Be sure to answer all parts. three of the complex ions that are formed by co3+ are [co(h2o)6]3+, [co(nh3)6]3+, and [cof6]3−. these ionshave the observed colors (listed in arbitrary order) yellow-orange, green, and blue. match each complex with its color.[co(h2o)6]3+: yellow-orangegreenblue[co(nh3)6]3+: yellow-orangegreenblue[cof6]3−: yellow-orangegreenblue

Use the table to identify the phase and phase changes of the elements under the given conditions. write the name of the substance, phase, or phase change. when the temperature in a room increases from 25°c to 33°c, changes from a solid to a liquid. in a lab, methane and nitrogen are cooled from -170°c to -200°c. the methane freezes and the nitrogen . when gold is heated to 2,856°c it changes from a liquid to a .

The big bang nucleosynthesis theory states that elements were produced in the first few minutes of the big bang while elements have their origins in the interiors of stars, forming much later in the history of the universe.

Answer explain why it is not possible to deduce a complete order of reactivity.
