Answer:
Mixtures
Explanation:
Matter can be classified as a compound and a mixture.
Answer:
C. Its oxidation number increases.
Explanation:
- <em><u>Oxidation is defined as the loss of electrons by an atom while reduction is the gain of electrons by an atom</u></em>.
- Atoms of elements have an oxidation number of Zero in their elemental state.
- When an atom looses electrons it undergoes oxidation and its oxidation number increases.
- For example, <em><u>an atom of sodium (Na) at its elemental state has an oxidation number of 0. When the sodium atom looses an electrons it becomes a cation, Na+, with an oxidation number of +1 , the loss of electron shows an increase in oxidation number from 0 to +1.</u></em>
The IUPAC naming of compounds follow a set of rules. First, find the longest carbon chain and number them. As shown in the picture, the longest chain has 9 carbons. In the 3rd and 5th carbon atoms, there is a double bond for each. So, the parent chain is named as 3,5 - nonadiene, 'di' because there are two double bonds. Moreover, at the 5th carbon, there is a branching chain of two carbons (ethyl). Hence, its IUPAC name is: <span>(3e,5z)-5-ethyl-3,5-nonadiene.</span>
Answer:
The ratio of aluminium and oxygen ions that only exists is 2:3
Since Aluminium has <u>3 valence electrons</u> and oxygen has <u>2 vacant orbitals</u>
Aluminium holds a valence of 3 and oxygen 2, when they react a compound of formula
is formed
