A certain hydrocarbon, CxHy, is burned (reacts with O2gas) and produces 1.955 grams of CO2 for every 1.000 gram of H20. What is the empirical formula of this hydrocarbon?
CxHy + 02 --> CO2 + H2O*

Ithink is a because if say increased in electronegativity

Answerδh > 0explanationc₆h₆  (s)  → c₆h₆ (l)if you are changing it from a solid to a liquid, you are pretty much melting the solid. this requires heat energy. therefore, the reaction is endothermic (takes in energy); the system enthalpy increases as the reaction proceeds: δh > 0.

Ibelieve the answer 4 moles

Those are different gas lawshere is a brief description of themcharles's law states that volume and temperature are directly proportional to each other as long as pressure is held constant.  boyle's law asserts that pressure and volume are inversely proportional to each other at fixed temperature.gay-lussac's law introduces a direct proportionality between temperature and pressure as long as it is at a constant volume.    source:
