PRACTICE ANOTHER For the most common ion formed by each of the following atoms write the electron configuration (in noble gas notation), and predict the charge. (Hint: If more than one ion is likely, use the charge that is the least positive or most negative charge. For the "most common ion", type your answer using the format +1 and -2.) Atom Electron configuration of the most common ionCharge of the most common ion(a) S chemPad Help [Ne]3s2 3p6 Your answer does not contain the correct element for the noble gas base notation.
insects determine sex differently than either birds or mammals. If a grasshopper has the sex chromosome XXY, what sex will that grasshopper be and why?
In August 2018 and July 2019, the Secretary of Agriculture, Sonny Perdue, announced that the USDA would take several actions to support farmers in response to potential loss of profit from trade policies. First, the USDA’s Farm Service Agency (FSA) will provide payments based on the type of commodity planted to ensure farmers receive a minimum price for their goods. Additionally, he announced a Food Purchase and Distribution Program through the Agricultural Marketing Service (AMS) to buy several types of commodities. The USDA pledged to spend $85 million in 2018 and $68 million in 2019 on the purchase of dairy products. These government-purchased products are to be donated through nutrition assistance programs (USDA 2018, 2019). a. Using evidence from the effect of the 1977 Farm Bill, predict what will happen to the dairy market as a result of this new price support. b. Would the benefits or consequences of this proposed policy change if we emphasized the fact that this price support would be implemented on the milk market instead of the cheese market? That is, are different costs associated with storing milk than with storing cheese?
