It would depend, because the independent variable is what you are measuring, the dependent variable is what you are changing, and the controlled variable is the things that stay the same. So it would all depend on the experiment.
Hope I helped!

Answer:
Sn^2+(aq)/Sn^3+(aq)//F2(g)/2F-(aq)
Explanation:
In writing the shorthand notation for an electrochemical cell, the oxidation half cell is shown on the left hand side and the reduction half cell is shown on the right hand side. The oxidation half equation reflects electron loss while the reduction half equation reflects electron gain.
It describes the size of the orbital!! At least this is what I think your talking about!
Answer:
Explanation:
The percent yield is the ratio of the actual yield to the theoretical yield.
- The actual yield is the amount obtained from performing a chemical reaction. For this problem, it is 14.8 grams.
- The theoretical yield is the potential amount from performing a chemical reaction at maximum performance. For this problem, it is 23.5 grams.
We can substitute the known values into the formula.
Divide.
Multiply.
The original measurements for the theoretical and actual yields have 3 significant figures, so our answer must have the same. For the number we calculated, that is the tenths place.
The 7 to the right, in the hundredths place, tells us to round the 9 up to a 0. Since we rounded up to 0, we have to move to the next place to the left and round the 2 up to a 3.
The percent yield is approximately <u>63.0 percent.</u>
