    Make ##delta epsilon/5##. We believe that ##lim_(xrarr2)(5x-7)=3##. To show this, we need to show that we can make ##abs((5x-7)-3) epsilon## by making ##abs(x-2) delta##. We observe that: ##abs((5x-7)-3)=abs(5x-10)=abs(5(x-2))=abs(5)abs(x-2)=5abs(x-2)##. Makng ##abs((5x-7)-3) epsilon## ca...

  • Waiting for answer How can I find the percent compositions of CuBr2?

    So, you would first start by finding the molar mass of CuBr2. Mass of Cu: 63.546 Mass of Br: 79.904 So you take the molar mass: 1(63.546) + 2(79.904) = 223.354 (Remember there's a 2 in front of the of Br due to its subscript.) After taking the molar mass, you can start solving for percent com...
