the main componenet of egg sehell is the clacium carbonate CaCo3 . if you react egg sheels with acetic aci, d, from the vinegarthe following reaction wiil take place if 4.421 grams of carbon dioxide was produced from 10.57 g of egg. what percentage of the massof the egg shell has calcium carbonate

i think it is d. e because the next one is igneous.

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.

it is stable as it is in group 0 which have full outer shells of electrons

answer seismograph;
