Answer the following question given this paragraph:   yellow liquid used in the production of synthetic rubber. Its condensed structural formula is ClSSCl. Ethylene glycol is the major ingredient in antifreeze. Its condensed structural formula is HOCH2CH2OH. Trimethylamine is one of the substances responsible for the smell of spoiled fish. Its condensed structural formula is (CH3)3N. Given: condensed structural formula Asked for: molecular formula Strategy: A Identify every element in the condensed structural formula and then determine whether the compound is organic or inorganic. B As appropriate, use either organic or inorganic convention to list the elements. Then add appropriate subscripts to indicate the number of atoms of each element present in the molecular formula. Solution: The molecular formula lists the elements in the molecule and the number of atoms of each.   Q: Trimethylamine is one of the substances responsible for the what of spoiled fish?   A:

Answer: smell

Answer the following question given this paragraph:   A rate is a measure of how some property varies with time. Speed is a familiar rate that expresses the distance traveled by an object in a given amount of time. Wage is a rate that represents the amount of money earned by a person working for a given amount of time. Likewise, the rate of a chemical reaction is a measure of how much reactant is consumed, or how much product is produced, by the reaction in a given amount of time. The rate of reaction is the change in the amount of a reactant or product per unit time. Reaction rates are therefore determined by measuring the time dependence of some property that can be related to reactant or product amounts. Rates of reactions that consume or produce gaseous substances, for example, are conveniently determined by measuring changes in volume or pressure. For reactions involving one or more colored substances, rates may be monitored via measurements of light absorption. For reactions involving aqueous electrolytes, rates may be measured via changes in a solution’s conductivity. For reactants and products in solution, their relative amounts (concentrations) are conveniently used for purposes of expressing reaction rates. If we measure the concentration of hydrogen peroxide, H2O2, in an aqueous solution, we find that it changes slowly over time as the H2O2 decomposes, according to the equation: 2H 2 O 2(aq) ⟶ 2H 2 O(l) + O 2(g) The rate at which the hydrogen peroxide decomposes can be expressed in terms of the rate of change of its concentration, as shown here: change in concentration of reactant time interval ⎡ ⎤ ⎡ ⎤ − ⎣H 2 O 2⎦ t ⎣H 2 O 2⎦ t 1 2 = − t2 − t1.   Q: What kind of variation does a rate measure?   A:

Answer:
property to time
