Calcium oxide and carbon dioxide combine to form calcium carbonate in the reversible reaction: CaO + CO2 ⇌ CaCO3

When the reaction is at dynamic equilibrium, which statement must be true?
Calcium carbonate and calcium oxide are formed at the same rate.

The forward and reverse reactions have stopped.

The concentration of calcium carbonate is increasing.

The reaction has run out of carbon dioxide or calcium oxide.

According to the diagram; a) identify the anode of the cell and write the half-reaction that occurs there b) write the overall equation for the reaction that occurs as the cell operates c) calculate the value of the standard cell potential ,e cell. d)write the shorthand notation of the cell above e)indicate the flow of the electrons on the diagram

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.
