Is Pb(NO3)2 soluble in water? What is a supersaturated solution? A) If 0.0067g CaCO3 soluble in 1.0L of water, calculate the molar solubility and the Ksp. B) Will mixture precipitate if equal volumes of 3.0 times 10^(-3) M Ba^2+ and 2.0 times 10^(-3) M CO3^2- mixed? Ksp...
Proteins with a metallo-beta-lactamase (MBL) fold have been largely studied in bacteria in the framework of resistance to beta-lactams, but their spectrum of activities is broader. We show here that the giant Tupanvirus also encodes a MBL fold-protein that has orthologs in other giant viruses...
