Decomposition,because 1 breaks down into 2
Magnesium is the correct answer
Mixtures can be classified as <u>homogeneous </u>or <u>heterogeneous</u>.
Following the law of conservation of mass, the mass percent of hydrogen in the resulting compound is 14.4%(wt/wt). This is assuming that all of the carbon reacts with all of the hydrogen. The solution is as follows:
mass % = mass hydrogen*100/total mass = 28.8*100/(28.8+171.2) = 14.4%
