Can someone help me with this! I need it ASAP! I don’t understand

Archy [21]

Answer:

The answer to your question is:

Explanation:

1) Increasing atomic radius:

Oxygen 74

Aluminum 143

Potasium 227

2) Increasing electronegativity

Neon -

Aluminum 1.61

Sulfur 2.58

Oxygen 3.44

3.-

Electronegativity: is the measure of the tendency of an atom to attract a pair of electrons.

Ionization energy: is the quantity of energy that an isolated, gaseous atom must absorb to discharged an electron, resulting in a cation.

4.-

Atomic radius increases as we move down on the periodic table.

Atomic radius is the distance from the center of a nucleus to the outer most shell containing electrons.

5.-

Sulfur = 1s² 2s² 2p⁶ 3s² 3p⁴

Neon = 1s² 2s² 2p⁶

Some scientists believe that life on Earth may have originated near deep-ocean vents. Balance the following reactions, which are

goldenfox [79]

Answer :

(1) The balanced chemical reaction will be,

$2CH_3SH(l)+CO(g)\rightarrow CH_3CO(SCH_3)(l)+H_2S(g)$

(2) The balanced chemical reaction will be,

$8H_2S(g)+8CO(g)\rightarrow 4CH_3CO_2H(g)+S_8(s)$

Explanation :

Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.

If the amount of atoms of each type on the left and right sides of a reaction differs then to balance the equation by adding coefficient in the front of the elements or molecule or compound in the chemical equation.

The coefficient tell us about that how many molecules or atoms present in the chemical equation.

(1) The unbalanced chemical reaction is,

$CH_3SH(l)+CO(g)\rightarrow CH_3CO(SCH_3)(l)+H_2S(g)$

This reaction is an unbalanced chemical reaction because in this reaction number of hydrogen, sulfur and carbon atoms are not balanced.

In order to balance the chemical equation, the coefficient '2' put before the $CH_3SH$ and we get the balanced chemical equation.

The balanced chemical reaction will be,

$2CH_3SH(l)+CO(g)\rightarrow CH_3CO(SCH_3)(l)+H_2S(g)$

(2) The unbalanced chemical reaction is,

$H_2S(g)+CO(g)\rightarrow CH_3CO_2H(g)+S_8(s)$

This reaction is an unbalanced chemical reaction because in this reaction number of hydrogen, sulfur and carbon atoms are not balanced.

In order to balance the chemical equation, the coefficient '8' put before the $H_2S\text{ and }CO$ and the coefficient '4' put before the $CH_3CO_2H$ we get the balanced chemical equation.

The balanced chemical reaction will be,

$8H_2S(g)+8CO(g)\rightarrow 4CH_3CO_2H(g)+S_8(s)$
