Nitrogen 1N22 and hydrogen 1H22 react to form ammonia 1NH32. Consider the mixture of N2 and H2 shown in the accompanying diagram. The blue spheres represent N, and the white ones represent H. (d) Are any reactant molecules left over, based on the diagram?
The reaction between reactant A (blue spheres) and reactant B (red spheres) is shown in the following diagram:
Based on this diagram, which equation best describes the reaction? (a) A2 + B¡A2B (b) A2 + 4 B¡2 AB2 (c) 2 A + B4¡2 AB2 (d) A + B2¡AB2
The following diagram shows the combination reaction between hydrogen, H2, and carbon monoxide, CO, to produce methanol, CH3OH (white spheres are H, black spheres are C, red spheres are O). The correct number of CO molecules involved in this reaction is not shown. (a) Determine the number of CO molecules that should be shown in the left (reactants) box.
The following diagram represents the collection of elements formed by a decomposition reaction. (a) If the blue spheres represent N atoms and the red ones represent O atoms, what was the empirical formula of the original compound?
The following diagram represents the collection of CO2 and H2O molecules formed by complete combustion of a hydrocarbon. What is the empirical formula of the hydrocarbon?
