Answer:
A. CaCO(s)+SO(g)+O(g) --> CaSO(s)+CO(g)
A. CaCO(s)+SO(g)+O(g) --> CaSO(s)+CO(g)
Since there is 9.47 x 1021 atoms of copper in 1 gram, and 8.96 grams/cc is the density of copper, then 9.47 x 8.96 =84.85 x 1021 atoms of copper in the one cubic centimeter of copper.
The right answer is B.
In proposition B, 0.00116 meters is equal to 1.16 millimeters.
In Proposition A, it is equal to 11.6 millimeters (1km = 1,000,000mm), the decimal point is six digits.
In Proposition C, 0.116dm is equal to 11.6 millimeters (1dm = 100mm), the decimal point is shifted by two digits.
In proposition D, 1.16cm is equal to 11.6 millimeters (1cm = 10mm), the decimal point is shifted by one digit.
