Physics
how is does that work? isnt there some formula to figure out the mass gain?

Low Earth orbiting satellites orbit between 200 and 500 miles above Earth. In order to keep the satellites at a constant distance from Earth, they must maintain a speed of 17,000 miles per hour. Assume Earth's radius is 3960 miles. a. Find the angular velocity needed to ma...

For a double replacement reaction to occur, is it that one of the products must be insoluble and form a solid? There has to be some mechanism to remove the products from the reaction so that the reaction does not proceed in the reverse direction. Product needs to be removed: s...

In the equation: 2Al+6HCl-->2AlCl3+3H2 Why is the hydrogen by itself instead of the chlorine? Al is above hydrogen in the activity series (sometimes called the electromotive force series); therefore, it replaces H. This is single replacement type reaction. Isn't Al abov...
