What does CXHY stand for?
Hydrocarbons are compounds consisting only of carbon or hydrogen.
What is the molecular formula of CXHY?
Hence , there will be 6 hydrogen atoms attached. Therefore , the molecular formula of the compound is C2H6.
What is hydrocarbon in chemistry?
A hydrocarbon is any of a class of organic chemicals made up of only the elements carbon (C) and hydrogen (H). The carbon atoms join together to form the framework of the compound, and the hydrogen atoms attach to them in many different configurations. chemical compound. Learn more about chemical compounds.
What is the chemical equation for burning wax?
Q: Write a general chemical equation for the reaction that occurs when a fuel such as candle wax burns. A: The burning of fuel is a combustion reaction. The general equation for this type of reaction is: Fuel + O2 → CO2 + H2O.
What is fuel chemical formula?
| Name | Molecular Formula |
|---|---|
| Gasoline is a mixture of many straight chain, branched, and aromatic hydrocarbon molecules in the range of C7 through C11 or 12. | |
| undecane | C11H24 |
| dodecane | C12H26 |
| Kerosene, jet fuel, and diesel fuel contain hydrocarbons in the range of C12 to C20. Fuel Oil has a range of hydrocarbons of C20 to C40. |
What is the chemical formula of hydrocarbon?
They are composed entirely of single bonds and are saturated with hydrogen. The formula for acyclic saturated hydrocarbons (i.e., alkanes) is CnH2n+2. The most general form of saturated hydrocarbons is CnH2n+2(1-r), where r is the number of rings. Those with exactly one ring are the cycloalkanes.
What is the empirical formula of CxHyOz?
C3H
If one molecule of the above compound (C/H,O,) contains half as much oxygen as required to burn one molecule of compound CxHy completely to CO2 and H,O. The empirical formula of compound CxHyOz is : (1) C3H.
What is true of all combustion reactions?
Combustion reactions always involve molecular oxygen O2. Anytime anything burns (in the usual sense), it is a combustion reaction. Combustion reactions are almost always exothermic (i.e., they give off heat). When organic molecules combust the reaction products are carbon dioxide and water (as well as heat).
What is hydrocarbon liquid?
What are hydrocarbon gas liquids? Hydrocarbons are molecules of carbon and hydrogen in various combinations. Hydrocarbon gas liquids (HGLs) are hydrocarbons that occur as gases at atmospheric pressure and as liquids under higher pressures. HGLs can also be liquefied by cooling.
What is hydrocarbon class 11?
Hydrocarbons are the organic compounds containing carbon and hydrogen only, e.g., alkane, alkene and alkynes. Classification of Hydrocarbons. Alkanes. Alkanes are saturated, open chain hydrocarbons containing carbon-carbon single bonds. e.g., methane (CH4), ethane (C4H6) propane (C3H8), etc.
What is the chemical symbol of candle?
In chemistry, paraffin is used synonymously with alkane, indicating hydrocarbons with the general formula CnH2n+2….Paraffin wax.
| Identifiers | |
|---|---|
| Chemical formula | CnH2n+2 |

What chemical is in candle wax?
paraffin wax
Answer 1: So many candles are made from “paraffin wax” which has the chemical formula C25H52. When paraffin comes into contact with oxygen with enough energy, it burns completely and becomes water and carbon dioxide. The fire is a result of this reaction happening very quickly and is known as combustion.
What are the chemical symbols for elements?
List of chemical symbols Chemical symbol Name of Element Atomic No Origin of Symbol Ac Actinium 89 Ag Silver 47 From the Latin Argentum which originally Al Aluminium 13 Am Americium 95
What is the name of the element with the symbol no?
Chemical symbol Name of Element Atomic No Np Neptunium 93 O Oxygen 8 Os Osmium 76 P Phosphorus 15
What does GHS stand for in chemical labeling?
As a result of updated OSHA chemical labeling requirements, 2016 marks the first full year of adoption of the Globally Harmonized System of Classification and Labeling of Chemicals (GHS) in the U.S.
What does the exclamation mark mean on a drug label?
Exclamation Mark: An immediate skin, eye or respiratory tract irritant, or narcotic.
