Answer: The answer is D. This has a Carboxylic Acid group, and is acetic acid, or Ethanoic Acid.

ALWAYS LOOK for the Functional Group in question.

A. Would likely not stay in water, or at least not be acidic, for it is butane gas.

B. Is 1-propanol, and alcohols are not acidic as a rule. Certainly not in water.

C. This is an Ether. It will not give up an H+, it it not an acid.

E. This functional group is an amine, which is more “base” like, since the lone pairs of the Nitrogen atom would tend to attract a H+.

In alpha and beta decay the parent element and the daughter element can be

Angelina_Jolie [31]

In alpha and beta decay the parent element and the daughter element will be different isotope and not the same.
This is because as alpha particles comes out; the new element will have two less in atomic number; that is the atomic number will reduce by two and the mass number will reduce by four. While in a beta particle decay, the new element will have one higher in atomic number; that is the atomic number will increase by one.

vladimir2022 [97]

Answer:

ii) the energy of the electron on the outer shell

iv) the overall size of an orbital

Explanation:

There are four quantum numbers to define the position and energy level of an electron in an atom

a) Principal : The principal quantum number (n) is to know the energy of an electron in an atom and its possible distance from the nucleus.

b) Azimuthal: It refers to the shape of the subshell or orbital of the electron and thus the angular distribution.

c) Magnetic: It refers to the number of orbits and their orientation in the subshell.

d) spin: It refers to the spin of the electron.

#15 fill in the following table regarding ions

Natasha_Volkova [10]

Answer:

$P^{3-}$ Anion Gained 3 18

$Sr^{2+}$ Cation Lost 2 36

$Fe^{3+}$ Cation Lost 3 23

Explanation:

Looking at the ionic notation, the negative symbol (-) indicates that there are more electrons than protons and the positive symbol (+) indicates that there are more protons than electrons.

The number tells you how many was gained or lost.

To determine how many electrons are left, you base this off how many protons there are. The number of protons in an atom is expressed by the atomic number. In a stable atom, you have an equal number of protons and electrons.

Ions occur when electrons are gained or lost.

A cation is positively charged because it LOST an electron. Since there are more protons than electrons, the charge would be positive.

An anion is negatively charged because it gained an electron. Since there are more electrons than protons, the charge would be negative.

Using the explanation above, you can see how the answers were obtained. As for the last column, just use basic math to do this.

The atomic number of Phosphorus (P) is 15, so this means that there are 15 protons. Since it gained 3 electrons, just add 3 to 15:

15 + 3 = 18

Sr has an atomic number 38. Since it lost 2 electrons, just subtract 2 from the atomic number.

38-2 = 36

Fe has an atomic number 26. It lost 3 electrons, so we subtract again.

26-3 = 23
