Question

Explain what property or law made the students realize their experiment was incorrect.

Answer 1

A group of students do an activity with baking soda and vinegar. The steps of the activity are listed below:
1. Pour 100 g vinegar into a flask.
2. Measure the temperature of the vinegar.
3. Add 10 g of baking soda to the flask.
4. Observe as the contents of the flask fizz (produce bubbles).
5. Measure the temperature of the contents in the flask and observe any change in temperature.

After the fizzing stops, the students determine that the liquid in the flask has a mass of 105 g. The students realize their experiment was incorrect.

Answer 2

Help please!!!!

Answer 3

When it fizzes, gas escapes while two substances were mixed, which explains the reason it has 105 g instead of 110 g at end.

Though I still don't see what makes experiment incorrect?

Answer 4

I cannot remember what property or law states that mass lost or gain while combining substances? Ring any bells to you?

Answer 5

You may want to post that question in chemistry section.

Answer 6

Thank you for answering and no, I can't think of anything that would lead to that.. this is so irritating.

Oh, chemistry? Thank you! c:
