When an atom undergoes radioactive decay which is where it spontaneously emit matter and energy from its nucleus, the part of the atom that is affected is the nucleus as it is known to breakdown due to the instability it possesses because of the neutron to proton ratio. This matter and energy is released as the atom hopes to attain stability- transmutes from one element to the next, and will continue emission until it does attain stability.
Answer: Seastars prey on mussels and shellfish which would otherwise have no other natural predators. Herbivorous fish like the butterflyfish pictured to the left prey on marine algae. Without this crucial predator-prey balance, the algae would over-grow, which would then kill coral, as they compete for the same resources.
The change in internal energy of the combustion of biphenyl in Kj is calculated as follows
=heat capacity of bomb calorimeter x delta T where delta T is change in temperature
delta T = 29.4 -25.8= 3.6 c
= 5.86 kj/c x 3.6 c = 21.096 kj
Explanation:
Vu de chez nous, sur terre, la lune et le soleil ont la même taille et semblent bien plus petits que la terre. ... À quelle distance se trouve la terre du soleil?
