Answer:
The best definition is: "Buffer capacity is the amount of acid or base that can be added to a buffer without destroying its effectiveness"
Explanation:
A buffer is a solution that is somewhat resist to pH changes by reacting with acids and bases that may be added into the solution. It's capacity is the amounto of acid or base that can be added into solution without much change in pH.
So the best definition is: "Buffer capacity is the amount of acid or base that can be added to a buffer without destroying its effectiveness"
Answer:
48 g S
Explanation:
Step 1: Define
Molar Mass of Sulfur (S) - 32.07 g/mol
Step 2: Use Dimensional Analysis
= 48.105 g S
Step 3: Simplify
We have 2 sig figs.
48.105 g S ≈ 48 g S
Energy cannot be created or destroyed, so the answer would be c.) not a or b.
Hope this helps!
The correct option is (e) 0.389 moles.
The number of moles represented by 21.7 g fe 0.389 moles.
Solution:
(21.7g) x (1mol/55.85g) = 0.389 moles
<h3>What is moles?</h3>
The mole, represented by the symbol mol, is the fundamental SI unit of material quantity. The amount of a substance determines how many elementary entities of that substance are present in an object or sample. Since the SI fundamental units were revised in 2019, the mole is now exactly defined as 6.022140761023.
<h3>Why the mole is a base unit?</h3>
The amount of a substance determines how many elementary entities of that substance are present in an object or sample. Since the SI fundamental units were revised in 2019, the mole is now exactly defined as 6.022140761023.

B) proton
electrons are in a cloud around it, ions are elements with a charge, idk what a free radical is but ik that protons and neutrons are inside the nucleas
