How many carbon atoms does each of the following contain?   a) Ba(HCO3)2 b) CH3COOC2H5 c) (CH3)CH2CH(CH3)2

Professor Modyn studies combustion reactions in the laboratory. The professor would like to know the number of grams of carbon dioxide formed when 20.00 g of ethylene ( C2H4) is completely combusted with oxygen?

KCIO3 (s) - 2 KCI (s) + 02 (g) is 2 Combustion Reactions false True The total moles of 02 react with 6 moles of * ?C2H6 are 6 moles False True 2C2H6 + 702 4CO2 + 6H2O How many * ?moles of 02 react with 6 moles of C2H6 21 22 23 20

Fill the blanks to show the reaction(s) needed to make the molecule: OTS 1.03 2. H₂O OH NaC C-CH3 + CO2

how did we get the molecular mass all of these:  Methane CH4: 16.04 g/mol Ethene C2H4: 28.05 g/mol Isobutylene C4H8: 56.107 g/mol  Cyclooctane C8H16: 112.21 g/mol

1. Determine the empirical formula of a compound that is 15% C, 5.0% H, and 80% S in mass. molar mass: C: 12.01g/mol; H:1.008g/mol, S:32.07g/mol 2. Complete the combustion of 4.20g of hydrocarbon( contains only C and H) produced 12.9g of CO2 and 5.96g of H2O. What's the empirical formula for hydrocarbon? What's the molecular formula of hydrocarbon? The molar mass of the compound is 57g/mol.

organic chemistry- The double bonds in aromatic compounds do not undergo addition reactions. However, isolated double bonds undergo addition reactions. Br2  adds to double bonds and is yellow in color, If a Br2 solution in CCL4 is added to an akene the solution becomes clear, an indication that it added to the alkene. Can you use a Br2 to indicate that your product had an isolated double bond. If so, how much Br2 (Molar mass 158.8)  will you use. (this reaction is called Bromination)

An unidentified organic compound contains C, H and O atoms only. When 1.15 grams of this unknown organic compound was subjected to combustion analysis, it produced 2.20 grams of CO2 and 1.35 grams of H20. 1. Determine the empirical and molecular formulas of this organic compound (the molar mass is 46.00 g/mol). 2. Draw the two possible isomers of this organic compound and name them. How can mass spectrometry be used to identify which isomer the unidentified organic compound is?
