When magnesium combines with sulfur to form magnesium sulfide, it is oxidized to Mg2+. Which statement is true about this reacti

Vlad1618 [11]

<h3>Answer;</h3>

B. It involves loss of electrons.

<h3>Explanation;</h3>

Oxidation occurs when electrons are lost by an atom while reduction refers to the gain of electrons by an atom.
In this case, magnesium atom reacts with sulfur to form magnesium sulfide by loosing two electrons and forming magnesium ion (Mg2+). Therefore magnesium undergoes oxidation.
Sulfur, on the other hand will gain electrons to form Sulfide ions, therefore it undergoes reduction.
Therefore; In magnesium sulfide (MgS), magnesium loses two electrons and becomes a cation with a positive-two charge. Likewise, sulfur obtains the two electrons lost from magnesium and becomes an anion with a negative-two charge. However, the overall charge of MgS is zero.

Match each of the following descriptions to thecorrect element listed

Slav-nsk [51]

Answer: Please see explanation for answer

Explanation:Matching the descriptions to the correct element listed gives

Element Group Name Group No Metal/ Nonmetal/ Metalloid Description

Neon Noble gases 18 Non metal Colorless, tasteless, and odorless gas, unreactive, nonconductive.

Bromine Halogens 17 Non metal Not found as a free element (uncombined) in nature, reddish-brown liquid that vaporizes readily at room temperature to a red gas with a strong disagreeable odor.

Beryllium Alklaline earth metal 2 Metal Silvery-white, ductile, malleable, conductive solid with a high melting point for this type of element

Platinum Platimum group metals 10 Metal Silvery white, relatively soft, low density, conductive solid that is not found as a free element in nature but commonly found combined in alloys with copper or nickel

Potassium Alkali Metals 1 Metal Soft, easily cut with a knife to expose a silvery surface that rapidly oxidizes in air; never found uncombined in nature

Silicon Carbon family 1`4 Metalloid Metallic luster and grayish solid, very common in rocks and gemstones such as amethyst and opal, semiconductor

Sulfur Calcogens 16 Non metal Pale yellow, odorless, brittle solid at room temperature, nonconductor

Activity C: Hydrolysis of Carbohydrates As discussed earlier, disaccharides are composed of two monosaccharides linked together.

adelina 88 [10]

Answer:

Sucrose: glucose and fructose

Explanation:

What monosaccharides will result from the hydrolysis of sucrose?

Sucrose is a disaccharide composed of 2 different monosaccharides: glucose and fructose joining by a 1 ⇒ 2 bond. These monosaccharides will be released upon the hydrolysis of sucrose.

What monosaccharide will result from the hydrolysis of starch?

Starch is a polysaccharide composed of numerous glucose monomers joined by glycosidic bonds (1 ⇒ 4 and 1 ⇒ 6). These monosaccharides will be released upon the hydrolysis of starch.
