What conclusions do you think Dobereiner would have made if he had tried to compare F,Cl, & Br as a triad instead of Cl, Br, and I? Using the modern periodic table , explain why F,Cl, & Br would not have fit his scheme. Would he have found P, As, and Sb to be a triad? What about As, Sb, and Bi> Explain your answers

A ball of radius 11 has a round hole of radius 5 drilled through its center. Find the Volume of the resulting solid?

I think we have to use the circle equation; y^2+x^2=r^2. Radius would be 11. It don't know whether to use the shell method or the disk method. Thanks

Hey today my science teacher showed us a demonstration of water boiling. He used 4 flasks and they all had water in them. 3 of them did not boil when we had put it under a Bunsen burner however when we placed one of the flask, it had started boiling in like 5 second and after that we placed it under a faucet running cold water and it also started boiling. Anyone know why? All of the flasks had a cork on the top and they were all water nothing else inside of them, he even drank each one and so did others to prove that all of them was water.

The last time I asked, people told me that it was due to the difference in surface area. That explanation doesn't make sense to me, because I thought that sliding friction was independent of surface area.

The US plans on having an occupied base on the moon by 2024 or something. Other countries were invited, and the Russians already say they want in. Besides exploring, and doing it for the sake of doing it, what is the economic incentive? Columbus & Magellan didn't go on their voyages just to go sailing. They did it for money. Oil companies don't send geologists into jungles or the artic just for fun, they do it to look for oil, so the companies can make money.
I can understand if this planned moon base is supposed to be a stepping stone to say, hypothetically, mining diamonds on Mars, or tapping Jupiter's atmosphere for rocket fuel. But is that the only reason, to use it as a stepping stone to someplace else?
Yeah, I know, the Earth is getting overpopulated, we need to spread out, and Hawking said that humans have to leave Earth to survive. But, if going to the moon was so important, corporations would be getting together to make their own base.
