<span>Scientists with NASA's Cassini mission have spotted "Pac-Man" images on moons of Saturn, Mimas & Tethys. The image in Mimas was seen in the year 2010, while in Tethys in the year 2011. The pattern appears in thermal data taken by Cassini's infrared spectrometer, with the warmer areas making up the Pac-Man shape. </span>
Answer:
D
Explanation:
Breaking bonds absorbs (Requires) energy. Forming bonds releases it. It's kinda backwards but that's how it works. :)
<span>1 drop is approximately 0.05mL. Since 0.500L of 0.550M NH4Cl contains 0.275mol of substance (calculated by using c=n/V formula), equal amount of substance of NH3 is needed to neutralize this solution (since pH of 7 is neutral solution). Thus, we need 0.0275L of NH3, i.e. around 550 drops.</span>
Answer: Option (D) is the correct answer.
Explanation:
In fusion reaction, two small nuclei combine together to result in the formation of a large nuclei.
Whereas in fission reaction, large nuclei dissociates into two or more small nuclei.
Nuclear fusion releases more energy as compared to nuclear fission.
For example, two hydrogen nuceli fuse together and result in the formation of helium atom along with release of energy.
The answer should be neutralization
