Answer:
A) As < N < F
Explanation:
Ionization energy refers to the minimum amount of energy required to remove an electron from a gaseous atom r in.
The genera trend of IE, is that it increases across the period from left to right and decrease down the group in a periodic table.
As belongs to period 4, this means it as the lowest ionization energy.
Nitrogen and Florine belong to the same period however Florine has a higher ionization energy.
In order of increasing IE;
As < N < F
Answer:
Cranberry juice is a homogeneous mixture.
Explanation:
Cranberry juice is a clear, red liquid. It is a homogeneous mixture, because you can't see a boundary between the water and the dissolved red substances dissolved in the water.
A is wrong. In oatmeal with raisins, you can tell the raisins from the oatmeal (see below).
C is wrong. Milk is a suspension of fat globules in an aqueous solution of other substances
D is wrong. Pepsi in an unopened bottle is a homogeneous, clear brown aqueous solution of carbon dioxide, high fructose corn syrup, and other substances.
Answer:
The atomic mass of an atom is the number of protons plus neutrons.
Fact: In case you get it confused with atomic number, atomic number is the number of protons in the atom.
Explanation: It could have been electrons plus neutrons since electrons equals protons but electrons aren't stable which is why it is protons and neutrons.
Answer:
= 4
Explanation:
The pH of a solution is given by;
pH = - log [H+] , while
pOH = - log [OH-]
But; pH + pOH = 14
Therefore;
pH = 14 - pOH
= 14 - 10
= 4
The process of splitting an atomic into 2 nuclei with smaller masses is called fission
the elements in group 18mall have 6 valance electrons
