Write the balanced chemical equation for the neutralization reaction that occurs when an aqueous solution of nitric acid (HNO3) is mixed with an aqueous solution of sodium hydroxide (NaOH).
Indicate the physical states of the reactants and products using the abbreviations (s),(l) ,(g) or (aq) for solids, liquids, gases, or aqueous solutions, respectively.
calculate the root-mean-square speed of Ne atoms at the temperature at which the average kinetic energy
When a sample of aqueous hydrochloric acid was neutralized with aqueous sodium hydroxide in a calorimeter, the temperature of 100.0 g of water surrounding the reaction increased from 25.0°C to 31.5°C.
a gas sample containing 1.50 mol at 25 exerts a pressure of 400 torr. some gas is added to the same container and the temperature increased to 50 C. If the pressure increases to 800. torr, how man moles of gas were added to the container? assume a..
