If measurements of a gas are 75l and 300 kilopascals and then the gas is measured a second time and found to be 50l, describe what had to happen to the pressure (if temperature remained constant). include which law supports this observation.

When electrons are added to the outermost shell of a carbon atom, it forms--an anion that has a larger anion that has a smaller cation that has a larger cation that has a smaller radius.

A10-kg piece of aluminum sits at the bottom of a lake, right next to a 10-kg piece of lead, which is much denser than aluminum. which one has the greater buoyant force on it? explain. b - the aluminum a) both have the same buoyant force. b) the aluminum c) the lead d) it cannot be determined without knowing their volumes.

An electron in a television tube is accelerated uniformly from rest to a speed of 8.4\times 10^7~\text{m/s}8.4×10 7 m/s over a distance of 2.5 cm. what is the instantaneous power delivered to the electron at the instant that its displacement is 1.0 cm?
