Solution -
Electrons carry negative charge while nucleus carries positive charge due to the presence of positively charged proton ions and neutral ions (which has no charge). All the electrons are attracted towards the nucleus due to its positive charge. The orbit on which an electron revolves around a nucleus has higher energy level as compared to the energy levels located in between the space of electron and nucleus.
While moving from a high energy orbital to a low energy level orbital, an electron releases some energy. Hence, in order to move closer to home, electron needs to push itself toward the nucleus by releasing energy
Hence, the given option is B

Answer:
45 g of the solid Tris will be dissolved in 2.5 liters of water.
Explanation:
Recall that:
<em>Number of moles = molarity x volume</em>
Hence, number of moles of Tris present in 2.5 liters, 150 mM solution:
= 150/1000 x 2.5 = 0.375 moles
Also, recall that:
<em>No of moles of substance = mass/molar mass.</em>
Hence, mass of 0.375 moles substance:
= no of moles of the substance x molar mass of the substance.
= 0.375 x 120 = 45 g.
Therefore, in order to prepare 2.5 liters, 150 mM of an aqueous solution of Tris, 45 g of the solid Tris will be dissolved in 2.5 liters of water.
Answer:
D. Celsius
Explanation:
Temperatures up to 37.3 and down to 36.7 are considered to be within the normal body temperature scale in Celsius.
A. True
However, this is not necessarily the only factor that makes this true.
