When all the electrons are placed in their orbitals!!!
Answer:
-169°C to -104°C
Explanation:
Ethene, also known as ethylene exists in solid, liquid and gaseous states. Ethene is an aliens with condensed structural formula C2H4. Athens is a colourless gas. It is flammable and is also a sweet smelling gas in its pure form. It is the monomer in the production of polyethylene which is of great importance in the plastic industry. In agriculture, it is used to induce the ripening of fruits. It can be hydrated in order to produce ethanol.
The liquid range of ethene refers to the temperatures at which ethene is found in the liquid state of matter. It is actually the difference between the melting point and the boiling points of ethene. Hence the liquid range of ethene is -169°C to -104°C
Answer:
When hydrogen reacts with chlorine, hydrogen chloride is formed. Hydrogen chloride is a gas, and has the formula HCl(g).
When hydrogen chloride dissolves in water, hydrochloric acid is formed. This has the same formula, but you can tell the difference because of the state symbol (aq), which stands for ‘aqueous’. The formula is written as HCl(aq).
Hydrogen chloride is made from molecules. The hydrogen atom and the chlorine atom are joined by a covalent bond. When hydrogen chloride forms hydrochloric acid, the molecules split into ions.
HCl(aq) → H+(aq) + Cl-(aq)
The H+ ions make this aqueous solution acidic. The solution also conducts electricity because it contains ions that are free to move.
However, when hydrogen chloride gas dissolves in a solvent called methylbenzene, the molecules do not split up. A solution of HCl in methylbenzene does not contain hydrogen ions, so it is not acidic. The solution also has a low electrical conductivity.

Explanation:
<span>Heat released by the water: mass * specific heat * ΔT
Heat released by the water = 55.9 g * 1 cal / (°C g) * (99.2 - 96.9 )°C
Heat absorbed by the zinc metal = mass * specifi heat * ΔT
Heat absorbed by the zinc metal = 23.9 g * Cp * (96.9 - 21.1) °C
Heat absorbed by zinc metal = heat released by water
=> 23.9 * Cp * 75.8 = 55.9 * 1 * 2.3
=> Cp = 128.57 / 1811.62 = 0.0071 cal / (g°C)
Answer: 0.0071 cal / (g°C)
