A. gas change, color change, and temperature change.
B. color change; one day you wore a ring that wasn't stainless steel in the shower, so the following morning it was rusted.
For number 22. The answer is c. To find this look at the numbers before each compound O2 has no number which means 1, while CO2 has a 2 in front
We are given the number of moles:
O = 1.36 mol
H = 4.10 mol
C = 2.05 mol
To get the empirical formula, first divide everything by
the smallest number of moles = 1.36 mol. So that:
O = 1 mol
H = 3 mol
C = 1.5 mol
Next step is to multiply everything by a number such that
all will be a whole number. In this case, multiply by 2 to get a whole number
for C, so that:
O = 2 mol
H = 6 mol
C = 3 mol
Therefore the empirical formula of the compound is:
C3H6O2
