Someone please help me with this chemistry homework :( It's three questions. 10) A balloon is filled with 0.93 L of gas at a pressure of 1.15 atm and a temperature of -22oC. What is the temperature, in oC, when the volume is 0.85 L and the pressure is 1.01 atm?

11) How many grams are in 563 mL of chlorine gas at STP?

12) What volume in mL will 0.0066 mol of hydrogen gas occupy at a pressure of 0.907 atm and a temperature of 9 oC?

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
