A liquid-phase chemical reaction with stoichiometry A → B takes place in a semicontinuous reactor. The rate of consumption of A per unit volume of the reactor is given by the first-order rate expression rA(mol/liter·s) = kCA where CA(mol/liter) is the reactant concentration. The tank is initially empty. Beginning at a time t=0, a solution containing A at a concentration CA0(mol/liter) is fed to the tank at a steady rate Ф(liters/s). a. Write differential balances on the total volume of the tank contents, V, and on the moles of A in the tank, nA. Provide initial conditions for each equation. Your equations should contain only the variables nA, V, and t, and the constants Ф and CA0. Simplify the second equation to determine an expression for the steady-state value of nA. b. Integrate each equation to derive expressions for V(t) and nA(t). Use the latter solution to verify the expression for the steady-state value of nA derived in part a.

that's just how they are

explanation:

you can't control another persons decisions, all you can do is ask that they respect yours. relationships are hard because you have to put the effort into making sure that another person feels seen, heard, and loved. as time goes on, it gets easier, you learn how to do these things without thinking. loving them becomes as easy as breathing, but every relationship will have fights, and sometimes it'll feel like you're drowning, but as long as you can talk it out and compromise, because that's truly what loving another person is, is compromise, then you'll be okay. movies and tv shows have glamorized and romanticized (pardon the pun) what a relationship would be like. real relationships aren't perfectly timed kisses in the rain, zero fights until one big one ends everything, 6 month anniversaries. real relationships are sleepy confused kisses when one person has to leave for work earlier than the other,   real relationships are having small disagreements, real relationships are messy and confusing, real relationships is knowing that even if you're relationship may not last forever and this may not be the person you're going to spend the rest of your life with, that you love them, and you would do anything to see them happy. so yes, relationships are difficult, but so are many other things, relationships can be amazing but also stressful, and not just romantic i'm also talking about platonic relationships (although the primary example here was romantic) sometimes is best to leave friendships behind, so remember, always do whats going to you be happy in the long run.
