The atomic number of a neutral atom is equal to the number of protons and the number of electrons of the atom. The atomic weight meanwhile is equal to the sum of the number of protons and number of neutrons. Isotopes differ in the number of neutrons but the number of protons remain the same. In this case, the answer is B

1. Explain how volcanoes and earthquakes relate to each other.
zalisa [80]
1.Some earthquakes are associated with volcanoes. A lot of earthquakes are alongside the rims of tectonic plates. This is in which some volcanoes are too.
2. Earth changes in its personal ways. Some changes are because of gradual processes, consisting of erosion and weathering, and a few changes are because of fast processes, consisting of landslides, volcanic eruptions, Tsunamis and earthquakes. Waves, wind, water, and ice form and reshape the Earth's land surface through eroding rock in a few regions and depositing them in different regions, now and again in seasonal layers. Tectonic plates drift, the crust quakes, and volcanoes erupt. All of these effective forces form our air, land, water, and climate and are constantly reworking our planet.

According to the iupac convention, alkyl substituents on a hydrocarbon chain should be listed in which order?
Scilla [17]

According to the IUPAC convention alkyl substituents on a hydrocarbon chain should be listed in alphabetical without considering prefixes order.

<h3>What is IUPAC convention?</h3>

IUPAC convention of organic chemistry is a method of naming organic chemical compounds as recommended by the International Union of Pure and Applied Chemistry (IUPAC).

The name of the compound is written out with the substituents in alphabetical order followed by the base name (derived from the number of carbons in the parent chain).

Types of IUPAC  Nomenclature of a few important aliphatic compounds:

  1. Alkane
  2. Alkene
  3. Alkyne

Example :

Ethane, which has 2 carbon atoms and 6 hydrogen atoms, with the molecular formula of = C₂H₆

Formation of alkyl group:

Methane (CH₄)  Remove 1 hydrogen (H) convert to methyl (H₃-C-)

Example: Propyl (-CH₃ - CH₂ - CH₂ - )

According to the IUPAC convention alkyl substituents on a hydrocarbon chain should be listed in alphabetical without considering prefixes order.
