Calculate the mass in grams of Oxygen required to react completely with 0.75 moles of Aluminum. 4Al + 3O2→ 2Al2O3

a) 18 g of Oxygen
b) 9.0 g of Oxygen
c) 16 g of Oxygen

How would the number of moles (n) of o2 change if the atmospheric pressure doubled but all other variables stayed the same

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.

Which of these features are formed when hot groundwater is forced out through cracks in the earth's surface?
