HELP ME PLEASE WILL GIVE MORE POINTS AND BRAINLIEST!! The specific heat of aluminum is 0.900 J/gºC. How much energy is needed to raise the temperature of a 20.0 g block of aluminum from 22.8°C to 94.6°C?

Which statement is usually true about the relationship between activation energy and reaction rates? low activation energy barriers result in low rates. high activation energy barriers result in low rates. low activation energy barriers result in no reaction. high activation energy barriers result in no reaction.

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.
