How is matter conserved in the carbon cycle?
a. carbon absorbs energy and later releases the same amount of energy.
b. carbon changes from one form to another, but the total amount of carbon remains the same.
c. people manage carbon resources, such as factory emissions, so they do not run out of carbon.
d. some forms of carbon, such as carbon dioxide stored in carbonate rocks, may remain in the same location for years.

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.
