The energy that is released in the hydrogen fusion reaction comes from the difference in mass between the 4 hydrogen H nuclei and single helium He nucleus
The answer is: The difference in mass between the four hydrogen nuclei and single helium nucleus
D - it is the number of protons in the nucleus
First we will calculate the number of moles of Iron:
, where n is the number of moles, m is the mass of iron in the reaction and M is the Atomic weight.
moles of Iron.
The same number of moles of Oxygen will take part in the reaction.
So
where 32 is the Atomical Weight of Oxygen (16 x 2).
=>
g
<h2>The Answer is option d "polymers"</h2>
Explanation:
- Polymers are also categorized as plastics.
- Polymers are usually soft and ductile that is it can be drawn into wires.
- Polymers have low heat capacity or heat conductivity that is the extent to which a polymer acts as an insulator towards the temperature.
- Polymers can be opaque ( not be seen through), translucent or transparent (to be seen clearly through).
- Hence the right answer is option d "polymers".
We would most likely use a model for an atom, which shows the nucleus, particles, and the electrons + orbitals
