PLS HELP ME PLS PLS I WILL MARK U AS BRAINLIEST Which statements accurately describe mass? Check all that apply.

Mass is a chemical property of an object.
Mass is measured using a balance.
The mass of an object remains constant.
Mass is the same as weight.
Kilograms are units of mass.

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
