The first excited state of helium (he) is 159,850 cm-1 above the ground state. the first excited state of fluorine (f) is 404 cm-1 above the ground state. if we define the fraction of the atoms in the first excited state (fes) as latex: f_{\text{fes}}[\text{he or f}]f fes [ he or f ], which of the following statements is true at a temperature of 1000 k?

a) ƒfes [f] = 0
b) ƒfes [f] = 1
c) ƒfes [h] = 1
d) ƒfes [f] < ƒfes [h]
e) ƒfes [f] > ƒfes [h]

Aglow stick contains a glass vial with chemicals. when the glow stick is bent, the vial breaks and the chemicals react to produce a glow. a science student observes that a glow stick kept in the freezer glows for a longer duration than a glow stick kept at room temperature. what conclusion can be drawn based on the observation? be sure to note the outcome and test variables in the conclusion.

Someone offer some answers to this, i will give 98 coins and mark as brainliest! i will put the rest of the lab down in the comments,solutions pre-lab questions: in this lab, you will make fruit drinks with powdered drink mix. complete the pre-lab questions to get the values you need for your drink solutions. calculate the molar mass of powered fruit drink mix, made from sucrose (c12h22o11).using stoichiometry, determine the mass of powdered drink mix needed to make a 1.0 m solution of 100 ml. (hint: use molarity = to find the moles of drink mix, then convert moles to grams using a mole conversion.)what mass of powdered drink mix is needed to make a 0.5 m solution of 100 ml?
