Answer:
Two reagents that can be used to distinguish between ethane and ethyne are Tollens' reagent and ammoniacal CuCl solution.
Na3 = 23*3 = 69
P = 31
O4 = 16*4 =64
69+ 31+ 64 = 164g/mol
0.75mol = 0.75 * 164 = 123 g
First to answer
Answer:
D: Protons that make up a nitrogen atom stays together in the nucleus
This is because a electromagnetic force is responsible for atomic structure, chemical reactions, the attractive and repulsive forces associated with electrical charge and magnetism, and other electromagnetic phenomena.

Answer:
See explanation
Explanation:
The heat capacity of a substance is determined by the chemical composition of the substance and its mass.
Now, if substances have equal masses, the substance with the lesser heat capacity undergoes the greater temperature change.
Hence, among the substances, the particular one with the lowest heat capacity is expected to undergo the greatest temperature change.
