You have to find an equation that would relate the two motions of the locomotives. When they meet at a certain point after being 8.5 km apart initially, then that means that their individual distances traveled is equal to 8.5 The solution is as follows:
Distance = speed*time
Total distace = 8.5 = 155t + 155t
Solving for t,
t = 0.027 hour or 98.71 seconds
Answer:
when they have 8 valence electrons
The correct answer is - It is the part of the ocean where new crusts are formed.
The place marked with A on the map is the place in the ocean where the new crust is formed. That is a place where there's a divergent plate boundary, or rather a place where the tectonic plates are moving away from one another. The gap and cracks left between them are easy target for the magma from the mantle to penetrate towards the surface. As the magma reaches the ocean floor it starts to cool off very quickly, creating new crust, and slowly making a very large underwater mountain range known as mid-ocean ridge.
These are the characteristics that apply:
- In a solution taste sour: which is consequence of the H+ concentration.
- Corrode metals: the H+ ion reacts with the metal producing a salt and water
-Produce hydronium ion in solution: as per the Bronsted - Lowry definition an acid is a substance that donates a proton, H+. This proton will react with H2O to form H3O+ (hydronium), as per this scheme:
HA + H2O --> A(-) + H3O(+)
