Answer:
- The fuel for nuclear fusion is often uranium
- Nuclear fusion is used to generate electricity at nuclear power plants
Explanation:
The most common nuclear fuel is made up of fissile elements such as Uranium, Neptunium, Plutonium, Americium and Curium, which are fissionable elements, which is when its nucleus is capable of undergoing a fission with neutrons free of any energy.
Nuclear fission can be used both for warlike purposes, as in the construction of atomic bombs, as well as for pacifist purposes, in the construction of reactors for the production of electrical energy.
Answer:
pH = 10.113
Explanation:
Here, we can find pOH first:
pOH = ![-log([OH^-])](https://tex.z-dn.net/?f=-log%28%5BOH%5E-%5D%29)
= 3.886.
Then, we can find pH which is 14 - pOH. We then get the answer above.
Answer:
1.096g
Explanation:
You must know the atomic mass of Hydrogen, Fluorine, and Sodium before you can start:
Hydrogen: 1.008g/mol
Fluorine: 18.99g/mol
Sodium: 22.98g/mol
Next, find the composition percentage of NaF
22.98 + 18.99 = 41.97
Fluorine is 18.99/41.97 =45.25%
Sodium is 100-45.25 = 54.75%
Ultimately we want to know about HF so find how much F is in 2.3g: 2.3 * 0.4525 = 1.041g
Find comp. percentage of HF
18.99+1.008 = 19.998; H/total F/total
Hydrogen 5.041%
Fluorine 94.959%
Laws of conservation of say we have 1.041g of fluorine in our HF. We know 1.041 is 94.959% of the mass of HF so do some simple math to find the remaining: 1.041/0.94959 = 1.096g
