but.......you havent attached a picture?
Answer:
reaction rates increase because reactants move faster, collide more often, and produce more collisions with the required energy of activation.
Explanation:
<em>A</em><em>t</em><em> </em><em>h</em><em>i</em><em>g</em><em>h</em><em>e</em><em>r</em><em> </em><em>t</em><em>e</em><em>m</em><em>p</em><em>e</em><em>r</em><em>a</em><em>t</em><em>u</em><em>r</em><em>e</em><em>s</em><em>,</em><em> </em>the reactant atoms gain high kinetic energy which decreases the intermolecular forces of attraction between these atoms/molecules.
Hence the rate of collision is very high which decreases the activation energy and products are formed with in a short period of time.
Yeah, it increases the surface tension !!!
Iron (II) oxide is composed of iron with an oxidation number of +2 (shown by the II after iron) and an oxygen that has an oxidation number of -2 (oxygen almost always has an oxidation state of -2). Since the anion and cation both have a charge of +or- 2, they bond with each other with a 1 to 1 ratio and the formula should be FeO
I hope this helps. Let me know if anything is unclear.
