What is the name of this molecule?

Neko [114]

The triple bond is in the first place, not the 3rd because we have to choose the smallest possible number. That means the name will be: ‘but-1-yne’ or ‘1-butyne’

the first three ionization energies of an element x are 590, 1145, and 4912 kj mol-1. what is the most likely formula of the com

joja [24]

<u>Answer:</u> The chemical formula is $XSO_3$

<u>Explanation:</u>

Ionization energy is defined as the amount of energy that is required to remove an electron from a chemical species.

The ionization energy equation for the given values follow:

$X(g)\rightarrow X^+(g)+e^-;E_I=590kJ/mol$

$X^+(g)\rightarrow X^{2+}(g)+e^-;E_I=1145kJ/mol$

$X^{2+}(g)\rightarrow X^{3+}(g)+e^-;E_I=4912kJ/mol$

From the values of ionization energy above, it can be seen that the ionization energy increases as every succeeding electron is removed.

Second ionization energy is a little higher than the first one but there is a huge amount of difference between the third and second ionization energy.

This implies that the ion formed during second ionization energy has a stable configuration and it requires a humongous amount of heat to release the third electron.

Hence, the ion formed will be $X^{2+}$

Sulfite ion is a polyatomic ion having a chemical formula of $SO_3^{2-}$

An ionic compound is formed between the two ions and the chemical compound formed between the two will have a formula of $XSO_3$

Hence, the chemical formula is $XSO_3$

A beaker contains 0.125 L of a 3.00 M solution. If the volume goes up to 0.325 L, what is the new molarity?

igor_vitrenko [27]

Answer:

1.15 M

Explanation:

Step 1: Given data

Initial volume (V₁): 0.125 L

Initial concentration (C₁): 3.00 M

Final volume (V₂): 0.325 L

Final concentration (C₂): ?

Step 2: Calculate the final concentration of the solution

We want to prepare a dilute solution from a concentrated one by adding water. We can calculate the concentration of the dilute solution using the dilution rule.

C₁ × V₁ = C₂ × V₂

C₂ = C₁ × V₁/V₂

C₂ = 3.00 M × 0.125 L/0.325 L = 1.15 M
