since we are given the moles for Co and O, we'll divide both of those moles by the lowest mole quantity, which is, in this case, 2.59. After dividing, we see that the ratio of O to Co is 2:1. So, for every 1 Co atom, there has to be 2 O atoms. we can then insert the 2 in for OH to satisfy this ratio.
I think it's B) only powerful...
Answer: False
Explanation: Endothermic means it absorbs heat energy.
Answer:
O.2006 M
Explanation:
M1V1 =M2V2
M1 = M2V2/V1 =0.150M*32.1 ml/24.0 ml = 0.2006 M
