calculate the volume of hydrogen produced at s. t.p when 25g of zinc are added to excess dilute hydro chloric acid at 31 degree c and 778 mmHg pressure. H=1, Zn=65, Cl=35.5. Molar volume of gas at s. t.p=22.4dm3 no show all workings

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be

a saline water is fed to a reverse osmosis unit at flow rate o rotameter connected to reject (retentate) line reads 8 installed in reject and permeate line reads 15.2 milli siemens/cm and 300 micro siemens/com respectively.

girl imma just put my comment here because i need a couple point okurrttt
