RL, a 28-year old first time father, was watching his 4-month old baby for the weekend while his wife was away at a sales meeting. Things were going well. He had run out of breast-milk to give the baby, so he went to the store to get some formula. The baby responded well to the formula - consuming an entire bottle in one feeding. In an hour or so he noticed a smell and figured it was time to change the baby's diaper. To RL's horror, the baby had a very wet diaper (to include diarrhea) and a bright red rash all over her butt. After he cleaned up the mess, he looked around the baby's changing table for remedies for this horrible rash, but he couldn't find anything. As he was about to panic, he remembered some useful acid-base chemistry from a class years ago. He opened the refrigerator where he expect ed to find a box of baking soda; but none was to be found. As he was looking for the baking soda he found something else that would help alleviate the rash. What could've AJ used to help with the diaper rash? From a chemical standpoint, how does it work?
Use your favorite word processing software to write an essay that answers and explains the situation. Do not be afraid to some web searches to help with your answer. If you rely on calculations in determining your answer you must describe or include them in your essay. Please be mindful of your spelling, punctuation, and sentence structure as you write your response. Your response should be of sufficient length in order to adequately respond.
Determine if the following reactions will form a precipitate when mixed. If one is formed, write the BALANCED formula unit, the COMPLETE IONIC, and NET IONIC equations. If a precipitate doesn't form, write NR for no reaction
Write the Lewis-dot structure for the following species. If resonance occurs, draw all resonance forms. Give the formal charge and oxidation number of each atom in each species.
We sometimes use complex formation to make relatively insoluble salts more soluble. For instance, AgCl(s) has Ksp=1.6x10^-10. Silver ions can form complexes with the thiosulfate ion
