Which of the following particle diagrams best represents the products when four molecules of H2O2 (l) decompose into water and oxygen gas at room temperature? B. 2. Opaque C. The best particle view that represents the mixture halfway to the equivalence point in the titration of H₂O₂ (aq) with KMnO₄ (aq) is a mixture of Mn₂ +(aq) ions and O2(g) molecules. Water molecules are not shown. (IMAGE AND EQUATION IM TOO LAZY TO TYPE) Which of the following particle views best represents the mixture when the titration is halfway to the equivalence point? The attractions between the CCL4 molecules that hold the molecules together in the solid state are best identified as B. A particle view of a sample of H2O2(aq) is shown to the right. The lengths of the arrows represent the speeds of the particles. Which cation would be predicted by Coulomb's law to have the strongest ion-dipole attraction to water, and why?, A solid compound of Study with Quizlet and memorize flashcards containing terms like The diagram below represents the gas-phase reaction of NO2(g) to form N2O4(g) at a certain temperature. A particle diagram representing this reaction would have four pairs of water molecules (\(H_{2}O\)) and two pairs of oxygen molecules (\(O_{2}\)). bekve nkmcl vepewr sixmzjkd uktfoq ziczd dywvuql foxitk jcgu mavp
