Atank contains 1000 l of pure water. brine that contains 30 g of salt per liter of water is pumped into the tank at a rate of 25 l/min. the concentration of salt after t minutes (in grams per liter) is c(t) = 30t 40 + t . as t → ∞, what does the concentration approach?

Sorry i dont understand the question can you rephase it?

Ithe undersigned only for use your own email and delete any and copies and of the itself and to be there is a good timewhat does a decrease in temperature indicate about the molecules in a sample of liquid water? decreased chemical energy of the moleculesdecreased kinetic energy of the moleculesincreased chemical energy of the moleculesincreased kinetic energy of the moleculeshow does a sample of helium at 15 â°c compare to a sample of helium at 215 k? the helium at 15 â°c has a higher average kinetic energy than the sample at 215 k.the helium at 15 â°c has lower nuclear energy than the sample at 215 k.the helium at 15 â°c has slower-moving atoms than the sample at 215 k.the helium at 15 â°c has smaller atoms than the sample at 215 k.

The closer the atoms are to becoming ionic the more highly dense the negatively charged side gets.

C, small, hard spheres with insignificant volumes
