What are 5 ways to identify the occurrence of a chemical reaction?

NaHCO3(s) + CH3COOH(aq) → CH3COONa(aq) + CO2(g) + H2O(l) \nThis is the real chemical reaction.

It can either be a strong acid, like HCl, or a strong base, like NaOH (aq.)  The reactions are:\n2Al + 6HCl => 2AlCl3 + 3H2\n2Al + 2NaOH + 2H2O =>2NaAlO2 + 3H2

1. Identify the problem. \n\n2. Refer to as many sources as possible.\n\n3. Ask an appropriate question. \n\n4. Develop a hypothesis.\n\n5. Do the experiment.\n\n6. Keep good records of the methods and results.\n\n7. Report the experiment.\n\n8. Analyze the results.\n\n9. Develop a conclusion.

!!!!!!!!!!!!!!!! \nI think rather u wanted to ask how can u predict the formula of a chemical reaction!!\nFirstly, we have to determine the moles of reactant taking part.(It can be done easily, think A reacts with B, just mix 1 mole of A with the same amount of B.)\nThen determine what are the different products and their amounts.\nAll u have to do is some calculations..................\nRemember its not as easy as it sounds.

1.  Heat speeds up a reaction by increasing vibrations and energy of the reactants.\n\n2.  Concentration speeds us a reaction by making more reactants available in a unit volume.\n\n3.  Catylists speed up a reaction (without being used up) by allowing reactants to come into closer proximity.\n\n4.  Increased surface area (by grinding, etc.) speeds up reactions by making more reactants exposed to reaction.

Take solutions of each metal ion and pieces of each metal.  Put metal pieces in each solution that does not contain that metal ion and observe whether any reaction is taking place.  Tabulate all observations and you should be able to see quickly which are the most and least reactive metals.

First make a chemical equation, balance it, and find a mole ratio.  Use that ratio and the above information to solve the problem.

There are a few methods, most of them require memorization, or a good chart.  For example, ionic compounds get named by adding the names of their ions, but molecular compounds get named by each individual element and a prefix of how many there are.  Then you have acids...  \n\nhere are some examples:\n\nNaCl - Sodium Chloride\nNa2CO3 - Soduum Carbonate\nNa3PO4 - Sodium Phosphate\n\nNotice that sodium is always sodium, not mono, di or tri.\n\nMolecular compounds are different, here are some examples:\n\nNF3- nitrogen trifluoride   \nNO - nitrogen monoxide OR nitric oxide (Ionic)\nNO2 - nitrogen dioxide  \nN2O - dinitrogen monoxide (laughing gas)\n\nI wont even go into acids, or Hydrocarbons\n\nI hope that gets you started anyway

Oxidation numbers: tell which atoms lose or gain electrons in chemical reactions, they can be determined by electronegativity\n\nThis web-site lays it out for you and gives examples.\n\nhttp://st19.startlogic.com/~honorsph/honorsphysicalscience/chemical%20formulas/writing_formulas.htm

There are various means of determining this, and without any specific data on what elements are involved in the answer you are looking for, the link below is the best reference I can find that can answer this question in a mostly generalized way.

the only way to determine the rate of a reaction is to do the experiment yourself.\n\nUse starch as the indicator and plenty of acid.
