How many grams of baking soda, NaHCO3, are needed to react with 205 mL of stomach acid having an HCl concentration of 0.07378 M? The reaction is NaHCO3(aq) + HCl(aq) ? NaCl(aq) + CO2(g) + H2O(l).
Place the following in order of increasing strength as reducing agents (all under standard conditions). (Use the appropriate symbol to separate substances in the list.) Cr3+, H2, Zn, Li, F -, Fe2+
A piston exerting a pressure of 1.00 atm rests on the surface of water at 25 degrees C. The pressure is reduced reversibly such that 10.0 g of water evaporated and adsorbed 22.2 kJ of heat. Calculate w, q, change in U and change in H.
List all compounds that are present when reaction is complete. C) Determine the theoretical yield of H3PO4 based on the starting materials and D) Determine the mass, in grams, of each compound present when the reaction is complete

The final temperature of a mixture of solution prepared by dissolving 2.50 gram of NaOH in 75.0 mL of water (both initially at 25 degrees C) increases to 25.5 degrees C. Is this process exothermic or endothermic. What is the enthalpy of solution o..
Use the data given to calculate an overall energy change (in kilojoules per mole) for the formation of CsF2 from its elements.
Explain why the wavelength of light fluoresced by a molecule is longer than the exciting light (absorption) but light fluoresced by an atom is the same wavelength as the exciting light
The enthalpy change for any reaction can be obtained by subtracting the sum of the enthalpy changes of formation of the reactants from the sum of the enthalpy changes of formation of the products.
