The specific heat of silver is 0.24 J/g°C. If 15.4 g of silver absorb 332 J heat, how much will the temperature of the silver increase?

q = mass Ag x specific heat Ag x delta T.

Substitute and solve for dT

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.

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.
