What makes a question scientific is that we are able to test our hypothesis.

For example:  Will increased sunlight cause more seeds to grow.  We can test that simply by placing seeds in the sun and some out of the sun.

If you cannot test an hypothesis, then it is NOT scientific

For example: Macroevolution isn't a scientific question because we cannot test whether or not complex organisms come from simpler organisms.  It can only be classified as an Hypothesis at best.

pishuonlain [190]

Answer:

Therefore 373 mole of Al produce 746 mole of water.

Explanation:

Given reaction is

3 Al+3NH₄ClO₄→Al₂O₃+AlCl₃+3NO+6H₂O

From the above reaction it is clear that 3 mole of Al produce 6 mole of water.

Therefore

3 mole of Al produce 6 mole of water.

1 mole of Al produce \frac{6}{3} mole of water.

373 mole of Al produce \frac{6\times 373}{3} mole of water.

                                      = 746 mole of water.

Therefore 373 mole of Al produce 746 mole of water.
