Answer:

nertial mass is a measure of how difficult it is to change the velocity of an object. Example. Calculate the force needed to accelerate a 22 kg cheetah at 15 m/s².

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 $XSO_3$

Select the correct term to complete each sentence.

leva [86]

Answer: 1. halve

2. halve

3. double

Explanation:

The relationship between wavelength and energy of the wave follows the equation:

$E=\frac{hc}{\lambda}$

E= energy

$\lambda$ = wavelength of the wave

h = Planck's constant

c = speed of light

Thus as wavelength and energy have inverse realation, when wavelength will halve , energy will double.

2. The between wavenumber and energy of the wave follows the equation:

$E=h\times c\times \bar{\nu}$

E= energy

$\bar{\nu}$ $\nubar$ = wavenumber of the wave

h = Planck's constant

c = speed of light

Thus as wavenumber and energy have direct relation, when wavenumber will halve , energy will be halved.

3. The relationship between energy and frequency of the wave follows the equation:

$E=h\times \nu$

where

E = energy

h = Planck's constant

$\nu$ = frequency of the wave

Thus as frequency and energy have direct realation, when frequency will double , energy will double.

Try moving an electron from the metal to the nonmetal. What happens?

skad [1K]

Answer:

Explanation:

When electron is transfer from metal to non metal anion and cations are formed and compound formed is called ionic compound.

Ionic bond:

It is the bond which is formed by the transfer of electron from metal to the atom of non metal.

Both bonded atoms have very large electronegativity difference. The atom with large electronegativity value accept the electron from other with smaller value of electronegativity thus the atom which accept the electron is form anion and metal atom which lose the electron is form cation .

For example:

Sodium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the chlorine. Sodium becomes positive and chlorine becomes negative ion the compound form is called sodium chloride.
