Ethylene is a hydrocarbon which has the formula C ₂H ₄ or H₂C=CH₂. It is a colourless flammable gas with a faint "sweet and musky" odour when pure. It is the simplest alkene.
Ethylene is widely used in the chemical industry, and its worldwide production exceeds that of any other organic compound.
<h3>What is ethylene used for?</h3>
Medical: Ethylene is used as an anaesthetic. Metal Fabrication: Ethylene is used as oxy-fuel gas in metal cutting, welding and high velocity thermal spraying. Refining: Ethylene is used as refrigerant, especially in LNG liquefaction plants. Rubber & Plastics: Ethylene is used in the extraction of rubber.
<h3>Is ethylene harmful to humans?</h3>
* Ethylene gas can affect you when breathed in. * Skin contact with liquid Ethylene can cause frostbite. * Exposure to Ethylene can cause headache, dizziness, fatigue, lightheadedness, confusion and unconsciousness. * Ethylene is a HIGHLY FLAMMABLE and REACTIVE chemical and a DANGEROUS FIRE and EXPLOSION HAZARD.

KCl is neutral because KOH is a strong base and HCl is a strong acid
To determine if the salt is neutral, acidic or basic, determine how the salt was made, or from which acid and base it was derived. Once we have determined how the salt was made, determine if the acid and base are both strong, weak or one of each. If both are strong (e.g. NaOH + HCl), then the salt (NaCl) is NEUTRAL. If the base is strong and the acid is weak (KOH + HCN), then the salt (KCN) is BASIC. IF the base is weak and the acid is strong (NH3 + HCl), then the salt (NH4Cl) is ACIDIC. If both the base and the acid are weak (NH3 + CH3COOH), then then salt (CH3COONH4) will have a pH determined by which is stronger (the acid or the base) and this will depend on the Ka of the weak acid compared to the Kb of the weak base.
KCl is neutral because KOH is a strong base and HCl is a strong acid NaCN is generally basic because NaOH is a strong base and HCN is a very week acid. NH4NO3 is usually acid because HNO3 is a strong acid and NH4OH is a week base
CH3COONH4 is exactly neutral because both NH4OH ad CH3COOH are respectively week base and week acid. Moreover, the Ka of acetic acid is exactly equal to the Kb of NH4OH
To know about strong base.

In this case, for the given molarity and volume of such solution, the moles of sodium sulfate are computed below:
Now, by using the Avogadro's number, the ions result:
Best regards.
Answer: subduction and sea floor spreading
Explanation:
He knew that the continents today were once joined together by fossil records of plants and animals that were found to be on continents far removed from each other. He knew this also by corresponding land forms that matches up as well. What he couldn’t prove is how the land masses would have moved so far away from each other. Subduction and sea floor spreading move the tectonic plates that the continents sit on. That’s what he was missing.
In an ionic bond, electrons are transferred from one stone to another atom (shared).
