Please help , don’t answer if u don’t know please An experiment is...
Zn + 2 HCl = ZnCl2 + H2
a. Design an experiment that would produce curve Q on the graph below. (Hint: change the experimental parameters so that the rate of gas evolution changes according to the curves). You can also use the table to record your data.
b. What is the implication of the fact that the two curves touch? Explain.
c. Give a reason why the rate of hydrogen production slows down towards the end in both experiments.
I'm pretty sure about the answers. Hope you find this helpful
the five numbers are: 81, 88, 69, 65, 87. we know that to calculate the mean, you add all of the numbers together, and then divide by the number of numbers (hope that makes sense). So to calculate the mean of
81, 88, 69, 65, 87, we can add them all together first, and get 390. since there are 5 numbers we wish to calculate the mean of, we will divide 390 by 5 to get our answer, 78
thats how its supposed to be
