To determine the pOH assuming water is the universal solvent take the value of 10 ^ -14 and then divide it by the hydronium concentration and then take the negative logarithm of the final answer that is the solution to the hydroxide ion concentration in the solution.
Explanation:
Endothermic animals are also known as warm-blooded, they have the capacity to regulate their body temperature independent of the environment. They have mechanisms to compensate if heat loss exceeds heat generation (shivers) Or if heat generation exceeds the heat loss (panting, sweating).
On the other hand, ectothermal animals are known as cold blooded organisms and depend on external sources, like sunlight, to regulate their body temperature, reptiles are ectothermals.
To determine if the animal of interest is endo or ectothermal you’ll have to consider that is a reptile, you’ll also observe that it consumes less food and finally it’ll have more difficulties to adapt to sudden temperature changes.
I hope you find this information useful and interesting! Good luck!
Answer:
2.49*10⁻¹² mol
Explanation:
Use Avogadro's Number for this equation (6.022*10²³). Divide Avogrado's by the number of atoms you have to find moles. You are answer should be 2.49*10⁻¹² mol.
Answer: 0.0007 moles of 
is released when temperature is raised.
Explanation:
To calculate the number of moles, we use the ideal gas equation, which is:
where,
P = pressure of the gas = 1.01 bar
V = Volume of the gas = 1L
R = Gas constant = 
- Number of moles when T = 20° C
Temperature of the gas = 20° C = (273 + 20)K = 293K
Putting values in above equation, we get:
- Number of moles when T = 25° C
Temperature of the gas = 25° C = (273 + 25)K = 298K
Putting values in above equation, we get:
- Number of moles released =
Hence, 0.0007 moles of is released when temperature is raised from 20° C to 25° C
