Answer:
I would say a cooled
Explanation:
because yeah it's going to be cold when it travels from Antarctica but then it's going on towards Africa and yeah the water is going to get warmth but it's going to cool the land of Antarctica because it's so dry and hot and humid but the water is going to be more warmed because Antarctica the water is freezing so you're trying to ask the temperature of the water it'd be more warm if you're trying to ask kind of like the temperature of the land it would be cooled
You can tell that the atom is in the excited state because:
- Electron configuration should follow the 2-8-8-2 rule, meaning that the inner shell should be filled before the next shell can start holding electrons.
- Instead of the atom's electron configuration being in the ground state at 2-8-8-1, electrons from the second shell have jumped to the third.
Answer:
The Answer Is Chemical Change :)
The mantle has a mass of around
that is around 68.4% of earth's mass.
So to calculate moles we need to first find out the mass of oxygen and silicon present in mantle. It is given that oxygen is 44.8% by mass in mantle and 21.5% by mass in mantle, therefore to calculate its mass, we need to use 
Now, to calculate mass percentage of oxygen


Similarly the mass of silicon can be calculated

Now, the moles of any substance is calculated by


where, mass of oxygen in kilograms is 
So,
Similarly 

Now, to calculate mole ratio we need to divide every moles to the lowest calculated mole that is the moles of Si and round it off to the nearest whole number.
