i know the relative reactivity of metals increase as you go down the period table, and the relative reactivity of nonmetals decrease as you go down. but what about metalloids?

I REALLY do not believe that an explosion just happened and created the universe.. It just sounds.. Off to me.. (Or if im wrong, then i meant the planets)

Can you explain or try to explain in your theory how you think the planets, universe, and everything else was made?

And answer the topic question ;P

If its endless... Well... I just dont understand... Nothing can be endless right? Unless its like a circle going back and fourth...

I have to do this thing for my astronomy class where we are in groups and we drew either a moon or a planet out of a hat. My group got Venus. I'm not asking you to do my homework or anything. I'm just asking your opinion. Do you think human life could be supported on Venus? It is the 2nd closest planet to the sun, and therefore very very hot. Although sometimes it is called Earth's "sister planet"?

I life in Connecticut and it has been in the fourties and lower fiftees for the past three weeks. It has not snowed AT ALL. It seems that this winter will be snowless and warm. Why is this? Why is the eastern seaboard so hot this year? Is there a chance it will snow at all this winter?

I have a friend trying to figure out a probability problem with animal measurements.

Say you have 18 mini horses that are measured in inches, (1/4" increments). How would you calculate the probability that 9 of the 18 were 28 inches tall? The height range is 27" - 28" (measured in 1/4" increments - 5 slots).

Thanks in advance for your help!

aliens do u believe (i do) if u do, what gives u that belief. e.g. the reason i believe is all the stars in the whole universe even if only 20% have planetary systems around them, then we are talking 1000's. and in these planetary systems if only 5% have a planet capable of supporting life then we are talking 100's. i refuse to believe that all of those planets are void of life.

it is my experience that if sufficient heat is applied to a kernal and it fails to pop, then it must lack the necessary water content to actually pop... who knows?

a friend used to recommend storing the kernals in a jar of water to maintain the moisture level... does this decrease the failure rate?

How do you determine the standard enthalpy change of the reactions when you are given the following equations?

For example,

Ba(s) + O2 (g) + H2(g) -->Ba(OH)2 (s),
and enthalpy change (delta H) = -946kJ
