Answer:
because electron is a negetively charge particle that orbits the outer part of atom and despite being small it is a strong proton.
Explanation:
Molarity = moles/solutions in litres
molarity = 8.0/0.12
molarity = 66.66
The periodic table is an important but rather dry scientific tool. It lists all the chemical elements, ordered by their atomic numbers. Elements with similar behavior are grouped in the same column (called a group), with metals generally on the left and non-metals (gases) on the right. Rows are called “periods” - hence, periodic table.

PH +pOH = 14
(14 - 11.5) = 2.5 (the ph is 2.5)
NOW, Ph = -lg (H*)
apply the formula
Answer:
9.4 mL.
Explanation:
To accurately determine the reading of the graduated cylinder, we simply take the reading under the curve (i.e meniscus)
From the above diagram, we can see that the reading under the curve is 9.4 mL.
Therefore, the reading of the cylinder is 9.4 mL
