Write and Balance the chemical equation and Identify the type of reaction. 8 marks Solid iron reacts with aqueous copper (I) nitrate to produce solid copper and aqueous iron (II) nitrate.     Aqueous potassium iodide reacts with chlorine gas to produce aqueous potassium chloride and iodine gas. Solid aluminum reacts with solid sulphur to produce solid aluminum sulphide. Solid potassium chlorate (KClO3) decomposes to form potassium chloride and oxygen gas.

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.)

8) warming your hands by a fire is an example if which heat transfer? a. conduction b. convection c. radiation d. none of these

Ascientist wants to know how individual lions within a pride interact with each other in their own environment. to do this, the scientist sedates and tags all of the lions within a pride. then, he places several remotely-controlled video cameras near the lions' den and performs an observational field study. he collects continuous video footage over the span of one year, analyzes the video, and then forms conclusions based on his observations.
