50 points! When a sodium thiosulfate solution (Na2S2O3(aq)) is added to hydrochloric acid, sulfur is formed.

1. What would you observe during the reaction? How could you set up the experiment to measure the reaction time for a given combination of thiosulfate and acid solutions?

2. What other products are formed?

3. Apart from heating it, how else could you speed up the reaction? How would this work?

1. Insoluble yellow solid sulfur forms and gets deposited at the bottom. to setup the experiment draw a cross on a white paper and place beaker on top of it. take known volumes of sodium thiosulfate and hydrochloric acid in a beaker and mix it. At the same time start stop watch. measure time taken for the cross to disappear.

2. Sodium chloride, sulfurdioxide and water

3. increase concentration of acid

the food using pesticides in the future will harm you by giving you diseases like cancer or something since they have things that we should not eat in it like chemicals or pesticides. that is why organic food is more expensive because they take the time to make it right and healthy for you to eat.

explanation:

i would say b

explanation:

but i think i would need more information than that
