Which of the following is true about the differences between the "Plum Pudding" model and Rutherford's model? There are two possible answers. A. Both models describe food.

B. The plum pudding model had no deflection of particles because it lacked a nucleus

C. Rutherford's model showed deflection of particles because the nucleus has positive and neutral particles.

D. The plum pudding model and Rutherford's model are the same

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.)
