“How else could you have tested the law of conservation of matter for this reaction? What other experimental designs could you have implemented? Write a different procedure that can be used to test
this law. Use a separate sheet of paper.”

The lab was to fill a flask with baking soda and vinegar, blowing a balloon up.

Answer(a) cheap enough for small shops to purchase;

Ibelieve it is d but i may be wrong

The answer is    (d) 7/2======we have    we also  have an integral      notice how function f splits up at x = 0. there's a left piece and a right pieceso we'll need to do the same thing with our integral: split it at x = 0we use a property of integrals that allows us to split up and sum:     notice that for the piecewise function f, the function has the equationf(x) = x when x  ≤ 0. so for the integral  , f(x) = x so it changes into      for the piecewise function f, the function has the equationf(x) = x+1  when x  > 0. for the integral  , we have    therefore, back to our splitted integral:    

Ithink the answer is d
