is it possible to use the gas which is formed by citric acid and baking soda when mixed and water is added to change into electricity?

Re: science fair due in 3 months .
jessica007 - The gas resulting from the citric acid + baking soda reaction is non-combustible carbon dioxide. Using the gas directed through an appropriate nozzle to turn an impeller or vane, as in a wind turbine, would produce some electricity. You could use a DC motor as your generator. Much more complex (and expensive) would be to use a piston engine similar to a model steam engine to turn a shaft which in turn would drive the electric generator. In any case, a fairly large volume of gas would be required to sustain even a small amount of electricity generation.
