A chemist needs to find out how large of a container would be required to contain the products of an ammonia decomposition. If 8. 91 mol H2 are produced during the reaction, how many moles of N2 are produced? 2. 97 mol N2 26. 7 mol N2 8. 91 mol N2.

Hey guys so i need to know what is _nh3+> nh4oh ~chemistry~

Which property of a rock remains unchanged by mechanical weathering? a. total surface area b. size and shape c. mineral composition d. sharpness

For a research project, a student decided to test the effect of the lead(ii) ion (pb2+) on the ability of salmon eggs to hatch. this ion was obtainable from the water‐soluble salt, lead(ii) nitrate, which the student decided to make by the following reaction. pbo(s) + 2 hno3(aq) → pb(no3)2(aq) + h2o losses of product for various reasons were expected, and a yield of 86.0% was expected. in order to have 5.00 g of product at this yield, how many grams of pbo should be reacted? (assume that sufficient nitric acid, hno3, would be used.)
