5. A student attempts to write the balanced chemical equation for the decomposition of carbonic acid forming water and carbon dioxide.
H2CO3 - H2O-CO
Which statement describes what is incorrect about this chemical equation?
A. A plus sign (+) should replace the minus sign (-) in between the products.
B. There are an unequal number of oxygen atoms on both sides in the equation
C. The reactant and the products should be switched so they are on opposite sides of the arrow.
D. The CO2 should be on the left side of the equation following the other reactant & a minus sign (-).

The table compares the number of electrons in two unknown neutral atoms. comparison of electrons atom number of electrons a 9 d 11 use this information to determine the number of valence electrons in the atoms. which of the following correctly compares the stability of tthe table compares the number of electrons in two unknown neutral atoms. comparison of electrons atom number of electrons a 9 d 11 use this information to determine the number of valence electrons in the atoms. which of the following correctly compares the stability of the two atoms? both are unreactive. both are highly reactive. a is unreactive and d is reactive. a is reactive and d is unreactive.
