A 4. 40-g piece of solid co2 (dry ice) is allowed to vaporize (change to co2(g)) in a balloon. The final volume of the balloon is 1. 00 l at 300. K. What is the pressure of the gas?.

While the change in blank will remain the same during a collision, the force needed to bring an object to a stop can be blank if the time if collision is blank

Which component of the earth’s atmosphere is decreased due to photosynthesis?

An electron is trapped at a defect in a crystal. the defect may be modeled as a one-dimensional, rigid-walled box of width 1.00 nm. (a) sketch the wavefunctions and probability densities for the n 1 and n 2 states. (b) for the n 1 state, nd the probability of nding the electron between x1 0.15 nm and x2 0.35 nm, where x 0 is the left side of the box. (c) repeat (b) for the n 2 state. (d) calculate the energies in electron volts of the n 1 and n 2 states
