Abstract In this study simple, economic and rapied potentiometric method was used to calculated proton-ligand stability constant of [2-oxo-2H-chromene-3-carbohydrazide] and metal-ligand stability constant of its complexes with metal ion (Mn+2 and Cd+2). This method has been employed at three different temperatures 298k,308k and 318k and at an ionic strength of 1N NaCl. The thermodynamic parameters (G, (H and (S were studied from logk at three different temperatures. Introduction Coumarin derivatives

complex, known as hexol, into optical isomers, overthrowing the idea that solely carbon compounds may possess chirality. Introduction Coordination compound is ‘a compound formed from a Lewis acid and a Brønsted base’, a Lewis acid being an electron pair acceptor and a Brønsted base a proton acceptor. Thus the interaction of the Lewis acid metal centre as in Ni(ClO4)2 with the Brønsted base ammonia to make a complex in line with the given equation: Ni(ClO4)2 + 6NH3 →

If anything, the lone wolf adopts his dangerous mindset through shutting himself off from

Levine, Ph.D. In Sherman Alexie’s collection of short stories, The Lone Ranger and Tonto Fistfight in Heaven, we read stories of Native American struggles for survival in an American society designed to keep Native Americans locked in the cycle of intergenerational trauma. Alexie illustrates the importance of rejecting intergenerational trauma as a method of survival, by isolating the two main causes intergenerational

I position myself and the sound of my club sweeping across the grass fills the air as I practice my swing. I wipe my sweaty palms on my shorts to stop the club from slipping. Feeling confident I square myself up with the ball and ground my feet into the short soft grass. I turn my shoulders, raise my club, and turn through my
