A stars life cycle is determined by its mass it depends on the path so if it’s a large or small there life cycle
Answer: C. Al (aluminum)
Explanation: it has 3 valence electrons :)
Because the sub gives us heat when the moon blocks it it also blocks the path of heat
Answer:
BaF2(s) ------> Ba2 (aq) + 2F- (aq)
Explanation:
Entropy refers to the degree of disorderliness in a system. Processes that lead to greater disorderliness in a system are said to increase the entropy of the system or lead to a positive value of ΔS.
If we consider the process, BaF2(s) ------> Ba2 (aq) + 2F- (aq), we will notice that ions were produced in solution thereby increasing the disorderliness of the system.
Explanation:
The molecules in the solute and solvent are only able to make dispersion forces with each other (as they aren't both polar). This only releases very little energy. Therefore overall, more energy is required than released and hence they won't mix.
