The addition of solute particles into a solution causes: A. the solute particles to bump the solvent particles out of the solution, making it easier to boil. B. the solvent particles to be spread further out and have more to move, increasing their kinetic energy. C. the solute particles to form seed crystals and make the solution freeze more easily. D. the solvent particles to be attracted to the solute particles and to have less kinetic energy.

the answer is alpha particles hope i you

u i forgot the answer?

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
