Answer:

$8Fe_{(s)}+S_8_{(s)}\rightarrow 8FeS_{(s)}$

Explanation:

The unbalanced reaction of the reaction of Iron and sulfur is shown below as:-

$Fe_{(s)}+S_8_{(s)}\rightarrow FeS_{(s)}$

On the left hand side,

There is 1 iron atom and 8 sulfur atoms.

On the right hand side,

There is 1 iron atom and 1 sulfur atom.

Thus,

Right side, $FeS$ must be multiplied by 8 to balance the sulfur and,

Left side, $Fe$ is multiplied by 8 so to balance the whole reaction.

Thus, the balanced reaction is:-

$8Fe_{(s)}+S_8_{(s)}\rightarrow 8FeS_{(s)}$

Answer : The rate constant at 785.0 K is, $1.45\times 10^{-2}s^{-1}$

Explanation :

According to the Arrhenius equation,

$K=A\times e^{\frac{-Ea}{RT}}$

or,

$\log (\frac{K_2}{K_1})=\frac{Ea}{2.303\times R}[\frac{1}{T_1}-\frac{1}{T_2}]$

where,

$K_1$ = rate constant at $600.0K$ = $6.1\times 10^{-8}s^{-1}$

$K_2$ = rate constant at $785.0K$ = ?

$Ea$ = activation energy for the reaction = 262 kJ/mole = 262000 J/mole

R = gas constant = 8.314 J/mole.K

$T_1$ = initial temperature = $600.0K$

$T_2$ = final temperature = $785.0K$

Now put all the given values in this formula, we get:

$\log (\frac{K_2}{6.1\times 10^{-8}s^{-1}})=\frac{262000J/mole}{2.303\times 8.314J/mole.K}[\frac{1}{600.0K}-\frac{1}{785.0K}]$

$K_2=1.45\times 10^{-2}s^{-1}$

Therefore, the rate constant at 785.0 K is, $1.45\times 10^{-2}s^{-1}$

inessss [21]

Symbol "X" represents Nitrogen, phosphorus, and arsenic.as they have five valence electrons in their valance shell.

<h3>What is a Lewis notation?</h3>

A Lewis form is a completely simplified illustration of the valence shell electrons in a molecule. it's miles used to expose how the electrons are organized round man or woman atoms in a molecule. Electrons are proven as dots or for bonding electrons as a line between the 2 atoms.

Lewis systems, also known as electron-dot structures or electron-dot diagrams, are diagrams that show the bonding between atoms of a molecule, and the lone pairs of electrons that can exist within the molecule.A Lewis form is based totally at the idea of the octet rule, wherein atoms percentage electrons in order that every atom has 8 electrons in its outer shell. for example, an oxygen atom has six electrons in its outer shell.

Gizmo Student exploration feel the heat if a solute has really strong bonds between its particles , would you expect it to form

Troyanec [42]

Answer:

The temperature of the solute/solvent without any external effect would decrease.

Explanation:

As the bonding between the solute particles is really strong, therefore a large amount of energy is required to overcome these forces. So that the new bonding between the solute and solvent is created.

In order to achieve this, there will be a lot of energy required and that is through the heating process. So the solution will require energy so the solute will dissolve fully either by provision of external force i.e stirring or by heating.
