physical change. 4th one is formation of gas.
As the building blocks of proteins , amino acids are linked to almost every life process, but they also have key roles as precursor compounds in many physiological processes.
