Explain how an increase in the amount of dissolved CO2 in ocean water results in a decrease in the pH of ocean water.
what is the global pH change incurred after injection of the HCl? What would the pH change be if the same amount of 1.000 M HCl were put into a gallon of pure water?
how many moles of CO2 are produced when 5.40 mol of ethane are burned in an excess of oxygen
A hydrolysis reaction in which substrate is converted to products is catalyzed by an enzyme. the reaction was determined to have a Kcat of 10000 s^-1 and a standard free energy change of -13.8 kJ/mol. answer the following questions about experimen..
The rate of reaction indicates the speed at which the reaction can occur. It can be expressed in terms of a change in the concentration of reactants or products per unit of time
