"the combustion of ethylene proceeds by the reaction c2h4(g) + 3o2(g) → 2co2(g) + 2h2o(g) when the rate of disappearance of o2 is 0.23 m s-1, the rate of disappearance of c2h4 is m s-1."

Given the following reaction: c3h8+5o2=3co2+4h20 how many grams of co2 will be produced 7 g of c3h8 and 98 g of o2

Most materials are not magnetic because their magnetism has worn off. their magnetic domains are arranged randomly. they lack magnetic fields. earth’s heat has destroyed their magnetism.

How is energy related to the change of state represented by the model? atoms gain energy as a solid changes to a liquid. atoms gain energy as a solid changes to a gas. atoms lose energy as a solid changes to a liquid. atoms lose energy as a solid changes to a gas.
