elixir [45]

Answer:

animals unlike us adapt faster to heat/cool weather or water

Explanation: Let's use fish as an example because that's the main water pet, so when you get a new fish and you have to put it in the water for about let's say 15 minutes. It's so it can adapt to the water. Water for us needs to be hot enough for us to actually feel the heat so therefore animals can adapt not only faster to heat but to cool air/water a lot faster than we can. I don't know if this helps or makes sense but it's what I know and have seen :P

Are solar and lunar eclipses processed by the movements of the Earth and moon?
Inga [223]

Explanation:

As the Earth rotates on its axis and revolves around the Sun, several different effects are produced.

Consider the following reaction at constant pressure. Use the information provided below to determine the value of ΔS at 473 K.
Elis [28]

Answer:

The reaction will be spontaneous

Explanation:

To determine if the reaction will be spontaneous or not at this temperature, we need to calculate the Gibbs's energy using the following formula:

\Delta G= \Delta H - T * \Delta S

<u>If the Gibbs's energy is negative, the reaction will be spontaneous, but if it's positive it will not.</u>

Calculating the \Delta G= -1267 - 473 K* \Delta S :

\Delta G= -1267 - 473 K* \Delta S

Now, other factor we need to determine is the sign of the S variation. When talking about gases, the more moles you have in your system the more enthropic it is.

In this reaction you go from 7 moles to 8 moles of gas, so you can say that you are going from one enthropy to another higher than the first one. This results in: \Delta S>0[/tex}Back to this expression: [tex]\Delta G= -1267 - 473 K* \Delta S

If the variation of S is positive, the Gibbs's energy will be negative always and the reaction will be spontaneous.
