Answer:
it gets reduced from a +3 oxidation to a 0.
Explanation:
the decomposition of iron oxide to elemenTal can be represented by the following equation: iron oxide (Fe203), the oxidation state of iron is +3 while that of oxygen is -2. therefore, the above reaction is a redox (reduction oxidation reaction)

Radiometric Dating. It's used to find the dates of ricks and other objects based on what the known decay rate of radioactive isotopes. Different forms of this method can also estimate the age of natural and man-made materials.
16 protons and 18 electrons gives the atom a -2 charge because there are 2 more electrons than protons. If it were 16 protons and 16 electrons, the charge would be 0 or neutral.
Answer:
Reactant : A combustion of hydrocarbon.
Explanation:
It is known that when hydrocarbons are involved in combustion, they produce carbon dioxide and water.
CxHy + (x+y/4)O2 ===> xCO2 + y/2H2O
Answer:
C) They all have single covalent bonds.
Explanation:
The given hydrocarbons Butane,Ethane,Methane,Propane belongs to alkane group.
In alkane group consists of hydrogen and carbon in which carbon_carbon bonds are single and carbon_hydrogen bond is also single.
The elements of this group makes bond by sharing of electrons that means they form single covalent bond.
Butane have 4 , Ethane has 2, Methane has 1, and Propane has 3 carbon atoms.
Since they have different number of carbon atoms so their structural formula also differs.
