QUESTION 9 An energy bar contains approximately 16.7 grams of protein. Given that the energy content per gram of protein is approximately 4.0 Calories, that is the total energy content of the energy bar in joules? (1 calorie = 4.184 J) QUESTION 10 A 16.2 gram bar of iron initially at 72.5 "c, was added to 87.9 grams of water initially at 17.9 "C. Given that the specific heat of iron is 0.444 J/g'C and that of water is 4.184 J/g*C, what will be the final temperature of either of the two substances?

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.

4- Give any branch of chemistry that is widely studied? Chemistry is the study of matter - anything that has mass and volume. This central science looks into the physical and chemical properties of matter and how these properties are connected to the structure of matter in an atomic or molecular level. The changes involved in matter are also looked at be it physical change or chemical change.

Scientists can learn a great deal about a community's drug use (both legal and illegal) by analyzing the contaminants in wastewater. In a recent study in New York State, chemists measured the concentration of cotinine, a derivative of nicotine that i produced in the liver and excreted in the urine of tobacco users. The chemists found the average cotinine concentrations in the wastewater stream was 1.43 µg/L. a Ι Ι H- b HH H H-C C-N: C=0: TH HH Jonutis/Shutterstock Revell, Introductory Chemistry, 2e, © 2021 W.
