A student is given a 2.00-g mixture of sodium bicarbonate, anhydrous citric acid and corn starch. The student places all 2.00 g of the mixture in a gel capsule inside an Erlenmeyer flask and sets up a gas collection apparatus like below. She then adds 10.0 mL of 2.0 M HCI to the flask and quickly places the rubber stopper over the flask. Once the reaction is complete, the student collects 6.0 x 10-3 moles of dry carbon dioxide gas. She then titrates the leftover solution with 1.0 M NaOH and phenolphthalein as the indicator. The initial volume reading from the buret is 0.00 mL. The solution reaches its endpoint at 17.35 mL. A. Write the balance chemical reaction for citric acid and sodium bicarbonate
B. Write the balance to Chemical reaction for hydrochloric acid and sodium bicarbonate
C. What was the mass of each component in the original 2.00 g mixture show all work
D. In another sample of the same mixture after adding 10 mL of 2.0 M HCl a student from the sodium bicarbonate to be approximately .45 g of the 3.00 g solution when the remaining make sure it was titrated it took 23.40 mL of the 1.0 M NaOH to reach the endpoint what was the amount of citric acid in the ex show all work

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
