Guys I really need your help on this! It's timed!

Use examples from the article to explain one positive and one negative effect that chemistry has had on society.

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.

Anyone who's in connections academy chemistry b have the factors that affect the rate of a reaction portfolio already done?
