Imagine yourself making a nice cup of tea on a cold winter day. you begin by boiling some water in a kettle. next, you add the steaming liquid to your cup. then, you open a tea bag and repeatedly dunk it into the water. you pour a dash of milk and drop a few sugar cubes into the cup, stirring the solution with a spoon. finally, you squeeze a bit of lemon into your tea mixture. however, before you have time to stir the lemon juice into your tea, the liquid forms clumps. in other words, your tea has curdled!

name some of the chemical substances in the tea mixture.
which chemicals could have reacted to cause the curdling?

Which of the following statements about hybrid orbitals is or are true? choose all that apply. choose all that apply. under sp2 hybridization, the large lobes point to the vertices of an equilateral triangle. after an atom undergoes sp hybridization there is one unhybridized p orbital on the atom. the angle between the large lobes of sp3 hybrids is 109.5∘

Lab reagent, hypothesis test.a reference solution used as a lab reagent is purported to have a concentration of 5 mg/dl. six samples are taken from this solution and the following concentrations are recorded: (5.32, 4.88, 5.10, 4.73, 5.15, 4.75) mg/dl.these six measurements are assumed to be an srs of all possible measurements from solution.they are also assumed to have a standard deviation of 0.2, a normal distributin, and a mean concentration equal to the true concentration of the solution.carry out a significance test to determine whether these six measurements provide reliable evidence that the true concentration of the solution is actually not 5 mg/dl.
