The reaction of Zinc (Zn) with hydrochloric acid (HCl) creates zinc chloride (ZnCl) solution and hydrogen gas (H2). If 2.56 grams of zinc reacts with excess HCl, what volume (in L) of hydrogen gas will be produced at 1.05 atm and 23oC? Zn + HCl -> ZnCl2 + H2

beta decay is the answer

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.

the correct answer is:

a. formation of precipitation

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
