Hi!
Why is second ionization energy larger than first ionization energy?
The reason second ionization energy is larger is because it takes more energy to remove an electron from a poistively charged ion than it does from an neutral atom.
Answer:
5mL of 6 M HCl is needed to make 100 mL of 0.3 M of HCl.
Explanation:
Using the dilution formula:
M1V1 = M2V2
M1 = 0.30 M
V1 = 100 mL
M2 = 6.0 M
V2 = unknown
Re-arranging the formula by making V2 the subject of the equation:
V2 = M1V1 / M2
V2 = 0.30 * 100 / 6
V2 = 5 mL
The volume of 6 M of HCl needed to make 0.3 M at 100 mL is 5 mL.
Atom is the
most basic unit of matter. They are the general term used to describe pieces of
matter. But a different kind of atom makes up an element. A combination of atom of different elements
creates a molecule. For example, you have water; it has a chemical formula of
H2O. If you separate H from O, you have two atoms. Two atoms for hydrogen and
one atom for oxygen. However, they are of different elements. And when you
combine them to form H2O, you create a molecule.

The simplest ratios compare only two values, but ratios comparing three or more values are also possible. In any situations in which two or more distinct numbers or quantities are being compared, ratios are applicable. By describing quantities in relation to each other, they explain how chemical formulas can be duplicated or recipes in the kitchen expanded.
Please let me know if I’m wrong
Distance = 556 km
Time = 3.4 h
Speed = Distance / Time = 556 / 3.4 = 163.52 km/h
