Which is an example of a reduction?.

Answers

Answer 1

An example of a reduction is the conversion of iron(III) oxide (Fe₂O₃) to iron metal (Fe) by the addition of hydrogen gas (H₂).

The reaction can be represented as follows:

Fe₂O₃ + 3H₂ → 2Fe + 3H₂O

In this reaction, iron(III) oxide is reduced to iron metal, and hydrogen gas is oxidized to water. Reduction involves the gain of electrons or a decrease in the oxidation state of an atom or molecule. In this case, the iron(III) ions in Fe₂O₃ gain electrons and undergo a reduction process, resulting in the formation of elemental iron.

Hence, the example of reduction is stated above.

A compound consisting of carbon and hydrogen consists of 67.90%
carbon by mass. If the compound is measure to have a mass of 37.897
Mg, how many grams of hydrogen are present in the compound?

Answers

Given that the compound consists of 67.90% carbon by mass and has a total mass of 37.897 Mg, we can calculate the mass of hydrogen in the compound.

Let's assume the mass percentage of hydrogen in the compound is denoted by "y." According to the law of constant composition, the sum of the mass percentages of carbon and hydrogen is equal to 100.

Mass% of Carbon + Mass% of Hydrogen = 100

Since the mass percentage of carbon is 67.90%, we can calculate the mass percentage of hydrogen as follows:

Mass% of Hydrogen = 100 - 67.9

Mass% of Hydrogen = 32.1

Therefore, the compound contains 32.1% of hydrogen by mass.

Next, we can calculate the mass of hydrogen present in the compound using the following formula:

Mass of hydrogen = Percentage of hydrogen x Total mass of the compound / 100

Substituting the given values, we find:

Mass of hydrogen = 32.1 x 37.897 Mg / 100

Now, we need to convert the mass from megagrams (Mg) to grams:

Mass of hydrogen = 32.1 x 37.897 Mg x 10^6 g / 100

Calculating this expression, we find:

Mass of hydrogen = 12.159 grams

There are 12.159 grams of hydrogen present in the compound.

a piece of magnesium metal gradually forms an outside layer of magnesium oxide when exposed to the air. the class of this reaction is

Answers

The class of the reaction between magnesium metal and oxygen in the air, which results in the formation of magnesium oxide, is oxidation.

Oxidation is a chemical reaction that involves the loss of electrons or an increase in oxidation state. In this case, magnesium metal (Mg) undergoes oxidation as it reacts with oxygen (O_2) in the air. The magnesium atoms lose electrons, transferring them to the oxygen atoms, resulting in the formation of magnesium oxide (MgO).

Magnesium metal is highly reactive and readily oxidizes in the presence of oxygen. The outer layer of magnesium metal reacts with oxygen molecules to form magnesium oxide. This process occurs gradually over time as magnesium atoms on the surface of the metal react with oxygen.

The formation of magnesium oxide is a classic example of an oxidation reaction, where magnesium undergoes oxidation by losing electrons, and oxygen undergoes reduction by gaining electrons. This type of reaction is commonly observed in the corrosion of metals when they are exposed to air or other oxidizing agents.

The density of titanium is 4.51g/cm^3. What is the volume (in
cubic inches) of 3.5lb of Titanium? this could be helpful D=M/V

Answers

The volume of 3.5 lb of titanium is 21.47 in³.

The density of titanium is 4.51 g/cm³.The weight of titanium is 3.5 lb.

Formula used:

Density, D = M/V, where D is density, M is mass, and V is volume.

The conversion factor of 1 inch³ = 16.39 cm³.1 lb = 453.592 g.

First, we will calculate the mass of titanium.

3.5 lb = 3.5 × 453.592 g

= 1587.772 g

Next, we will calculate the volume of titanium.

Volume of titanium = Mass of titanium / Density of titanium

= 1587.772 g / 4.51 g/cm³

= 352.044 cm³

Next, we will convert the volume from cm³ to in³.

1 inch³ = 16.39 cm³.

Volume of titanium in in³ = Volume of titanium / 16.39

= 352.044 cm³ / 16.39

= 21.47 in³
