Tell me if these are right 24. earth's rigid out layer, consisting of the crust and uppermost mantle, is called the {" (Lithosphere) "} 25.

the pressure on 2.50L of N20 changes from 105 kPa to 40.5 kPa. if the temperature does not change, what will the new volume be.

What is Malleability

Propane can be turned into hydrogen by the two-step reforming process. In the first step, propane and water react to form carbon monoxide and hydrogen: C3H8 (g) + 3H2O (g) →3CO (g) + 7H2 (g) In the second step, carbon monoxide and water react to

Benzene, C6H8, has an enthalpy of fusion = 10.19 kJ/mol. Calculate the amount of energy which is needed to change 88.0 g of solid benzene at 5.53°C into liquid benzene, also at 5.53°C?
