Answer: 97
Explanation:
The element Ru is <u>Ruthenium</u> which has <u>44 protons</u>.
In this case, our atom is an isotope with <u>53 neutrons</u>.
With this information, we can use the mass number formula to find this atom's mass number.
mass number = protons + neutrons
mass number = <u>44 protons</u> + <u>53 neutrons</u>
mass number = <u>97</u>
I would expect silane because all the rest have an overall dipole movement
Nuclear power plants heat water to produce steam. The steam is used to spin large turbines that generate electricity. ... In nuclear fission, atoms are split apart to form smaller atoms, releasing energy. Fission takes place inside the reactor of a nuclear power plant.

8000-16000 0.05 0.03
16000-24000. 0.017. 0.08
24000-32000. 0.22. 0.18

44000. 8800. 11880
52000. 3640 3640
Total=33040g\mol 36240
Note before repeat molecular weight m= 3*12.01+6*1.008=
42.08g/mol
Degree of polymerization= total W*M/w=33040/42.08 =785
<u>Solution and Explanation:</u>
[La3+] = 0.1 M
<u>At the equilibrium:
</u>
La(IO3)3 <----> La3+ + 3 IO3-
0.1 +s 3s
![\mathrm{Ksp}=[\mathrm{La} 3+][\mathrm{IO} 3-]^{\wedge} 3](https://tex.z-dn.net/?f=%5Cmathrm%7BKsp%7D%3D%5B%5Cmathrm%7BLa%7D%203%2B%5D%5B%5Cmathrm%7BIO%7D%203-%5D%5E%7B%5Cwedge%7D%203)
Since Ksp is small, s can be ignored as compared to the 0.1
The above shown expression thus becomes:
<u>Answer: 1.4*10^-4 M
</u>
