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
Answer:
Explanation:
Food wrappers and aluminium wrappers are widely use for packing various eatable items.
For example, in our homes our mother wraps our food for lunch in aluminium foil.
As it helps in keeping the food warm for hours.
Thus, we can conclude that out of the given options, a packaging waste is the garbage collector collecting.
The answer should be B - Nitrogen Dioxide.
Answer:
The mass percent of copper as element is the same.
Explanation:
First of all we need the reaction that is presented below:
→ 
The mass percent of copper (Cu) as element is the same because of during the reaction the element only transform its nature from copper carbonate (
) to copper oxide (
), the latter is a solid and will remain in the system.
On the other hand, you will note that the global percentage mass will be small because of the reaction produce (
) that is a gas and this one will escape for the system.
Have a great day!
