Answer:

Described by a redox reaction below

Explanation:

Iron(III) oxide is an ionic compound, since it consists of a metal, iron, and a nonmetal, oxygen.

Ionic compounds are formed when metals lose their valence electrons in order to have an octet in their previous shell and donate them to nonmetal atoms, so that nonmetals fill their outer shell to have an octet.

As a result, positive ions (cations) and negative ions (anions) are formed. When iron reacts with oxygen, the following reaction takes place:

$4 Fe (s) + 3 O_2 (g)\rightarrow 2 Fe_2O_3 (s)$

This is a redox (oxidation–reduction) reaction, since we have electron loss and gain. Four iron atoms lose a total of 12 electrons to obtain a +3 charge in the final compound, while 3 oxygen molecules gain these 12 electrons to become 6 oxide anions with a -2 charge.

A solution has a volume of 375 ml and contains 12.6 moles of NaCI what is it molarity

miskamm [114]

Answer:

M = 33.6M .

Explanation:

Hello there!

In this case, according to the definition of molarity which is computed by dividing the moles of solute by the liters of solution, it is possible to realize that the moles of the solute are 12.6 mol and the liters of solution are 375/1000= 0.375 L and therefore the molarity of the solution can be calculated as follows:

$M=\frac{12.6mol}{0.375L}\\\\M=33.6M$

Which has molar units, M.

when a compound containing c h and o is completely combusted in air what reactant besides the hydrocarbon is involved in the rea

Arada [10]

When a compound containing C, H and O is completely combusted in air what reactant besides the hydrocarbon is involved in the reaction is Oxygen.

<h3>What is hydrocarbon?</h3>

A hydrocarbon is an organic molecule composed completely of hydrogen and carbon in organic chemistry. Group 14 hydrides include hydrocarbons. Hydrocarbons are often colourless and hydrophobic, with scents that are weak or exemplified by gasoline and lighter fluid. They exist in a wide range of molecular forms and phases, including gases (like methane and propane), liquids (like hexane and benzene), low melting solids (like paraffin wax and naphthalene), and polymers (such as polyethylene and polystyrene). Hydrocarbon refers to naturally occurring petroleum, natural gas, and coal, as well as their hydrocarbon derivatives and refined forms, in the fossil fuel industry. The primary source of energy on the planet is the combustion of hydrocarbons.

Which statement describes both homogeneous mixtures and heterogeneous mixtures?

Elina [12.6K]

The given question is incomplete, the complete question is:

Which statement describes both homogeneous mixtures and heterogeneous mixtures?

Their components can be distinguished visually.

Their components are combined in a fixed ratio.

Their components can be separated by physical processes.

They always contain a liquid component.

They are considered to be pure substances.

Answer:

The correct answer is option C, that is, their components can be separated by physical processes.

Explanation:

A combination of two or more substances in which no reaction or chemical combination takes place is termed as a mixture. On the other hand, the atoms of different elements that are combined chemically in a fixed ratio are termed as a compound.

The mixtures, that is, whether homogenous or heterogeneous exhibits the tendency to get differentiated physically, on the other hand, compounds do not possess such a tendency. Like one can separate the mixture of alcohol and water by the process of distillation, as both the components exhibit distinct boiling points, that is, can be separated based on their physical characteristics.

On the other hand, if one desires to distinguish oxygen and hydrogen from water, then there is a need to dissociate the bonds present between the molecules of hydrogen and oxygen, which is its chemical property, not physical characteristics.
