The correct answer is the second option. <span>Baking soda fizzing in vinegar is an example of a chemical change. This example is a chemical reaction which undergoes a chemical change since new substances are being formed the fizzing of the system represent that gas is being produced by the reaction.</span>
Explanation:
He weighed silver, dissolved it in acid, and then recovered all the original silver by reacting the solution with copper. He also showed, by using iron to recover the copper, that this displacement of one metal from its salt by using a second metal was not because of transmutation, as many had held.
1. Acetic acid (Ethanoic acid) is a colorless liquid.
2. Sodium Bicarbonate is an odorless, crystalline powder.
3. Carbon dioxide is a colorless gas.
4. Dihydrogen monoxide is colorless and odorless gas.
5. Sodium acetate is very soluble in water.
6. Calcium chloride has an exothermic reaction when dissolved in water.
7. Calcium carbonate is also an odorless powder.

Hope this helps! (:
Answer:
60 g/100 g water
Explanation:
Find 5 °C on the horizontal axis.
Draw a line vertically from that point until you reach the solubility curve for CaCl₂.
Then draw a horizontal line from there to the vertical axis.
The solubility of CaCl₂ is 60 g/100 g water.
