CH4 + 3C12 > CHCl3 + 3HCI How many moles of HCl are formed if 4.5 moles of Cl2 and 8.00 moles of CH4 are given?

In the reaction between a crushed antacid tablet and vinegar what gas is emitted

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.)
