During a laboratory experiment 3.81g of NaHCO3 was thermally decomposed to generate 2.86 grams of carbonic acid (H2CO3). Calculate the percent yield of carbonic acid for the reaction. Show all work for the calculation (10 points). NaHCO3 → Na2CO3 + H2CO3

The table describes how some substances were formed substance 19 description formed by boiling pure water formed by combining three hydrogen atoms to every nitrogen atom formed by adding 5 g of sugar to 1 l of water formed by compressing carbon under high pressure based on the given descriptions, which substance is most likely a mixture?

If an area has high air pressure and low humidity, what type of weather will it most likely have? plz !

Consider this equilibrium: n29) + o2(g) + 2no(c).nitrogen gas and oxygen gas react when placed in a closed container. as the reaction proceeds towards equilibrium, what happens to the rate of thereverse reaction?
