1. because eventually the grass/food they are eating will loose its nutrients from eating it all the time and they need to migrate to find better food
2. the weather
3. their predators may migrate to the place they are and they need to migrate in order to have a better chance of survival
hope this helps these are just some reasons just ask if you need anymore
Binding energy, amount of energy required to separate a particle from a system of particles or to disperse all the particles of the system.
The question is: 10 g of carbonic acid H2CO3 are dissolved in 150 g of water. Determine the% m / m concentration of that solution?
Answer: The% m / m concentration of that solution is 6.66%.
Explanation:
Given: Mass of solute = 10 g
Mass of solvent = 150 g
Formula used to calculate the %m/m is as follows.
Substitute the values into above formula as follows.
Thus, we can conclude that the% m / m concentration of that solution is 6.66%.
Answer:
The order is
Quartz > Calcium > Ammonia > Chlorine
Explanation:
Among given compounds
Quartz is a covalent compound with extensive bondings and thus it will have highest melting point
Calcium is a metal so it will have strong metallic bonds thus will have high melting point, however less than quartz.
ammonia is a polar molecule with weak hydrogen bond as intermolecular interactions thus will have higher melting point than chlorine
chlorine is a non polar molecule with weak intermolecular london dispersion forces.
