A student is given an unknown aqueous sample containing one of the three ions, Al3 , Ba2 , or Mg2 . There is limited unknown so the student can only run a couple of tests. Select all tests, based on the tables above, that will not provide useful information, even when performed correctly, to identify ions present in the unknown. Group of answer choices Na2CO3 Na2SO4 NH3 NaOH KI

it's 3.2 on edge, i just took the test.

rosa was looking for patterns to predict the products of chemical reactions. she recorded three similar decomposition reactions in the table.she should record 2licl + 3o2.

in the last row of the table. it is the thermal decomposition of chlorate lithium, hence, she should record these products as: lithium chloride ( 2licl ) and oxygen ( 3o2 )   2 > 2 licl + 3o2.
