He probability density for the maxwell distribution of molecular speeds is given by the function g(v) = 4π(a/π)3/2 v2 e-av2, with a = m/2rt[some authors use the symbol f(v) or f(v)]. find atkins’(example 24.1) or levine’s(sec. 15.5) calculation of average (mean) speed using the general relationship for the average value of a velocity function, h(v): = ∫0[infinity] h(v)·g(v) dv, which becomes = ∫0[infinity] v·g(v) dv for the case h(v) = v. be sure that you understand the calculation to 3m2mmvcvbvrtp+−= the point of being able to execute it. then show your calculation of the root-mean-square (rms) speed using the relationship, vrms = ½ and = ∫0[infinity] v 2·g(v) dv. most mortals will need to look up a solution for the integral form, 240axx edx[infinity]−

Ineed someone to see if my answers are correct! if any are wrong let me know what the correct answers would be and how to get that answer! 1. how many moles of sodium chloride are in 28 grams od nacl? a. 265 mole naclb. 856 mole naclc. 479 mole of nacld. 1.2 mole nacl < my choice2. 734 grams of lithium sulfate (li2so4) are dissolved to make 2500 ml of solution what is rhe molaratiy? a. 2.67 mb. 4.56 mc. 3.89 m < my choiced. 1.78 m3. how many grams of cacl2 would be dissolved in 3.0 l of a 0.50 m solution of cacl2? a. 250 g cacl2 b. 166.5 g cacl2c. 113.65 g cacl2d. 98 g cacl2 < my choice4. suppose you had 58.44 g of nacl and you dissolved it in exactly 2.00 liters. the molarity if the solution would be 0.5 mtrue < my choicefalse 5. i would need 22g of naoh to make a 3.0 m solution using 250 ml of solvent. true < my choicefalse6. identify the solute: you have a .0195 m solution made from using 6.5 g of solute and 3 l of solvent. identify the solute by solving for molar weight. a. the solute is nacl because the molar weight is 58.43 g/mol < my choiceb. the solute is h2so4 because the molar weight is 98.06 g/molc. the solute is cacl2 because the molar weight is 111.11 g/mol

Match the mixture with the substance// i really need on this guys (it’s a pic btw)

The reactions shown here can be combined to make the overall reaction c(s) + h2o(g) ⇌ co(g) + h2(g) by reversing some and/or dividing all the coefficients by a number. a. c(s) + o2(g) → co2(g) k=1.363×10^69 b. 2 h2(g) + o2(g) → 2 h2o(g) k=1.389×10^80 c. 2co(g) + o2 (g) → 2 co2(g) k=1.477×10^90
