H2Se is the acid as it is donating H+ to H2O and forming SeH- (which is conjugate base).
H2O is the base since it’s receiving H+ from H2Se to form H3O+ (which is the conjugate acid)
Se is in the same group as O but is in different period which means Se has higher radius compred to O. this led to H-O bond being stronger than H-Se bond and H-Se bond which in turn makes it easier for H2Se to donate H to H2O
Answer:
The water cycle can be described as the cycle of different processes by which the water circulates between the ocean, atmosphere, and the land. It includes, precipitation (rain and snow), drainage, transpiration, and evaporation. The animals also play a crucial role in these cycle of processes. They release the water vapors into the atmosphere when they exhale, hence, letting the water molecules to again enter the cycle.Hence, the correct answer is
---- They release water vapor when they exhale'.

The reaction is spontaneous at a temperature of 7281.4 K
As the value of temperature rises, it is decreasing in accordance with the value of ΔG°, according to the value ofΔG° calculated. The value shifts from being more positive to being less positive. It ΔG°at a certain temperature.
It would appear that the value of would be negative, causing the reaction to occur on its own.
The calculation shown below can be used to determine the temperature at which the reaction starts spontaneously.
ΔG°= ΔH°-TΔS°
ΔG° now equals zero.
0 = 180.58 - T 24.8(1/1000)
T= 180.58/0.0248 K
T=7281.4 K
therefore, the reaction is spontaneous at a temperature of 7281.4 K

<span>The wick merely transports some of the liquid up to where vaporizes.It is not part of reaction but it does affect the reaction rate greatly,so it is a sort of catalyst in that time.if you wrap the wick in the aluminum it will block the transport the wax and it will wither go out less or brightly</span>
