Describe how a positive result for the Baeyer Test will look. What is being oxidized? What is being reduced?

Chemistry
1 answer:
Ksivusya [100]2 years ago
5 0

Answer:

This reaction is sometimes referred to as the Baeyer test. Because potassium permanganate, which is purple, is reduced to manganese dioxide, which is a brown precipitate, any water‐soluble compound that produces this color change when added to cold potassium permanganate must possess double or triple bonds.

Antimony pentafluoride has a formula of SbF5. What is the percent composition of Sb in this molecule
Akimi4 [234]

Answer:

56.17% is percent composition of Sb in the molecule

Explanation:

Percent composition is the percent in mass of each element present in a particular molecule.

In SbF₅, there is 1 mole of Antimony -Molar mass: 121.76g- per 5 moles of fluorine -Molar mass: 19g/mol-. In a basis of 1 mole, the mass of Sb and F is:

<em>Mass Sb:</em>

1mol * (121.76g/mol) = 121.76g

<em>Mass F:</em>

1 mol SbF₅ = 5 moles F * (19g / mol) = 95g

<em>Total mass:</em>

121.76g + 95g = 216.76g

And percent composition of Sb:

121.76g / 216.76g * 100 =

<h3>56.17% is percent composition of Sb in the molecule</h3>

explain how one and two letters chemical symbols are used to identify elements whose names begin with the same letter, for examp
Nadusha1986 [10]

The symbol of helium is He and this distinguishes it from the symbol for hydrogen.

<h3>What are chemical symbols?</h3>

Chemical symbol are the means by which we designate elements on paper. The symbols could be one letter or two letter as the case may be. There is no chemical symbol that has more than two letters that are used to designate the element.

We know that hydrogen has the symbol H. There is to way that another element will also have the symbol H as that would be tantamount to confusion. As a result of that, the symbol of helium is He and this distinguishes it from the symbol for hydrogen.

You wish to make a 0.285 M hydroiodic acid solution from a stock solution of 12.0 M hydroiodic acid. How much concentrated acid
Inessa05 [86]

The amount, in mL, of the concentrated acid required, would be 1.1875 mL

<h3>Dilution</h3>

From the dilution equation:

m1v1=m2v2 where m1 and m2 = molarity before and after dilution, and v1 and v2 = volume before and after dilution.

m2 = 0.285M, m1 = 12.0M v2 = 50.0 mL

v1 = m2v2/m1 = 0.285x50/12 = 1.1875 mL

Thus, 1.1875 mL of the acid would be taken and diluted with water up to the 50 mL mark.
