Step 1: 6 carbons on the left, so you need 6 CO2 on the right. Fire is set to it. Hexane is an alkane with the chemical formula C 6 H 14.As a hydrocarbon, it can undergo hydrocarbon combustion which gives off heat.Traces of hexane can be found in raw natural gas, which is a type of fossil fuel. The reactions that yield water, energy and carbon dioxide as products on reacting compounds with oxygen are termed as combustion reactions. The brown bromine water is decolourized and a colourless solution is formed. Cycloalkenes generally are more reactive than Cycloalkanes due to their double carbon-carbon bond. Note: Cheméo is only indexing the data, follow the source links to retrieve the latest data.
