Steam at 100°c is condensed into a 38.0 g aluminum calorimeter cup containing 280 g of water at 25.0°c. determine the amount of steam (in g) needed for the system to reach a final temperature of 40.0°c. the specific heat of aluminum is 900 j/(kg · °c).

Which of these is not a possible type of energy transformation? a. electrical energy into light energy b. sound energy into nuclear energy c. potential energy into kinetic energy d. kinetic energy into mechanical energy

It is really hard for me right know

Click the game tab at the bottom of the simulation and select level 1. (there is no seesaw balance for this part of the activity.) balance the first equation, and click check to see if you got it right. if you can’t balance it in the first try, you can try again. work through the five equations for level 1. click continue to go on to level 2, and later level 3. each level is more difficult than the one before. keep trying until all the equations are balanced. in one or two sentences, describe how you did in the balancing game. in a few more sentences, explain one strategy you learned for balancing more complex equations.
