For multiple covalent bonds to form in molecules, the molecules must contain carbon nitrogen or oxygen.

Explanation:

Think about carbon dioxide (CO2). If every oxygen atom imparts one electron to the carbon molecule, there will be 6 electrons in carbon particle and 7 electrons in every oxygen atom. This doesn't give the carbon atom as a total octet.

Sometimes more than one set of electrons is shared between two atoms. In carbon dioxide, a second electron from every oxygen atom is likewise imparted with the central carbon atom, and the carbon particle imparts one more electron with every oxygen atom.

Two sets of electrons shared between two atoms make a double bond between the atoms. A few particles contain triple bonds, covalent bonds in which three sets of electrons are shared by two atoms.

Please explain the difference between reactants and products in a chemical reaction.

KonstantinChe [14]

Answer

A reactant is a substance that is present at the start of a chemical reaction. These are what breakdown to form products and its always to the right.

A product is a substance that is present at the end of a chemical reaction. These are what are formed after the reactants are broken down, the end result.

In a redox reaction, electrons are transferred from the substance being reduced to the oxidizing agent.

babymother [125]

Answer: The correct answer is from the substance being oxidized to the substance being reduced.

Explanation:

Redox reaction is defined as the reaction in which oxidation and reduction reaction occur simultaneously.

Oxidation reaction is defined as the reaction where an atom looses its electrons. The oxidation number of the atom gets increased during this reaction.

$X\rightarrow X^{n+}+ne^-$

Reducing agents are defined as the agents which reduces the other substance and itself gets oxidized. These agents undergoes reduction reactions.

Reduction reaction is defined as the chemical reaction where an atom gains electrons. The oxidation number of the atom gets reduced during this reaction.

$X^{n+}+ne^-\rightarrow X$

Oxidizing agents are defined as the agents which oxidize other substance and itself gets reduced. These agents undergoes reduction reactions.

Electrons are transferred from one atom to another in this type of reaction from the substance which is getting oxidized to the substance which is getting reduced.

It can also be said that, electrons are transferred from reducing agent to the oxidizing agent.

Hence, the correct answer is from the substance being oxidized to the substance being reduced.

Iron has a density of 7.86 g/cm3. Calculate the volume (in dL) of a piece of iron having a mass of 4.79 kg .

Kazeer [188]

M = 4.79 kg = 4790 g
d = 7.86 g/cm3
density = mass/volume
v = m/d
v = 4790/7.86
v = 609.4 cm3
1 cm3 = 10^-2 dL

v = 609.4 x 0.01 = 6.09 dL
