As the shopping trip progressed, the cart increased in mass from 0 kg to 10 kg. Which argument below supports Raymond's claim that it was more difficult to push the 10 kg cart as opposed to the empty cart. O As the cart decreased in mass, Raymond had to use more force to push the cart. O As the cart increased in mass, Raymond had to use more force to push the cart. O As Raymond continued to push the cart during the duration of the trip, he became tired which made it more difficult to push the cart. O As Raymond continued to push the cart during the duration of the trip, friction began to build up on the wheels causing the cart to be more difficult to push.

After creating her standard curve for absorption versus the concentration (M) of FD&C Red 40 and processing her data, Sally found that her drinking strength Kool-Aid sample had a concentration of 4.692 x 10–5 M. If 0.132 grams of Kool-Aid powder was used to prepare an 8-fl oz cup of her assigned flavor, what is the percent by mass of FD&C Red 40 in her Kool-aid powder? Report your answer as a percentage with two places after the decimal. Do not include the percentage sign in your answer. Pay attention to units. You are trying to find the mass percentage of red dye, so you need to know each variable in the equation in Appendix B. Note that the percent by mass equation should be multiplied by 100. There may be some useful conversion factors in the experimental procedure.

PROVISIONAL LEWIS STRUCTURES T01/S01 For each provisional structure, identify if it is the correct Lewis structure (C) or if it needs to be modified according to procedure MA or MB to obtain the correct Lewis structure. MA. Form multiple bonds to the central atom using lone pair on the terminal atom(s) until the central atom has an octet (or septet). MB. Form multiple bonds to the central atom using lone pair on the terminal atom(s) until the central atom has a formal charge of zero (0) or until two double bonds are formed. A provisional structure has the valence electrons distributed in order as (1) a bond between each pair of atoms, (2) an octet for each ligand (terminal) atom or ligand group (CH3, NH2 or OH) and (3) any remaining electrons on the central atom.
A trainee in a medical lab will be released to work on her own when her results agree with the accepted value of 13.95 mg/dL at a 95% confidence level. Results of a blood urea nitrogen analysis are shown below. Trainee: x= 14.57 mg/dL s= 0.45 mg/dL n= 6 samples Should the trainee be released to work alone? Explain your answer.

After creating her standard curve for absorption versus the concentration (M) of FD&C Red 40 and processing her data, Sally found that her drinking strength Kool-Aid sample had an FD&C Red 40 concentration of 1.086 x 10–5 M. If 0.133 grams of Kool-Aid powder was used to prepare an 8-fl oz cup of her assigned flavor, what is the percent by mass of FD&C Red 40 in her Kool-aid powder?
