if the rate of change in fossil fuel consumption by manufacturing from year 2 to year 3 continues, approximately how much fossil fuel will be consumed by manufacturing in Country X in year8 ?
The data provided as follows:
Year2:
Country X : 23
Country Y: 19
Year3:
Country X: 25
Country Y: 18
HELP PLZ !!!

from the graph constructed: calculate the rate of reaction at the 60th second and at the 180th second. write the formula and show work please. info: at the 60th second, it was 68.98 grams of caco3 in Hcl and at the 180th second, it was 68.63 grams.
