I’m stuck on a haber process calculation. the process requires large amounts of hydrogen gas and one source is hydrolysis of water. how many l of water would need to be hydrolysed to produce 46.30 grams of hydrogen?

For which one of the following reactions is the value of δh° rxn equal to δh° f for the product? a. 2 h2 (g) + o2 (g) → 2 h2o (l) b. n2 (g) + o2 (g) → 2 no (g) c. 2 h2 (g) + o2 (g) → 2 h2o (g) d. h2o (l) + 1/2 o2 (g) → h2o2 (l) e. none of the above

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.

Which suspect most likely committed the robbery and how do you know
