2c2h6 + 7o2 = 4co2 + 6h2o
what mass of co2 will be produced from the reaction of 37.5 g c2h6

use n=m/M (moles=mass/molar mass) to find out how many moles of C2H6 there are in 60g

Explanation:

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²

orbital diagram of c is as shown here in the image.

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error
