him/her the label of your calcium carbide box. 4 FOREWORD CONCLUSION 47. 6 EQUIPMENT OPTIONS FOR THE CCM DEVICES The components described in these instructions are not included in every version of the device. Different components are available, depending on the equipment option.
Well to start [math]CaC_2 [/math] has calcium in it which is in group 2 of the periodic table, this makes it ionic. Since, in this case, the molecule contains a metal like calcium, it is an ionic molecule. [math]SiC,[/math] or silicon monocarbide, is covalent. One way of looking at this is that Silicon is a metalloid and therefore acts like both a metal and a nonmetal.
