What biological factors and/or actions contribute to increases in entropy?

Chemistry
1 answer:
vlada-n [284]2 years ago
3 0

Answer:

If you increase temperature, you increase entropy. (1) More energy put into a system excites the molecules and the amount of random activity. (2) As a gas expands in a system, entropy increases.

Electronegativities of the elements Na, Al, P, and Cl follow a specific trend across the period. Based on this trend, an electro
Vitek1552 [10]

Answer:

Electronegativity increases across the period on a periodic table.

Explanation:

Electronegativity is the ability of an atom to attract electron to itself.

All elements on the periodic table combines in order to have a complete octet i.e they all want to be like the noble gases, group 0 elements.

This is what drives most atom to combine chemically. By so doing, they either lose or gain electrons.

Cl belongs to the 7th group on the periodic table. It is the second element in this halogen group. Most halogens are notable for their high electronegativity. They have 7 electrons in their outermost shell and would require just an electron to complete their octet.

This makes them highly reactive and combine readily with other elements.

The halogens have a strong attraction for valence electrons. The higher the electronegativity value, the stronger the attraction an atom has for valence electrons.

Most metals like Al and Na are electropositive and readily donates or lose electrons so as to have a complete octet.

Simora [160]

Answer:

Mg(s) + Sn²⁺(aq) ⇄ Mg²⁺(aq) + Sn(s)

Explanation:

Let's consider the following molecular equation.

Mg(s) + SnSO₄(aq) ⇄ MgSO₄(aq) + Sn(s)

The full ionic equation includes al the ions and the species that do not dissociate in water.

Mg(s) + Sn²⁺(aq) + SO₄²⁻(aq) ⇄ Mg²⁺(aq) + SO₄²⁻(aq) + Sn(s)

The net ionic equation includes only the ions that participate in the reaction (not spectator ions) and the species that do not dissociate in water.

Mg(s) + Sn²⁺(aq) ⇄ Mg²⁺(aq) + Sn(s)
