The equation, as written is NOT balanced and does not follow the law of conservation of mass. The balanced equation is C2H8 + 4O2 ---> 2CO2 + 4H2O. This now follows the law of conservation of mass, because you have the same mass on both sides of the equation. Two Carbons on each side; 8 hydrogens on each side and 8 oxygens on each side.
The mass of the reactants is = to the mass of the products.
The equation is balanced, their is the same number of the same type of atoms on both sides.
All true but there is an impilicit assumption that the mass of a chemical compund is only due to its constituent atoms, and that mass is not affected by the nature of the bonding between the atoms. We know this istrue but that is based on a lot of experimental evidence that chemical change does not affect mass. In simple terms you should weigh the reactants and the products to prove the point and not make assumptions!
The compound C2H8 is commonly called Butene or butylene.
C3H8 + 5O2 ==> 3CO2 + 4H2O balanced equationmole ratio O2:C2H8 = 5:1 1.5 moles C3H8 x 5 moles O2/mole C3H8 = 7.5 moles O2 needed
Definitely ORGANIC. Organic chemistry is the study of organic compounds, that is the compounds containing Carbon. C3H8 contains three carbon atoms in the compound. From the formula it is probably propane (CH3-CH2-CH3) and organic hydrocarbon.
An empirical formula may or may not be the same as a molecular formula. The empirical formula of a compound shows the smallest whole-number ratio of the atoms compound. The molecular formula tells the actual number of each kind of atom present in a molecule of the compound.
The C2H4 molecule is nonpolar as a whole. The individual bonds in the molecule are moderately polar, but the molecule is symmetrical around its center line, and the polarities of the individual bonds cancel each other out at any visually perceptible distance away from the molecule.
the empirical formula of a compound tells you the proportions of the elements in the compound. with that information you can make some inferences about the identity of the compound. for example a compound with an empirical formula CH4 tells us that for every carbon atom there are four hydrogen atoms. this means that the compound is methane because no other hydrocarbon can have these roportions (try drawing the lewis structure for C2H8, which doesnt exist. you cant!)
To name any alkane, simply follow these 10 rules (go through them in order): 1) The following names are the basis of the system. The name depends on the number of carbon atoms: 1 carbon CH4: methane 2 carbons C2H6: ethane 3 carbons C3H8: propane 4 carbons C4H10: butane 5 carbons C5H12: pentane 6 carbons C6H14: hexane 7 carbons C7H16: heptane 8 carbons C8H18: octane 9 carbons C9H20: nonane 10 carbons C10H22: decane 2) For alkanes with branched carbon chains, determine which chain is the principal chain. The principal chain is the longest contiguous carbon chain. 3) If two or more chains in the structure have the same length, the principal chain is the one with the most branches. 4) Number the carbon atoms of the principal chain from one end to the other in the direction that gives the lowest number to the first branching point. 5) Name each branch and identify the carbon number on the principal where it is attached. For branch names, use the names from Part 1, but remove "ane" and add "yl" (e.g. methyl, ethyl, propyl, etc.) There are certain special groups with their own names, such as isopropyl, tert-butyl, and isobutyl (look these up for more information). 6) Construct the molecule name by adding the carbon number of the principal chain where it attached, then a hyphen, the name of the branch, and finally the name of the principal chain. That is: branching # hyphen branch name principal chain name Note that there are NO SPACES, such that the branch name and principal chain name form one word. 7) If the principal chain contains more than one branch, each branch receives its own number. Use the prefixes di, tri, tetra for 2,3, or 4 identical branches (respectively) 8) If substituent groups at more than one carbon of the principal chain, alternative number schemes are compared. The one that gives the lowest value is used. 9) Substituent groups are cited in the name in alphabetical order, regardless of their order of occurrence in the molecule. Prefixes di, tri, tetra, and tert are ignored, but prefixes iso, neo, and cyclo are not! 10) If number of different groups is not resolved by other rules, first cited group gets the lowest number. 11) if more than one same branches gets same no. from either side then number the chain such that the sum of the number of the branched carbon must be lower.
