Sodium nitrate can be heated in an environment with excess hydrogen to form
water. The two-step process is:
33
2 NaNO3 → 2 NaNO2 + O2
2 H2 + 02 → 2 H20
36
How many grams of sodium nitrate (NaNO3) are required to form 90.0 grams of
water?

How many mmols of tris-hcl are there in 100 ml of a 100 mm tris-hcl buffer solution at ph 8.1? note that the 100 mm refers to the sum of tris and tris-hcl concentrations?

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.
