Answer the questions in the table below about the shape of the iodite (10₂) anion. G 0 How many electron groups are around the central iodine atom? Note: one "electron group" means one lone pair, one single bond, one double bond, or one triple bond. What phrase best describes the arrangement of these electron groups around the central iodine atom? (You may need to use the scrollbar to see all the choices.) (choose one) X

It is showing how much energy it takes to remove an electron from each of those types of atoms. Why would 0.9 1-8 1-9 1-9 2-0 it be so high in the top right comer and so low in the lower len comer? It would be high in the top right coner because these electrons are closer to the nucleus and held more strongly, so they will take O A. more energy to remove. And the opposite is true for the lower left, farther from the nucleus and so not held as strongly, requiring less energy to…

Is the final answer correct ? Or would there only be two significant figures in the final answer ?

Please answers number 1-4 along with the with the correct solving of how you got the answers, I'm still confused on these.

How do I get the mass of Cu, g produced?

Many common materials that we ingest, though quite safe in reasonable quantities, become toxic when taken in very large doses. A measure of toxicity is the LD50 value (Lethal Dose, 50%). It is the quantity of material, expressed in mg of material per kg of subject-body-weight that, if administered to a population of subjects, would cause 50% of the population to die. The LD50 value for FD&C Red Dye No. 40 is >10,000 mg/kg in rats. Assume that the LD50 value for humans is the same as for rats. Calculate the number of mg of Allura Red present in an 8 fluid ounce glass of the beverage you used in this lab. Assume that the concentration of Allura Red in the beverage is 0.000054 M. The molar mass of Allura Red is 496.42 grams/mol 1 fl oz = 29.5735 mL Do not include units with your answer.

L, Of the container from part 'c'. ILS) A 0.50-kilogram serving of milk has an energy content of 371 kcal. A 0.50-kilogram uVing of ground beef has an energy content of 1470 kcal. A 60.00-kilogram man drinks 0.50 kilograms of milk in two minutes. At the same time, his 60.00-kilogram identical twin brother eats 0.50 kilograms of ground beef in two minutes. Immediately after the food is consumed, is one brother heavier than the other? If so, identify the heavier brother and explain why he is heavier. If not, explain why neither brother is heavier.
