Two elements have similiar characteristics when they belong to the same family that means that have placed in the same column of the periodic table. So in other words, Helium and Radon are very similar because they are in the same column. Let me know if you need others :)
Answer:
a substance made by mixing other substances together.
Explanation:
A mixture is a substance made by mixing two or more substances together.
Answer:
The answer to your question is 1.33 M
Explanation:
Data
Volume of H₃PO₄ = 24 ml
[H₃PO₄] = ?
Volume of KOH = 16 ml
[KOH] = 2 M
1 M H₃PO₄ = 3.0 M H⁺
Balanced chemical reaction
KOH + H₃PO₄ ⇒ K₃PO₄ + H₂O
Process
1.- Calculate the moles of KOH
Molarity = moles / volume
-Solve for moles
moles = Molarity x volume
-Substitution
moles = 2 x 16/1000
-Simplification
moles = 32/1000
-Result
moles = 0.032
2.- Calculate the moles of H₃PO₄
1 mol of KOH --------------- 1 mol of H₃PO₄
0.032 moles of KOH -------------- x
x = (0.032 x 1) / 1
x = 0.032 moles of H₃PO₄
3.- Calculate the concentration of H₃PO₄
Molarity = 0.032 / 0.024
-Result
Molarity = 1.33
