What type of organic compound is represented by the formula CH3 CH2 4COOH?
It is scat. Look it up. It's the chemical formula for scat.
Is decompose into h2 and o2 a chemical or physical property?
If a molecule decomposes, then it is a chemical change. Like for water (H2O), It will look like this: 2 H2O -> 2H2 + O2 Since the actual original chemical changed, it is a chemical reaction.
When a wick is burned does a chemical change occur?
Yes, it is chemical: look at the remainings of the wick: black carbon-like, not white fiber anymore.
Why the reaction of ethanol acid with magnesium is slower than the reaction of hydrochloric acid with magnesium?
ethanol does not dissociate as much in solution as much as HCl , look up there pka values in future
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 is chemical warfare?
Its on mw3.The look like suicide bombers but with chemical gases the kill you slowly.
Does BP Amoco gasoline contain ethanol?
The only way to tell whether ethanol is present in gasoline is to look at the gasoline pump. If it contains ethanol, there should be a large sticker on it stating what percentage of ethanol is in the gasoline.
What is the chemical romance video where they look like JFK?
The Ghost of You.
What is the indcators of chemical change?
An indicator of chemical change is when he object doesn't look like its own or it change its principles like shape, taste and texture.
Where is a speed governor look like?
Lines of computer code. The speed governor is a programmed setting, not a physical component.

Why the formation of water in the car engine is a chemical change but when ice melts it is not a chemical change?
Ice melting would look like this in a chemical reaction equation: H2O+heat=H2O This is not a chemical reaction, but a thermal one. Water forming in a car engine would look more like this: 2H+O+heat=H2O This is a chemical reaction
What does the chemical FeO look like?
Iron(II) oxide (FeO) is black.
What does structural formulas look like?
The chemical formula of hydrogen sulphide is H2S.
What do you do when your hands look like they have chemical burn?
put hands on cold water
Does shell gasoline contain ethanol?
It depends sometimes it can sometimes it doesn't.Normally if you look at the sign that tells you the prices when your on the road it should say contains ethanol.
