DUE IN 10 HELP John was asked to create a model that showed the difference between conductors and insulators. The model he created is shown below. Evaluate his models and his description of his model to determine if John shows the difference between a conductor and an insulator. Describe what is good and what might be improved in his model.

Plz choose one of the compounds from the table and explain how you know the numbers of atoms in your formula. is it possible for two different compounds to be made from the exact same two elements? why or why not? with a limited number of elements (less than 120 are known), does this mean we also have a small number of compounds or do we have a large number of compounds in this world?

If two atoms are bonded to a central atom with no lone pairs, how will they be arranged

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
