Suppose that the two elements A (represented by triangles) and B (represented by squares) form a molecular compound with the molecular formula A2B, and that two other elements, C (represented by circles) and D (represented by diamonds), form an ionic compound with the formula CD. Draw a molecular-level view of each compound.

Astudent pours 10.0 g of salt into a container of water and observes the amount of time it takes for the salt to dissolve. she then repeats the process using the same amounts of salt and water but this time she slowly stirs the mixture while it is dissolving. the student performs the experiment one more time but this time she stirs the mixture rapidly. the dependent variable in this experiment is: time for salt to dissolve speed of stirring amount of water mass of salt
