Ok I have a question about evolution. They say humans came from monkeys(sp) right? Well why are there still monkeys then? Did evolution decide to take a little nap? How could we have came from a monkey if monkekys don't have souls? They are classified as animals not humans. If we evolved from monkeys then how come the monkeys are still here and haven't evolved? If you can answer this I appreciate it, but I doubt you can convince me that I came from a monkey. I only came from one place. If you recommend this question for someone to answer please star it! Thank you.

would the cable be taught as the force of the earth spinning pull the anvil out or would it be slack as the anvil and or the cable is pulled to earth by gravity. I think this has something to do with centrifugal and centripetal forces but I'm really not sure.

2.29 mL of concentrated sulfuric acid (specific gravity 1.84) is added to mass of 0.1978 kg of water. The sulfuric acid solution is then titrated with NaOH and no. of mol of NaOH that reacted with H2SO4 is 0.0092 mol.

How do you calculate the molality of the acid produced by the dilution?

Can anyone pls help? Thanks a lot
