- Separated by an actual physical barrier
<span>- Geographic isolation can be overcome in some circumstances but the majority of the population will be isolated and therefore will diverge into different species

did this help if it did leave a thanks
Answer:
1. denser
2. subduction
3. divergence
4. hot spots
5. earthquakes
6. An underwater hot-spot volcano occasionally erupts, and the lava solidifies into an island. However, the plate that lies above the hot spot continues to move due to slab pull and ridge push, so the stationary volcano will be in a different location when it erupts again. This forms a new island, and the process may continue.
Answer:
3.384364 time 10^24 atoms
Explanation:
multiply by avogadro's number
Answer:
Q = -897 kJ/mol
Explanation:
From the given information:
The heat released Q = -65.9 kJ
To start with the molar mass of
= 2 × (molar mass of H) + 2 × (molar mass of O)
= (2 × 1.008) + (2 × 16.0 )
= 34.016 g/mol
However, given that:
mass of
2.50 g
The number of moles of
= ![\dfrac{mass}{molar \ mass}](https://tex.z-dn.net/?f=%5Cdfrac%7Bmass%7D%7Bmolar%20%5C%20mass%7D)
![= \dfrac{2.5}{34.016}](https://tex.z-dn.net/?f=%3D%20%5Cdfrac%7B2.5%7D%7B34.016%7D)
![= 7.349 \times 10^{-2} \ mol](https://tex.z-dn.net/?f=%3D%207.349%20%5Ctimes%2010%5E%7B-2%7D%20%5C%20mol)
Finally; Using the formula:
![\Delta H = \dfrac{Q}{number \ of \ moles}\\ \\ Q = \dfrac{-65.9 \ kJ}{7.349 \times 10^{-2} \ mol}](https://tex.z-dn.net/?f=%5CDelta%20H%20%3D%20%5Cdfrac%7BQ%7D%7Bnumber%20%5C%20of%20%5C%20moles%7D%5C%5C%20%5C%5C%20Q%20%3D%20%5Cdfrac%7B-65.9%20%5C%20kJ%7D%7B7.349%20%5Ctimes%2010%5E%7B-2%7D%20%5C%20mol%7D)
Q = -897 kJ/mol
