Si+CO2 ---------> SiC+SiO2
The soil is rich in SiO2 especially sand and clay.
Silicon is just silicone and silicone dioxide is one part silicon to every two parts oxygen.
no real answer is thisfind mols of silicon in 1g = approx. 0.357 then times by RFM of silicon dioxide (60)therefore:2.1428571428574
Which one is mixturecarbon dioxide = compoundsilicon = elementsilicon dioxide = compoundor sand = mixture so sand is the answer.
