Critical Thinking Questions

1. Why do you think forensic scientists are so careful that the tests they do are sensitive, reproducible, and specific? What might happen if they were less careful about this?

They have to be careful to ensure as much accuracy as possible.

2.Which type of evidence do you think is most useful in an investigation? Why?

Physical evidence would probably be most important because it is the best way to connect someone directly with that crime.

3.Why do you think that forensic scientists continue to look for class characteristics given their limitations?

Class characteristics are good in court because it provides details of different aspects of the crime.

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !
