The chlorine anion is a Lewis base.
The chlorine anion is a donor of electronic pair:

Cl⁻ + H⁺ → HCl

As chlorine has seven electrons in its outer most shell so to complete its octet it has to gain an electron and when it gain an electron it will become an anion that is negatively charged
so in my opinion and what a conclude is that the option B is correct for the above statement

elements combine in three general ways. in blank compounds, electrons are transferred from one element to the other, whereas in

hichkok12 [17]

Elements combine in three general ways. In ionic compounds, electrons are transferred from one element to the other, whereas in covalent compounds, electrons are shared between atoms. Third, in metallic bonding, electrons are shared between a large number of atoms in an electron sea.

Ionic compounds are compounds in which a free electron is transferred to another atom and a bond is formed. Ionic bonds occur in metal ions.

In liquid compounds, covalent bonds are formed. In covalent bonds, electrons are shared with each other,

The third type of bond is the metallic bond. In this type of bond, atoms are packed tightly and a free electron pool travels in between them.

What is the value for AG at 100 K if AH = 27 kJ/mol and AS = 0.09 kJ/mol.K)?

Aleonysh [2.5K]

The value for ΔG = 18 kJ/mol

<h3>Further explanation</h3>

Given

ΔH = 27 kJ/mol and ΔS = 0.09 kJ/mol.K

T = 100 K

Required

the value for ΔG

Solution

The spontaneous process of a reaction is based on 2 factors :

enthalpy change ΔH decreases and
entropy change ΔS increases

ΔG=ΔH-T.ΔS

$\tt \Delta G=27~kJ/mol-100\times 0.09~kJ/mol.K\\\\\Delta G=18~kJ/mol$

A true statement about mass is that:

Orlov [11]

Answer:

(c.) as the force of Earth's gravity on an object increases, the object's mass increases

Explanation:

Based on newton's law of gravitation "every particle of matter in the universe attracts every other particle with a force that is directly proportional to the product of the masses of the particles and inversely proportional to the square of the distance between them".

It is mathematically expressed as:

F = $\frac{Gm_{1} m_{2} }{r^{2} }$

F is the gravitational force on either particle

m₁ and m₂ are the masses

r is the distance between particles

G is the universal gravitation constant.

From this expression, we see that the force of earth's gravity is directly proportional to mass.

a student used 10 mL water instead of 30 mL for extraction of salt water from mixture. how may this change the percentage of NaC

ch4aika [34]

If a student used 10 mL water instead of 30 mL for extraction of salt water from mixture, the extraction of salt will be lesser than compared to using 30 mL since less solute will dissolve in 10 mL.
