Answer:
0.034 mol (4dp)
Explanation:
Use the formula n = m/M where n= number of moles, m=mass in grams and M=molar mass in g/mol.
Therefore to find how many moles, divide the mass in grams (2) by the molar mass of sodium chloride which is 22.99+35.45
Hey there!!
A lawn mower works by converting chemical energy (energy stored in the gas) to mechanical energy.
Hope this helps you and have a great day!!!! I wish you the best of luck (:
A MOUNTAIN RANGE is a landform with high elevation and a more or less level surface
Answer:
Explanation:
The expression for density is:
M is molar mass of Calcium = 40.078 g/mol
For cubic closest packed structure , Z= 4
is the density
Radius = 197 pm = 
Also, for fcc, 
Thus,
Answer:
Uranium-233- fission
Plutonium-239- fission
Plutonium-241- fission
Hydrogen-3 fusion
Hydrogen-1 fusion
Helium-3 fusion
Explanation:
In nuclear fission, heavy nuclear disintegrate into smaller nuclei when bombarded with particles such as neutrons. Fission reaction is common among nuclei having a high atomic number such as plutonium and uranium.
Fusion occurs between two light nuclei such as hydrogen or helium. It involves the combination of two lighter elements to give a heavier element with the release of tremendous amount of energy.
