Recall all the models you described in task 1. Think about the results each model would predict for the experiment with hydrogen gas. Which models of the atom does the experimental evidence support?
Explain why these models are compatible with the experimental results.

Calculate the molarity of the solution. 6.02 x 1022 molecules of hci (molecular weight = 36.5 g/mole) in 2.0 liters of water m

Ahypothrticalax type of ceramic material is known to have a density of 2.10 g/cm3 and a unit cell of cubic symmetry with a cell edge length of 0.57 nm. the atomic weights of the a and x elements are 28.5and 30.0 g/mol, respectively. on the basis of this information, which of the following crystal structures is (are) possible for this material: sodium chloride, cesium chloride, or zinc blende

Match the mixture with the substance// i really need on this guys (it’s a pic btw)
