In the following redox reaction which is the oxidizing agent and which is the reducing agent? alcl3 + na nacl + al

What is the percentage of hydrogen in c2h4

Question 3(multiple choice worth 4 points) (04.04 lc) what does it mean when an element is reduced? it empties a valance shell, reducing its atomic radius. it gains electrons, reducing its overall charge. it increases electronegativity, reducing its ability to bond. it loses electrons, reducing its electron number.
