The reaction below is at equilibrium. What would happen if more carbon were added?
C(s) +0,(9)
700 (9)
A. The equilibrium position would shift to produce more products.
B. The equilibrium position would shift to produce more oxygen.
C. The equilibrium position would shift to produce more reactants.
D. The equilibrium position would remain the same.

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

explanation:

originally atomic mass was used to arrange elements on the periodic table from left to right in a row. each column then shows similar properties of elements of a group.

in modern periodic table, the atoms are arranged in increasing atomic number. as atomic number represents the number of protons in an atom which is unique for every atom.
