Concept explainers
(a)
Interpretation:
The given sets of substance are to be classified as element or compound or mixture.
Concept Introduction:
Element are formed entirely of same type of atom. Elements cannot be further broken down into simpler matter.
Compound is pure substances, which are formed by chemical combination of two or more elements in specific proportion and does not possess the characteristics of its individual constituents. The constituents of compounds can be separated by chemical methods.
Mixtures are impure substances, which are formed by mixing of two or more substances physically in any proportion. The characteristic of mixture will be similar to the characteristic of its individual components. Physical methods are enough to separate the constituents of mixture
(b)

- For the single step reaction: A + B → 2C + 25 kJ If the activation energy for this reaction is 35.8 kJ, sketch an energy vs. reaction coordinate diagram for this reaction. Be sure to label the following on your diagram: each of the axes, reactant compounds and product compounds, enthalpy of reaction, activation energy of the forward reaction with the correct value, activation energy of the backwards reaction with the correct value and the transition state. In the same sketch you drew, after the addition of a homogeneous catalyst, show how it would change the graph. Label any new line "catalyst" and label any new activation energy.arrow_forwardHow many grams of C are combined with 3.75 ✕ 1023 atoms of H in the compound C5H12?arrow_forwarde. f.
