Write the net ionic equation for the precipitation reaction that occurs when aqueous solutions of ammonium phosphate and nickel(II) bromide are combined. Use the pull-down boxes to specify states such as (aq) or (s). If a box is not needed leave it blank.

Using data from seismic waves, geologists have learned that earth’s interior is made up of several

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.)

Glucose (c6h12o6) is an important biological molecule. (round the answer to nearest hundredth.) what is the percent by mass of carbon in glucose?
