Which one reacts more rapidly with sodium ethoxide - ethanol crotylbromide or vinyl bromide?

Yes that is correct. However the reaction only goes to about 20% completion and is not very stable because of the presence water. The reaction is a follows: R-OH + NaOH <-> R-ONa + H-OH , where R is ethanol. The more common method used is: R-OH + M -> R-OM + 1/2H2(g), where M is a metal, like Na or K, etc

Is The colorless liquid ethanol burns in air a physical or chemical property?
ethanol is a type of alcohol, in the oxygenated hydrocarbon class of compounds. when it combines rapidly with oxygen in a combustion reaction, the ethanol is used up, and with oxygen forms carbon dioxide and water. ethanol is quite literally gone, it is broken down and reformed into new products, which is the definition of a chemical reaction.
Fact about bromine?
Bromine is liquid at room temperature but evaporates very rapidly into a purple-brown, choking gas that smells rather like chlorine. Sodium bromide, the bromine analog of table salt, is often used in hot tubs.
What causes atmospheric air to be rapidly heated?
In the atmosphere, warm surfaces can heat the air above them. High pressure in the atmosphere is what causes the air to rapidly heat.
What part of a rock does weathing attack most rapidly?
Weathering attacks the surface of the rock most rapidly.
Does soil rapidly cool at night?
yes
Solubility of azithromycin?
rapidly soluble in methanol , Acetonitrile and partially soluble water .

Where you get bromine from?
Bromine is prepared by a method which comprises contacting hydrogen peroxide with an aqueous solution containing bromide ion and rapidly removing the bromine as it is formed. This method is particularly suitable for obtaining bromine from seawater, using the conventional intermediate, bromosulfuric solution.
Do achohol make crackle nail polish?
Yes, ethanol is added to allow the polish to dry so rapidly it produces an appearance of a shattered surface. It is also formulated so the polish dries unevenly to produce the cracked effect.
How do ethanol burn?
Ethanol is an alcohol which reacts with oxygen to form water and carbon dioxide: C2H5OH + 3O2 = 3H20 + 2CO2 Exothermic, so heat is generated. The reaction is initiated by heat such as match or a spark (but see below about explosive limits). The flash point of ethanol is 9C, so if liquid ethanol is heated to that temperature a spark will ignite it in the presence of oxygen. At 8C, ethanol will not ignite unless the match heats it up by at least one degree. However, there are certain stipulations, known as the Explosive Limits The Lower Explosive Limit of Ethanol is 3.5% v/v, meaning that there must be at least 3.5% by volume of ethanol vapor in air for it to ignite, and: The Upper Explosive Limit of Ethanol is 19% v/v. If the volume of ethanol vapor in air is above 19% then it cannot ignite due to there being insufficient oxygen for it to ignite. If you rapidly immersed a lighted match into pure liquid ethanol it would extinguish the match due to a lack of oxygen in the liquid. An addition I forgot to mention: If you look ate the chemical equation, the atomic weight of hydrogen is 1, of carbon is 12 and of oxygen is 16 So a mole of ethanol will weigh 46g and a mole of 3 oxygen molecules is 96. So you need over twice the weight of oxygen as ethanol for it to burn. If we take the respective volumes of the two molecules at average room temperature, the Upper Explosive Limit is based on the fact that you cannot have that required ratio of oxygen to ethanol if the amount of oxygen present by volume to ethanol is only 81% It must be higher for the reaction to proceed.
