Pleаse view the fоllоwing reаctiоns: C6H12O6 + O2 —> AlBr3 + Pb(NO3)2--> Li + H2O --> AlF3 --> HCl + Cа(OH)2 --> O2 + Ca —> You will complete the following for each reaction: (1 point) Identify what type of reaction (synthesis, decomposition, single replacement, double replacement, combustion) You will need to tell me which rule you used from the Chemistry Reference Sheet (alternate link if needed) to receive credit; For instance, for the example below, you should write synthesis (rule 1b). (2 points) Create the proper products You will also have to type in how you determined any ionic products. For instance, if Al(OH)3 is one of your products, you will need to indicate that Al has a 3+ charge, (OH) has a 1- charge, so the formula is Al(OH)3. If this explanation is not provided, you will not earn points for the creation of the proper products; (1 point) Balance the chemical reaction (with properly created products) (1 point) Please identify the precipitate for double replacement reactions. Identifying precipitates for other types of reactions would be incorrect. You will type in your answers, no attachments. The following formats will be accepted for your equation (you do not have to use subscripts if pressed for time): Al2O3 + 3 H2O---> 2 Al(OH)3 or Al2O3 + 3 H2O ---> 2 Al(OH)3
