NaOCI to be used in an experiment is available as a 5.5% w/v solution. If the reaction requires 250 mg NaOCI, how much of the 5.5% solution do you need to add

What are the similarities of physical and chemical change ?

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.

Achemical reaction is done in the setup shown, resulting in a change of mass. what will happen if the same reaction is done in a sealed container that is placed on the electronic balance?
