Answer:
Option A, Tectonic plates above the currents move toward each other.
Option C, One plate will submerge beneath another plate.
Option D, A convergent boundary is formed at the site of the collision.
Explanation:
The convection currents are the ones responsible for the movement of the tectonic plates, thus shaping the Earth's appearance with their movement, as well with the structures created by the movement. If the convection currents move toward each other, than the tectonic plates are moving toward each other. That will cause collision between the continents, and convergent boundaries will be formed. If the collision is between two or more continental plates, than they will merge, and from the pressure mountain ranges will start to form, but if there an oceanic plate involved as well, than the oceanic plate will be subducting beneath the continental plate or plates.
Answer:
Freezing of water
Explanation:
When water becomes a solid it releases heat into its surroundings (warming it up).
Answer:
LOL YOUR PFP OMG SO FUNNY
When you cook the egg, you are changing the egg from a gooey liquid to a soft solid. So, liquid to solid is chemical change, so yeah? ...
Answer:reaction 2,5,6
Explanation:
First, we need to define what the enthalpy of formation is and what the enthalpy of reaction is____
<u>Formation Enthalpy</u>: It is the variation of the calorific energy in the reaction of ONE MOL of a compound starting from the elements.
<u>Reaction Enthalpy: </u>It s the variation of the calorific energy in the reaction of reactives, in this cases could be any quantity of mol
Then: We have six reactions:
1)CaCO3(g)→ CaO+ CO2(g)
2)Li(s)+12F2(g)→LiF(s)
3)CO(g)+12 O2(g)→ CO2(g)
4)2Li(s)+F2(g)→2LiF(s)
5)Li(s)+12F2(l)→LiF(s)
6)C(s,graphite)+ O2(g)→ CO2(g)
The enthalpy of reaction will be equal to reaction enthalpy when we produce one mol from elements
The answer is the reactions 2,5,6
