If 1.0dm3 of gas X diffuses through a porous plug in 60seconds while the same volume of hydrogen diffuses in 15seconds under the same condition . Calculate the Relative Molecular Mass

since electrons are negative the answer is neagtaive

it is a solid

explanation:

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.
