3) Solid aluminum will react with concentrated hydrochloric acid to form hydrogen gas, according to the following equation: 2Al + 6 HCl > 2 AlCl3 + 3 H2

What mass of aluminum is required to produce 10 liters of hydrogen gas, measured at 35 C and .9855 atm?

How many moles of al3+ ions are in 1.25 moles of al2o3

Is this correct if not can u correct me

In a laboratory determination of the atomic weight of tin, a sample of tin is weighed in a crucible. nitric acid is added, and the reaction proceeds to give a hydrated tin(iv)oxide plus no2and h2o. the hydrated tin(iv)oxide is then heated strongly and reacts as follows: sno2.xh2o(s)sno2(s)+ xh2o(g)the sno2is finally cooled and weighed in the crucible. explain the effect on the calculated atomic weight of tin that would result from each of the following experimental errors: (a)considerable spattering occurs when the nitric acid is added to the tin.(b)the hydrated tin(iv)oxide is not heated sufficiently to change it completely to tin oxide.
