14/1/2009· When heated, calcium carbonate decomposes to form calcium oxide and carbon dioxide. Write the equation for this reaction. He never really mentioned how to write the heat part in the equation, so I kind of just winged it.
Writing and Balancing Chemical Equations · Chemistry
When balance is achieved, all the equation’s coefficients may then be multiplied by a whole nuer to convert the fractional coefficients to integers without upsetting the atom balance. For example, consider the reaction of ethane (C 2 H 6 ) with oxygen to yield H 2 O and CO 2 , represented by the unbalanced equation:
