Calculate the pH for the following buffer solutions with steps. 1. 7.4862 grams of acetic acid and 10.4695 grams of sodium acetate are dissolved in enough deionized water to make 250.0 mL of solution.

2. 11.8115 grams of trimethylamine and 18.7088 grams of trimethylammonium chloride are dissolved in enough deionized water to make 500.0 mL of solution.

Thank You:)

Electromagnets coils of wire paper clips picked up 10 3 15 6 20 9 25 12 ms. owens' class was studying magnets. ms. owens showed her students how to make an electromagnet using a nail, a d-cell battery, and plastic coated wire. the students wrapped the wire around the nail and then attached the ends to the battery. when they were finished, they tested their magnets by investigating how many paperclips their magnets could pick up. they also tested whether they could increase the strength of their electromagnets by using more coils of wire. they recorded the class average of their results in the data table seen here. ms. owens asked her students to graph their data in a line graph. how should the students label the x-axis on their line graph? a) size of battery b) number of paper clips c) number of coils of wire d) strength of electromagnet

2-bromo-2-methylbutane undergoes an e1 elimination reaction in the presence of ethanol. in the next reaction only one of the possible products is represented. although the product shown is not the major product of the reaction, notice that there is more than one way it can be produced. complete the mechanism and draw the missing substances.

Which is the most concentratic acid
