Solid sodium reacts violently with water, producing heat, hydrogen gas, and sodium hydroxide. How many g of hydrogen gas are formed when 125.0 g of sodium are added to water? 2Na + 2H2O → 2NaOH + H2

Which statement is actually 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.
