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

According to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? view available hint(s) according to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? trigonal bipyramidal tetrahedral square planar determination of electron geometry requires information on whether the electron groups are lone pairs or bonding groups.
