Determine the molecular formula for this substance QUESTION 2 Classify the following reactions as synthesis (redox)'symthesis(non-rodox), decomposition(rodox), decomposition (non-redox), combustion, single replacement, doutole roplacement wi precipiation, double replacement w gas produced or double replacement wi acid buse. [Note. A synthesiz reacluon can also bes called a combination redction.
