If 1 mole of a van der Waals gas for which it might be shown that , spread out is o thermally from a volume of two litres to a volume of twenty litres. Compute ΔU for the transformation; a = 0.136 m6Pa mol-2 ; b = 0.0391 L/mol.
what is the volume of the drink (in mL) required to meet the RDA?
The sun produces energy via fusion. One of the fusion reactions that occurs in the sun is How much energy in joules is released by the fusion of 3.06 of hydrogen-1
Given the acid is diprotic and its pKa is 1.90 and 6.70, estimate the PH after 10 mL of base are added? After 20 mL basea added? After 30 mL Base added?
From 5g of benzopinacol you obtained benzopinacolona 75% crude. The yield after recrystallization was 2 grams. benzapinacol molecular weight = 366.46 g / mol benzopinacolone molecular weight = 348.44 g / mol determine:
