Chemistry
I haven't done chemistry for a while, but here's my best guess: M = mol/L so 0.120 M means there is 0.12 moles of Ca(NO3)2 in a liter. The question ask for 500 mL, which is half of a litter, so I would just divide 0.12 by two and get 0.06 moles of Ca(NO3)2 in 500 mL. A...

.. 3sqrt6 and sqrt2a^4? So you simplified the problem first as I said above and you get: 3(a^3)sqrt(2a) * 3(a^4)(b^3)sqrt(3) and then you multiply those 2 things together and you get: 9(a^7)(b^3)sqrt(6a)

Plug your 0 into the x in your equation and you get 1 = -1, which is false, which mean: no, the answer is not x = 0. Since you didn't show your work, I have no idea what you did wrong on your process... or maybe you just guess 0 and didn't do any work at all. But I'...

18 = 9 * 2 then sqrt 18 = 3sqrt2 sqrt a^7 = a^3 * sqrt a 27 = 9 * 3 then sqrt 27 = 3 sqrt3 sqrt a^8 = a^4 sqrt b^6 = b^3 Now just multiply the like-terms together.

I meant, I was wondering that too, so thanks even though it isn't my question.

Alright thanks!
Biology
A base pairs with T, G with C. In RNA, A pairs with U and G pairs with C. I think you just need to do some more readings... most of these can be answered in your book or note for sure.

DNA is double stranded. It splited out into two single strand and produce another new strand and that created more DNA. Next, the DNA sequences are translated into amino acids. For every 3 base sequences, that would represent a single amino acid. There are specific sequences f...
