<span>a. x and y are atoms of the same element. 

If both atoms contain the same amount of protons, they are always the same element.

Answer:

a. X and y are atoms of the same element.

Explanation:

We conclude that the a. It is the right choice because for X and Y to be isotopes, they must have different numbers of neutrons in the nucleus.

X and Y have the same number of neutrons in the nucleus 14

In this case, X is an ion because it does not have the same number of protons in the nucleus as electrons, therefore it is charged (positively in this case)

And it has the same number of protons and electrons, therefore, it is electrically neutral.

the electronic configuration of Y is [Ne] 3s^2 3p^2

the electronic configuration of Y is[Ne] 3s^2 3p^1

to have a full shell the electrons in the sublayer <em>p</em> should be 6

If 24.1 g of sodium hydroxide react with 22.0 g of hydrochloric acid to form 35.3g
disa [49]

Answer:

10.85 g of H2O.

Explanation:

We'll begin by writing the balanced equation for the reaction. This is given below:

NaOH + HCl —> NaCl + H2O

Next, we shall determine the mass of NaOH that reacted and the mass of H2O produced from the balanced equation.

These can be obtained as illustrated below:

Molar mass of NaOH = 23 + 16 + 1 = 40 g/mol

Mass of NaOH from the balanced equation = 1 × 40 = 40 g

Molar mass of H2O = (2×1) + 16 = 2 + 16 = 18 g/mol

Mass of H2O from the balanced equation = 1 × 18 = 18 g

Summary:

From the balanced equation above,

40 g of NaOH reacted to produce 18 g of H2O.

Finally, we shall determine the mass of water, H2O produced from the reaction as follow:

From the balanced equation above,

40 g of NaOH reacted to produce 18 g of H2O.

Therefore, 24.1 g of NaOH will react to produce = (24.1 × 18)/40 = 10.85 g of H2O.

Therefore, 10.85 g of H2O were produced from the reaction.
