The addition of hydroiodic acid to a silver nitrate solution precipitates silver iodide according to the reaction: agno3(aq)+hi(aq)→agi(s)+hno3(aq) when 50.0 ml of 5.00×10−2m agno3 is combined with 50.0 ml of 5.00×10−2m hi in a coffee-cup calorimeter, the temperature changes from 22.40 ∘c to 22.91∘c. calculate δhrxn for the reaction as written. use 1.00 g/ml as the density of the solution and cs=4.18j/(g⋅∘c) as the specific heat capacity of the solution. express the energy to two significant figures and include the appropriate units

Complete the following reactions using word and balanced equations including states. dilute phosphoric acid is added with a calcium hydroxide solution.

Problem #3 (ch. 1, problem 15)the ideal gas law provides one way to estimate the pressure exerted by a gas on a container. the law isí‘ťí‘ť=푛푛푛푛푛푛푉푉mo re accurate estimates can be made with the van der waals equationí‘ťí‘ť=í‘›í‘›í‘›í‘›í‘›í‘›í‘ ‰í‘‰â’푛푛푟푟â’푞푞푛푛2í‘ ‰í‘‰2where the term nb is a correction for the volume of the molecules and the term an2/v2is a correction for molecular attractions. the values of a and b depend on the type of gas. the gas constant is r, the absolutetemperature is t, the gas volume is v, and the number of moles of gas molecules is indicated by n. if n = 1 mol of an ideal gas were confined to a volume of v = 22.41 l at a temperature of 0â°c (273.2k), it would exert a pressure of 1 atm. in these units, r = 0.0826.for chlorine gas (cl2), a = 6.49 and b = 0.0562. compare the pressure estimates given by the ideal gas law and the van der waals equation for 1 mol of cl2 in 22.41 l at 273.2 k. what is the main cause of the difference in the two pressure estimates, the molecular volume or the molecular attractions?
