How many electrons are in octane?
66. Octane is C8H18. therefore the total number of electrons is 6*8 + 18*1
What is the ratio of carbon atoms to hydrogen atoms in a molecule of octane?
8 is not the answer because octane does no refer to the number of hydrogens but rather the number of carbons. c-c-c-c-c-c-c-c as you can see the number of hydrogens that would bond to the carbons is 18.-------The chemical formula of octane is C8H18, consequently the number of carbon atoms is 8.
What molecule is shown below C8H18?
The molecule shown is octane. It is a straight-chain alkane with 8 carbon atoms and 18 hydrogen atoms. Octane is commonly found in gasoline and is used as a fuel for vehicles.
What is the whole number coefficient of O2 when the equation for the combustion of C8H18 is completed and balanced?
The combustion reaction of octane is:2 C8H18 + 25 O2 = 16 CO2 + 18 H2OSo, the number of oxygen molecules is 25.The isomer trimethylpentane is used as standard in octane rating: the end of the scale at 100.
Is octane an ionic compound?
No, octane is not an ionic compound. Octane is a hydrocarbon, specifically an alkane, which consists of carbon and hydrogen atoms bonded together through covalent bonds. Ionic compounds are formed by the transfer of electrons between a metal and a nonmetal.
How many electrons are in octane?
66. Octane is C8H18. therefore the total number of electrons is 6*8 + 18*1

What weight of water is produced burning 19.8grams of octane?
The formula for normal octane is C8H18. Its molar mass is 114.23 g mol−1 The formula for its combustion is 2C8H18 + 25O2 --> 16CO2 + 18H2O So 1 mole of octane gives 9 moles of water. One mole of water has a mass of 18 g 19.8 g of octane is 114.23/19.8 moles so its combustions gives ((114.23/19.8) x 9 x 18 ) = 934.61 g of water
What is a use for octane?
Octane is one of the alkane group of hydrocarbons and is a major component of petrol (gasoline). Burning octane gives this chemical reaction: 2.C8H18 + 25.O2 = 16.CO2 + 18.H2O The formula shows that 1 kg of octane burns with 3.51 kg oxygen to produce 3.09 kg carbon dioxide and 1.42 kg water.
What is the chemical name for C6H8?
To my knowledge that chemical does not exist. An 8 carbon chain is fully saturated with 18 hydrogens: (CH3)(CH2)6(CH3) This adds up to 18 hydrogens and 8 carbons. This molecule is called octane. Hope that helps.
What molecule is shown below C8H18?
The molecule shown is octane. It is a straight-chain alkane with 8 carbon atoms and 18 hydrogen atoms. Octane is commonly found in gasoline and is used as a fuel for vehicles.
How many moles of H2O are produced when 0.468 mol of octane is burned?
First write down the BALANCED reaction eq'n. Octane + oxygen = Water + Carbon Dioxide. 2CH3(CH2)6CH3 + 25O2 = 18H2O + 16CO2 The molar ratios are 2:25 :: 18:16 So '2' moles of octane produces 18 moles of water. So by equivlance 0.468 : x :: 2 : 18 Algebraically rearrgange x = (0.468/2) X 18 => x = 0.234 x 18 = > x = 4.212 moles water produces.
What eliments are present in octane?
Since its chemical formula is C8H18, it contains 8 carbon atoms and 18 hydrogen atoms.
What is the boiling point of Gasoline 87 octane?
There are 18 different isomers of "octane", i.e. C8H18. Most likely the question refers to either the straight chain n-octane or to isooctane - the octane that the "octane" rating of gasoline is based on.For n-nctane:Boiling Point: 126C (259F)Melting Point: -57C (-71F)For isooctane (2,2,4 trimethylpentane):Melting point: -107 CBoiling point: 98 CIf you are looking for one of the other 16 isomers of octane, you need to specify which one.
What are the octane number of different hydrocarbons?
octane number of hydrocarbons like N-Nonane N decane cyclohexan heptane Neo Petane Mthyl hexane etc
What is tank capicity of lincoln ls 2005?
