A chemist determines by measurements that 0.0850 moles of iodine solid participate in a chemical reaction. Calculate the mass of iodine solid that participates. Be sure your answer has the correct number of significant digits.
The temperature of the acid solution increases from 24.2 oC to 29.9 oC. Calculate deltaH for the reaction that occurred.
If a piece of rock that has a volume of 0.73 L and a mass of 1524 g, what is the density of the rock in g/mL?
Problem- Who has the shorter wavelength when running at the same speed- a person weighing 60 kg or a person weighing 80 kg. Explain your reasoning
In the experiments described in Problems 21.10 and 21.11 an inverse temperature dependence of the reaction rate was observed, the overall rate of reaction at 70 degrees C being approximately one-third that at 19 degrees C.
For combustion of hydrogen gas the standard enthalpy of reaction is -286 kJ/mol and the standard Gibbs free energy of reaction is -237 kJ/mol at 298 K and 1 bar.
For the reaction 2C6H6 + 15O2 → 3CO2 + 6H2O 30 grams of C6H6 are allowed to react with 79.09 grams of O2.
