Nevermind I think i figured it out. But CaCO3 is supposed to react with water in the presence of CO2
Ooh I forgot about that one. thank you
nevermind I got it
lysosomes they are organelles, though. I don't know if you meant cell or organelle. if you meant cell, I don't know the answer
Yes. Muscle cells use energy and need lots of ATP so it has large numbers of mitochondria
That is correct. The radius increases down and to the left of the periodic table
that doesn't mean it's convergent, necessarily. but i found it is actually convergent because if you divide by 1/2^n, which is also a positive term series, you get 9, which means the series is convergent.
76 and 100 are both divisible by 4 76/4 = 19 100/4 = 25 therefore 76/100 = 19/25
I don't need the limit, I just want to know how to show it is in the indeterminate form.
nvm i think it is absolutely convergent
Squeeze law? then the limit is 0 right? -pi/sqrt(1-x)
Yes. I found that the limit of the sequence goes to 0 and that it is a positive term series. Now what do I do?
27) 10^-3 = x x = .001 28) yes 29) take ln of both sides. xln(8)= ln(5.2) x = ln(5.2)/ln(8) ~ 0.7928 30) raise both sides to the e e^ (lnx) = e^(5/8) x=e^(5/8) ~ 1.868
for the first one I got 332 kJ/mol E = hc/lamda E = (6.626E-34)(2.998E8)/(360E-9) E = 5.522 J To convert it to kJ/mol, multiply by 6.022E23 and divide by 1000 to get 332 kJ/mol
300/8 x 100 = 37.5 x 100 = 3750%
2y = 6 - 5x y = 3 - 5/2 x this is in the form y = mx + b where m is the slope and b is the y-intercept. therefore -5/2 is the slope, 3 is the y-intercept
