Drag each statement to the correct location on the chart. Classify the sentences based on the chemical reactions they describe. When a clam shell (CaCO3) is heated, carbon dioxide (CO2) is given off and a white powder, calcium oxide (CaO), forms.> Nitrogen pentoxide (N2O5) is an unstable gas that changes to nitrogen dioxide (NO2) and oxygen (O2) at room temperature. Sodium (Na) reacts with chlorine (Cl) to give sodium chloride (NaCl). Zinc (Zn) metal reacts with copper sulfate (Cu2SO4) to give zinc sulfate (ZnSO4) and copper (Cu). A strip of magnesium (Mg) burns brightly in oxygen (O2) to form a white powder, magnesium oxide (MgO). On heating iron ore (Fe2O3) with carbon (C), we get iron (Fe) and carbon dioxide (CO2).
