Read the descriptions below of two substances and an experiment on each, Decide whether the result of the experiment tells you the substance is a pure istance or a miature, if you can. - Sample A is 100.g of a course grey powder with a faint unpieasant smell. IS, mg of the powder are put into a very thin tube and heated, The powder begins melting at 66.2C. The temperature continues to rise as the powder slowly melts, and the last of the powder becomes liquid at 76.0 . C. - Sample B is a solid rellow cube wth a total mass of 50.0g. The cube is put into a pressure chamber and the pressure raised by pumping in nitrogen gas. At a pressure of 55 . atm an orange liquid is observed seeping from the cube. After 30 minutes this flow stops, and the smaller and lighter-colored cube sits in a pudde of orange liquid without further change. is sample A made from a pure substance or a mixture? If the description of the substance and the outcome of the experiment isn't enough to decide, choose "can't decide." Is sample 8 made from a pure substance or a mixture? If the description of the substance and the outcome of the experiment isn't enough to decide, choose "can't decide:" pure substance mixture (can't decide) pure sutitance moxture (cant decide) Read the descriptions below of two substances and an experiment on each, Decide whether the result of the experiment tells you the substance is a pure istance or a miature, if you can. - Sample A is 100.g of a course grey powder with a faint unpieasant smell.
