Electrons striking the back of a TV screen travel at a speed of about 7.2 x 107 m/s. What is their de Broglie wavelength? M = 9.11 x 10-31 kg Characteristic X-rays emitted by molybdenum have a wavelength of .087 nm. What is the energy of one of these x-ray photons?

Fill in the coefficients that will balance the following reaction: a0cr2(so4)3 + a1agno3

Freezing and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.
