In 1777, George Washingtion's amy received a loan of $450,000. Interest rate is 6%
How much was owed on the loan in 1989?

This is how i did it.
1989-1777= 212 years. If one year is 6%, then 212(6) is1272%.

$450,000*12.72= $5,724,000.

Is it right?

and calcium hydroxide?
what does that form?
i think it makes H2SO3+CaO?
which breaks down to H2O+SO2+CaO?
so the overall equation is
SO2+Ca(OH)2--->H2O+SO2+CaO
is this correct?
it doesnt have to be balanced.

Hi there!

I am from The Netherlands and was wondering if you could enlighten me about an experience that I've had.

Aprox. 2 years ago when I was doing busines with an investor from within an internet café for young people on a "silent" moment a girl standing behind me together with 2 other girls who were doing nothing a for a moment suddenly called out that she smelled "sigars" while ofcourse noone was smoking a sigar and nobody ever smoked sigar in there. The people in the room acknoledged her but did not have an explaination for her and didn't say anything about it.

When I was doing business with this investor, I smelled the smell of sigars myself often. I smelled the smell of money, however that may smell when doing business with some other investors over the internet.

The girls were standing like 3-4 meter behind me. The other people were bussy on the computers.

Looking forward to any explaination for this.

Best Regards,
Science Japan
