Answer:
well the first one is something i can get but the second one is something you can google up but here's he first one i tried:
It represents 50, 55, and 65.
3: It effected the speed as if it was heaver it would be harder to pick up and faster than a slow light object like a feather or a lego
alright i tried hard as i can, sorry if i end up putting in the wrong
awnser
sleep well ^-^
Convection occurs because the oceanic waters heat up becoming less dense. .This water moves above the cooler water, and give off its heat to the surrounding environment. As it cools, it begins to sink, and the process begins again.
Let's start by declaring what we know.
15.0 mg = 0.0150 grams
Molecular formula of Prozac is C17H18F3NO
We can calculate the number of grams per mole by adding the molecular weights of the composing elements times the respective quantity of that element
Molar mass of carbon = 12.01 g/mol (17 carbon atoms)
Molar mass of hydrogen = 1.01 g/mol (18 hydrogen atoms)
Molar mass of fluroine = 19.00 g/mol (3 fluorine atoms)
Molar mass of nitrogen = 14.01 g/mol (1 nitrogen atom)
Molar mass of oxygen = 16.00 g/mol (1 oxygen atom)
The molar mass of prozac = 17(12.01 g/mol) + 18(1.01 g/mol) + 3(19.00 g/mol) + 1(14.01 g/mol) + 1(16.00 g/mol) = 309.36 g/mol
Now, we have the number of grams (0.0150 grams), and we have the number of grams per mole of a substance (309.36 grams/mole). To get the number of moles, we have to divide the mass of prozac we have, by the mass per mole of prozac.
(0.0150 grams)/(309.36 grams/mole) = 4.85 * 10^-5 moles of prozac
it's A. here is the formule for kinetic energy :)
