A chemical reaction occurs when a chemical converts into another substance. Synthesis is one of the main types of chemical reaction. Synthesis means that two elements combine to make something new. In a synthesis reaction, also known as a direct combination reaction, two chemicals (sodium and chloride) make a new substance (sodium chloride - table salt). The rate of the reaction is proportional to the product of the instantaneous amounts of sodium and chloride not converted to sodium chloride. In the beginning, there are 40 grams of sodium and 50 grams of chloride, and for each gram of chloride, 2 grams of sodium are used. It is observed that 10 grams of sodium chloride is formed in 5 minutes. a. Compute the amount of sodium chloride formed in 20 minutes. b. Calculate the maximum capacity of sodium chloride after a long time? c. Calculate the remaining amount of sodium and chloride after a long time d. If 100 grams of sodium is present at start, examine when will the sodium chloride becomes half-formed?

Substances that poison a catalyst pose a major concern for many engineering designs, including those for catalytic converters. One design option is to add materials that react with potential poisons before they reach the catalyst. Among the commonly encountered catalyst poisons are silicon and phosphorus, which typically form phosphate or silicate ions in the oxidizing environment of an engine. Group 2 elements are added to the catalyst to react with these contaminants before they reach the working portion of the catalytic converter. If estimates show that a catalytic converter will be exposed to 625 g of silicon during its lifetime, what mass of beryllium would need to be included in the design?

Iodomethane (CH3I) is a commonly used reagent in organic chemistry. When used properly, this reagent allows chemists to introduce methyl groups in many different useful applications. The chemical does pose a risk as a carcinogen, possibly owing to iodomethanes ability to react with portions of the DNA strand (if they were to come in contact). Consider the following hypothetical initial rates data: [DNA]0 ( mol/L) [CH3I]0 ( mol/L) Initial Rate (mol/Ls) 0.100 0.100 3.20 104 0.100 0.200 6.40 104 0.200 0.200 1.28 103 Which of the following could be a possible mechanism to explain the initial rate data?

The label on a bottle of 3% (by volume) hydrogen peroxide, H2O2, purchased at a grocery store, states that the solution should be stored in a cool, dark place. H2O2decomposes slowly over time, and the rate of decomposition increases with an increase in temperature and in the presence of light. However, the rate of decomposition increases dramatically if a small amount of powdered MnO- is added to the solution. The decomposition products are H2O and O2. MnO2 is not consumed in the reaction. Write the equation for the decomposition of H2O2. What role does MnO2 play? In the chemistry lab, a student substituted a chunk of MnO2 for the powdered compound. The reaction rate was not appreciably increased. WTiat is one possible explanation for this observation? Is MnO2 part of the stoichiometry of the decomposition of H2O2?
A reaction is started by mixing reactants. As time passes, the rate decreases. Explain this behavior that is characteristic of most reactions.
