What is the shielding constant experienced by a valence p-electron in the bromine atom​

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.

How does the viscosity of magma change as magma cools?
