The answer is alkene.
An alkane is a saturated hydrocarbon, thi is it has only single bonds.
Alkenes and alkynes are unsaturated: alkenes have double bonds and alkynes have triple bonds.
Subsituted hydrocarbon, is a hydrocarbon with one hydrogen substituted by another element or a group.
For example:
CH3 - CH - CH3

F
Answer:A
Explanation:
In a metallic bond, the actions are simply held together by mobile electrons which form an electron cloud. This electron cloud holds the cations together in the solid metallic substance.
Answer:
Explanation:
1) alkali metals and halogens as alkalis have 1 electron they need to get rid of in order to gain a full outer shell of electrons and the halogens have to gain 1 electron.
2) they have the same number of electrons on the outer shells
3)they usually have high melting points
4) low or no reactivity
5) group 7
Answer:
2.453.
Explanation:
<em>∵ pH = - log[H₃O⁺]
</em>
[H₃O⁺] = 0.00352 M.
<em>∴ pH = - log[H₃O⁺] </em>= - log(0.00352) = <em>2.453.</em>
