Answer:
I think it's b.
Explanation:
Because solubility increased by temperature.
The answer is, "In an atom, protons and neutrons are in the nucleus, which is surrounded by electrons."
So the false statement that is In an atom, protons and electrons are in the nucleus, which is surrounded by neutrons, can be made true by rewording it as, "In an atom, protons and neutrons are in the nucleus, which is surrounded by electrons.
Answer:
Examples of substances insoluble in water: oil, acetone, ether
Explanation:
Such examples of substances are non-polar and do not dissolve in water (polar compound). The classic example is oil floating in water (this happens because oil has a lower density than water).
Answer:
cells are too small to see with the naked eye and a microscope magnifies them
Explanation:
Number of moles = 2.25 mols
volume <span>of the solution = 3.00 L
</span>
Therefore :
molarity = moles / volume
m = 2.25 / 3.00
=> 0.75 M
