The number in isotope platinum-194 stands for the <em>total </em>amount of protons and neutrons. In other words, this is the mass. =)
The computation for molarity is:
(x) (0.175 L) = 0.0358 g / 598 g/mol
x = 0.000342093 M
Whereas the osmotic pressure calculation:
pi = iMRT
pi = (1) (0.000342093 mol/L) (0.08206 L atm / mol K) (298 K)
pi = 0.0083655 atm
Converting the answer to torr, will give us:
0.0083655 atm times (760 torr/atm) = 6.35778 torr
which rounds off to 6.36 torr
Answer:
a)decrease
b)increase
c)smaller
d)smaller
Explanation:
Ionization energy decreases down the group due to increase in the atomic radius. The distance between the outermost electron and the nucleus increases hence the nuclear attraction for the outermost electrons become smaller and the ionization energy also become smaller as electrons are now easily removed from the outermost shell.
Hence the group of answer choices provided above.
Answer:
Limited
Explanation:
Once it is used once, it is not reusable. Also, there's a possibility to use ALL the coal there is. That's why it's an unrenewable source, unlike the sun, wind, or water that never ends. Those are renewable
I think its CuCO3+NaNO3 but idk if its right
