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.
What is the reaction between silver bromide and ammonia?
2 AgBr (s) + 2 NH4OH (aq) --> Ag2O (s) + H2O (l) +2 NH4Br (aq) The reaction does not proceed rapidly as in the case of AgCl as AgBr is only slightly soluble in ammonium hydroxide. With more NH4OH, the brown/black Ag2O dissolves forming the soluble salt Silver Di-amine hydroxide: Ag2O (s) + 4 NH4OH --> 2 [Ag(NH3)2]OH + 3 H2O I suspect that this reaction is reversible and the loss of NH3 would push the reaction to the left, which may occur naturally with time. This is a major problem as the precipitated Ag2O can further react with NH4OH to form Silver nitride, Ag3N: 2 NH4OH (aq) + 3 Ag2O (s) --> 2 Ag3N (s) + 5 H2O Silver nitride can be a highly sensitive and powerful contact explosive, even when in solution. This has been ascribed to be the cause of many injuries, and as such, solutions of [Ag(NH3)2]OH should not be stored for safety concerns.
What weather change is most likely indicated by rapidly falling air pressure?
A rapidly falling air pressure is often associated with the approach of a storm or low-pressure system, which can bring changes in weather such as strong winds, heavy rain or snow, and rapidly dropping temperatures.
What causes atmospheric air to be rapidly heated?
Atmospheric air can be rapidly heated by factors such as strong sunlight, combustion reactions from wildfires or industrial processes, or localized temperature inversions where hot air is trapped near the Earth's surface. This leads to an increase in temperature and can result in the formation of heatwaves or other extreme weather phenomena.
What part of a rock does weathing attack most rapidly?
Weathering typically attacks the outer surface or exposed edges of a rock most rapidly. This is because these areas are more exposed to the elements, such as rain, wind, and temperature fluctuations, which accelerate the breakdown of the rock material.
How bromine react with hydrogen?
Bromine reacts with hydrogen to form hydrogen bromide (HBr). The reaction is exothermic and proceeds rapidly to give a colorless gas. The reaction can be represented as follows: Br2 + H2 -> 2HBr.
Solubility of azithromycin?
Azithromycin is generally soluble in organic solvents like ethanol and methanol, as well as in aqueous solutions at a pH range of 9-10. Its solubility can vary depending on the specific salt form or formulation of the drug.

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.
What are the penetrating solute?
Penetrating solutes are molecules that can cross a membrane barrier easily due to their chemical properties, such as size and lipophilicity. Examples include urea, ethanol, and acetone. These solutes can equilibrate across cell membranes rapidly, impacting cell function and osmotic balance.
What is the synonym of rapidly?
rapidly
What is the comparative and superlative to the word rapidly?
more rapidly and most rapidly
What are the comparative and superlative form of the word rapidly?
more rapidly, most rapidly
Is it rapidly or more rapidly?
"More rapidly" indicates a greater degree of speed compared to "rapidly." Use "more rapidly" when describing an action that is quicker or accelerating at a faster pace.
What is comparative for rapidly?
more rapidly
