Just remember how many electrons can each sublevel hold.
S=2
P=6
D=10
Since we have 10 for atomic number, we can assume we have 10 electrons
1S2
2S2
2P6
The rest have zero because we already have 10 (2+2+6=10)
If the temperature rises in a reaction. Exothermic is if it loses heat.
Have a nice day, brainliest would be fantastic.
B. Biomass
(I guess so cause other ones are already being used)
The answer is to increase the surface area of the solute.
You see it dissolves faster because there is a lot more water touching it when it is has a higher surface area.This can be achieved by crushing
