Ethene (H2C=CH2) is a gaseous by-product of the long-chain hydrocarbons that are cracked to create highly sought-after goods like gasoline and aviation fuels.

<h3>What is ethene used for?</h3>
  • The uses of ethene include: It is employed in the creation of polythene. It is used to make fruits artificially ripe.
  • Ethene is also utilised to create other beneficial molecules such ethanol, oxyethylene flame, and ethylene glycol, which is used as an antifreeze.
<h3>Does ethylene resemble ethene?</h3>
  • A substance having the chemical formula C2H4 is ethylene, commonly known as ethene.
  • It is both the most easily manufactured organic compound in the world and the simplest alkene.
  • Unsaturated hydrocarbon ethylene, often known as C2H4, is utilised in industrial facilities and is occasionally found in typical medicine cabinets as a hormone.

3. The number of electrons and neutrons in an atom are 13 and 14, respectively. Find out the mass number, atomic number, valency
QveST [7]

Answer:

Explanation:

3. The number of electrons and neutrons in an atom are 13 and 14, respectively. Find out the mass number, atomic number, valency, and symbol of the element.

For a neutral atom. number of protons =number of electrons=13

so since atomic number is the number of protons =13

mass number = protons + neutons =14+13 = 27

atomic number 13 is Aluminum (AL-(see periodic table)

The electronic structure for 13 electrons is 1s2s2p63s23p1

so Al has 3 electrons which are VALIENT and can react and when it loses the 3 it will have  CHARGE OF +3

What does the group number of element 114 have to do with its stability?
zhenek [66]

Answer:

Super-heavy elements like 114 usually only exist for fractions of a second. ... The physicists called these magic numbers the “island of stability”, because the elements with the numbers cluster together on the periodic table, flanked on all sides by ephemeral elements that dissipate in nanoseconds.

I'd really appreciate help- this is due in around 8 hours :"D
Fed [463]

Answer:

  1. atomic #= 1
  • protons equals one
  • Number of neutrons equals to 0
  • number of electrons equal to 1
  • mass number equals to 1

2.

  • atomic number equals to 1
  • Protons equals to 1
  • number of neutrons equals to 0
  • number of electrons equals to 0 because the plus sign means that it loses an electron
  • mass number equals to 1

3.

  • atomic number 17
  • number of protons 17
  • number of neutrons 18
  • number for electrons 18 Because negative sign means It's an anion which means it gains an electron
  • mass number 35

4.

  • 12
  • 12
  • 12
  • 10 loses 2 its a cation
  • 24

5.

  • 47
  • 47
  • 108-47 = 61
  • 46 loses 1
  • 108

6.

  • 16
  • 16
  • 32-16 =16
  • 18 it gains 2 electrons
  • 32

there u go
