ACS General Chemistry Unit 8 Acids-Bases Multiple Choice 82 Questions with Verified Answers In pure water, some of the molecules ionize according to the equation H2O ⇌ H+ + OH− The extent of the ionization increases with temperature. A student heats pure water and records the measured pH at 50°C as 6.6. Based on this information, which of the following mathematical relationships gives the pOH of pure water at 50°C ? - CORRECT ANSWER pOH = pH In pure water, some of the molecule...

Briefly explain how the base pairs A-T and C-G bond to each other and why the interactions they form are important to DNA unwinding. Base pairs form hydrogen bonds to each other. G and C form 3 hydrogen bonds, while A and T form 2 hydrogen bonds. These hydrogen bonds are weak electrostatic interactions that are able to hold the DNA together but are easily broken for the DNA to unwind. Why are telomerase inhibitors an attractive prospect for cancer therapies? >90% of cancer cells expres...
