In lab, you will experiment with three solutions ‒ di water, ethanol, and 4m cacl2 ‒ to develop a method to separate 6 types of plastic. what ideas do you have about possible methods to separate the plastics using these solutions? how could you change the densities of the solutions that are provided? how could you group the types of plastics to work out a separation method?

answer; blank (1); /// (2)///(3)///highblank(4)//low;

the answer is   c.) 1575 j.

explanation:

they are both synthetic elements

explanation:

d

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
