Answer:
It releases a large amount of radiation
It takes place in the sun
It produces essentially all elements that are heavier than helium
Explanation:
Nuclear fusion refers to the reaction in which two nuclei of smaller atoms combine together to form a heavier nucleus. During this process, it releases a large amount of energy in the form of radiation. This process takes place extensively in the core of the sun that fuels the energy of the sun. It leads to the generation of essentially all of those elements that are comparatively heavier than the helium. This process also facilitates the conversion of hydrogen mass into energy.
Thus, the correct answers are mentioned above.
Magnesium oxide can be very bad for your health, and when we did an experiment with it in class it was white because it was so hot. It is very flammable.
Answer: A mole is a unit of measurement.
Explanation:
moles= mass/molar mass
for example moles=1000g/342.296 g/mol
moles=2.921 mol
Answer: 
Explanation: A single replacement reaction is one in which a more reactive element displaces a less reactive element from its salt solution.Thus zinc can easily lose electrons as compared to hydrogen and result in the formation of zinc chloride and hydrogen.
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
The atomic mass of Cu-63 and Cu-65 is 127.8 amu. Take the atomic weight of Cu- 63 and add Cu-65 to get the answers
