Explanation:
reaction A is exothermic reaction as a substance is produced from two substances
and
reaction B is endothermic as two substances are formed from one complex structure
Answer:
The most state has the high volume is the gas state.
So here the answer is vaporization!!!!
Explanation:
The most state has the high volume is the gas state.
So here the answer is between vaporization and sublimation???
and when the sublimation is: the change of the material from the solid state to the gas state directly without pass to liquid state from the solid first then to the gas
and the vaporization is : The change of the material from the liquid state to the gas state by heating Ex: water vaporize at 100°
here, the answer is sublimation because the difference of volume which resulted from this process is more than the volume resulted from vaporization.

Answer:
<em>Scientists have observed that electromagnetic radiation has a dual "personality." Besides acting like waves, it acts like a stream of particles (called "photons") that have no mass. The photons with the highest energy correspond to the shortest wavelengths.</em>

Explanation:
235 U92 + 1n0 --> A + B + 3 1n0
when A = ;
(a) xenon-133
Mass number of B = 235 + 1 - 133 -3 = 100
Atomic number = 92 - 54 = 38
Element = Sr - Strontium
(b) barium-144
Mass number of B = 235 + 1 - 144 -3 = 89
Atomic number = 92 - 56 = 36
Element = Kr - Krypton
(c) cesium-143
Mass number of B = 235 + 1 - 143 -3 = 90
Atomic number = 92 - 55 = 37
Element = Rb - Rubidium
(d) tellurium-137
Mass number of B = 235 + 1 - 137 -3 = 96
Atomic number = 92 - 52 = 40
Element = Zr - Zirconium
(e) lanthanum-146
Mass number of B = 235 + 1 - 146 -3 = 87
Atomic number = 92 - 57 = 35
Element = Br - Bromine
