Abstract. The reactions of H atoms with C, O, CO, and CH 3 CN in solid phase at 12 K were investigated by temperature-programmed mass spectrometry. In the reaction of H atoms with C atoms trapped in the CO matrix, H atoms migrate in the CO matrix and react with trapped C atoms selectively to form CH 4.D 2 O was the major product from the reactions of D atoms with O atoms trapped in a N 2

Double replacement reactions (double displacement
Double replacement reactions have two ionic compounds that are exchanging anions or cations. Precipitation reactions and neutralization reactions are two common types of double replacement reactions. Precipitation reactions produce an insoluble product from two aqueous reactants, and you can identify a precipitation reaction using solubility rules.
