Does the model correctly represent the electron dot diagram of magnesium? why or why not? check all that apply.
m g with 1 dot above and 1 right.
yes, because the chemical symbol of magnesium is mg.
no, because the chemical symbol of magnesium is mn.
yes, because magnesium has two valence electrons.
no, because magnesium has seven valence electrons.
no, because both of the dots should be on top of the chemical symbol.

Alfred pushes on a heavy box, but cannot move it. the box has a lot of inertia motion friction gravity

The volume of a gas is halved during an adiabatic compression that increases the pressure by a factor of 2.5. what is the specific heat ratio? show the math steps .

Apositive charge moves in the direction of an electric field. which of the following statements are true? check all that apply. check all that apply. 1.the potential energy associated with the charge decreases. 2. the electric field does positive work on the charge. 3. the electric field does negative work on the charge. 4. the potential energy associated with the charge increases. 5. the electric field does not do any work on the charge. 6. the amount of work done on the charge cannot be determined without additional information.
