You have 100 mL of 0.250M KMnO4. If you transfer 12.9mL of this solution to an Erlenmeyer flask and add 75.0mL of water, what is the concentration of the solution in
the Erlenmeyer flask? What is the concentration of the solution in the original bottle?

b) nuclear ive learned that in a pedtrodic table

answer: mole of the gas

answer: mole of the gasexplanation:

ok whats the question if not i cannot you i need question and need a thing to answer

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
