Plan a method the students could use to test their hypothesis.
polet [3.4K]

Hypothesis testing is a formal procedure for investigating our ideas about the world using statistics. It is most often used by scientists to test specific predictions, called hypotheses, that arise from theories.

There are 5 main steps in hypothesis testing:

State your research hypothesis as a null and alternate hypothesis.

Collect data in a way designed to test the hypothesis.

Perform an appropriate statistical test.

Decide whether to reject or fail to reject your null hypothesis.

Present the findings in your results and discussion section.

Though the specific details might vary, the procedure you will use when testing a hypothesis will always follow some version of these step

Given the two half-reactions, what must be done in the next step before the reaction can be balanced? Au3+ --> Au I- --> I
Artyom0805 [142]

Answer:

The balance equation is

2Au^{+3} + 6I^{-} → 2Au + 3I_{2}

Explanation:

first, we have to make sure that the atoms are balanced

Au^{+3} → Au^{}

2I^{-} → I_{2}

then we proceed to balance charges of each half-reaction

Au^{+3} + 3e^{-} → Au^{}

2I^{-} → I_{2} + 2e^{-}

Now we multiply the half-reactions to match the number of electrons in each one

(Au^{+3} + 3e^{-} → Au^{})x2

            (2I^{-} → I_{2} + 2e^{-})x3

and now we do the sum of the half-reactions

2Au^{+3} + 6e^{-} → 2Au^{}

              6I^{-} → 3I_{2} + 6e^{-}

2Au^{+3} + 6I^{-} → 2Au + 3I_{2}

note: the only atom that needed to be balanced was I
