If you are provided with Cation and an Anion with different oxidation states, then there ratio in the formula unit is adjusted as such that the oxidation number of one ion is set the coefficient of other ion and vice versa,

Example:
               Let suppose you are provided with A⁺² and B⁻¹, so multiply A by 1 and B by 2 as follow,
                                                      A(B)₂

In statement we are given with Co⁺³ and SO₄⁻², so multiply Co⁺³ by 2 and SO₄⁻² by 3, hence,

                                                  Co₂(SO₄)₃

Result:
           Co₂(SO₄)₃ is the correct answer.

What type of compound results from the reaction of an acid chloride and a 2° amine?
Butoxors [25]

Amide is produced when a 2° amine and an acid chloride combine.

Acid chloride: What is it?

  • The chemical name for acid chloride is RCOCl, where "R" stands for a side chain. They are reactive derivatives of carboxylic acids. In organic chemistry, an acyl group and a chlorine atom form an organic molecule known as an acyl chloride (also known as acid chloride).
  • A functional group identified by the RCO molecular formula is called an acyl group. Since acyl chlorides are often hazardous, handling them requires extra care.
  • They have the potential to produce HCl and organic compounds when they interact with water on the surface of the eye, irritating the eye. Anhydrous acid salts are neutral because it lacks an H+ donor.

To determine the freezing point depression of a LiCl solution, Toni adds 0.411 g of LiCl to the sample test tube along with 19.7
Cerrena [4.2K]

Answer:

LiCl = 0.492 m

Explanation:

Molal concentration is the one that indicates the moles of solute that are contained in 1kg of solvent.

Our solute is lithium chloride, LiCl.

Our solvent is distilled water.

We do not have the mass of water, but we know the volume, so we should apply density to determine mass.

Density = mass / volume

Density . volume = mass

1 g/mL . 19.7 mL = 19.7 g

We convert g to kg → 19.7 g . 1 kg / 1000g = 0.0197 kg

Let's determine the moles of LiCl

0.411 g . 1 mol / 42.394 g = 9.69×10⁻³ moles

Molal concentration (m) = 9.69×10⁻³ mol / 0.0197 kg → 0.492 m
