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.

Answer:
Model A
Explanation:
Model A represents an atom that is more reactive than the others represented.
Valence electrons actually determine the reactivity of elements. They also determine the properties of elements.
Elements with one valence electron are highly reactive because they need low energy to remove them. They can either gain more electrons to become stable or they share/give out their electrons.
Therefore, Model A is the correct answer because it has one valence electron and its valence electron is farther from the nucleus thereby this makes it more reactive.
Answer:
A. fluorine, 1.79 moles
Explanation:
Given parameters:
Mass of carbon = 87.7g
Mass of fluorine gas = 136g
Unknown:
The limiting reactant and the maximum amount of moles of carbon tetrafluoride that can be produced = ?
Solution:
Equation of the reaction:
C + 2F₂ → CF₄
let us find the number of the moles the given species;
Number of moles = 
C; molar mass = 12;
Number of moles = 
= 7.31moles
F; molar mass = 2(19) = 38g/mol
Number of moles = 
= 3.58moles
So;
From the give reaction:
1 mole of C requires 2 moles of F₂
7.31 moles of C will then require 2 x 7.31 moles of F₂ = 14.62moles
But we have 3.58 moles of the F₂;
Therefore, the reactant in short supply is F₂ and it is the limiting reactant;
So;
2 moles of F₂ will produce mole of CF₄
3.58 moles of F₂ will then produce 
= 1.79moles of CF₄
Answer:
Double Covalent
Explanation:
When two of the same element combine it will always be a covalent bond between them and since sulfur has two lone electrons it will make a double bond between the two to have a full octect
Answer: The excess amount changes from a gas into a liquid or solid (ice). The process of water changing from a gas to a liquid is called "condensation," and when gas changes directly into a solid, it is called "deposition." These two processes are how clouds form.
