A. It absorbs energy.
reactants are located on the left side of the equation, meaning energy among with other reactants were needed to get the reaction going, so it absorbed energy, which is also the endothermic process. The opposite of that would be having energy on the right side with the products which means that the reaction would've released energy which is the exothermic process. Hope this helps!
The pH scale is used to measure how acidic or alkaline something is.
Hope that helped you!

Answer:
Sphere
Explanation:
The shape of the s-sublevel is spherical in shape.
This sublevel has an azimuthal quantum number of 0 and it is spherical in shape;
- p - sublevel has a dumb-bell shape
- d - sublevel has double dumb - bell shape
- f - sublevel has a complex shape
That they both will be the same average kinetic energy
30% should be the percentage of oxygen if the total mass of fe2o3 is 160.
