Answer:
C.
Fusion reactions require a lot of heat and pressure
Explanation:
nuclear fusion takes place only at extremely high temperatures. That's because a great deal of energy is needed to overcome the force of repulsion between the positively charged nuclei. ... A: Nuclear fusion doesn't occur naturally on Earth because it requires temperatures far higher than Earth temperatures.
Pretty sure it's 6 the atomic mass
Answer:
291.2L
Explanation:
Given parameters:
Number of moles of acetylene = 13moles
Unknown:
Volume of acetylene at STP = ?
Solution:
The problem can be solved by applying the equation that shows the relationship between the volume of gases at STP and their number of moles.
Volume of gas at STP = number of moles x 22.4
Input the variables and solve;
Volume of gas at STP = 13 x 22.4 = 291.2L
Answer:
Nuclear reactions involve a change in an atom's nucleus, usually producing a different element. Chemical reactions, on the other hand, involve only a rearrangement of electrons and do not involve changes in the nuclei.
