For the reaction CH4(g) + 2H2S(g) ↔ CS2(g) + 4H2(g), after disrupting equilibrium the initial values for each gas were 1.24M CH4, 1.52M H2S, 0.285M CS2, and 0.233M H2. The original value for Kc was 0.00012, which means what about Q?

Which element is the least metallic between cadmium, silver, zinc, or iron?

How much heat is added if 0.814g of water increase in temperature by 0.351 degree c?

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.)
