Timothy always liked playing catch with his dad. Whenever he had the chance to pick up a small object, he simultaneously threw a random object at his dad to catch him of guard. His objective was to have his dad drop the item. One day, Timothy threw two objects at is dad. One object was a tennis ball and the other was a golf ball. His dad ended up dropping both of the objects on the floor but was able to catch them after the drop because they both bounced back into his father’s hands. He wondered how this was possible This led to Timothy asking a science question that he would like to test by doing an experiment. What science question do you think Timothy asked to jumpstart an investigation? THIS IS SCIENCE BTW BUT PLEASE HELP I WILL GIVE BRAINLIEST TO THE MOST ACCURATE AMSWER

Explain which group an element with the electron configuration 1s2 2s2 2p6 3s2 3p6 3d1 4s2 belongs to.

Salicylic acid is a very important acid. it is used to synthesize the aspirin by treating with acetic anhydride. a 0.2015-g sample of salicylic acid was dissolved in a 100.00-ml volumetric flask, and the solution was diluted to the mark. a 10-ml aliquot of this solution was titrated with standard naoh (0.01130 + 0.2% n) to a phenolphthalein faint pink color end point at 19.81 ml. (a) (calculate the normality of the salicylic acid solution used in the titration. (b) assuming the salicylic acid is pure, what is the equivalent weight of the salicylic acid? practice problems for the final exam (continued) (c) (calculate the inherent error in the determination of the equivalent weight you calculated in part (b). use the following absolute errors in the equipment /glassware when calculating the inherent error. 5.00-ml pipet: + 0.02 ml 100-ml volumetric flask: + 0.08 ml analytical balance: + 0.2 mg 25-ml buret: + 0.03 ml
