Read the following hypothesis about why a chicken bone becomes bendy after being soaked in vinegar:

The bone can bend because the acid in the vinegar has removed the calcium that made it hard.
What evidence would support this hypothesis?
A. observing that a bone placed in a freezer becomes more rigid
B. observing that a bone placed in a beaker of acid becomes bendy
C. observing that a bone placed in a beaker of water becomes bendy
D. observing that a bone placed in a mixture of baking soda and water becomes more rigid

B. observing that a bone placed in a beaker of acid becomes bendy

Explanation:

The hypothesis suggests that when chicken bones are placed in vinegar, they become bendy due to the loss of calcium in their bones.

Calcium is identified as the ossifying material that strengthens the bone. When the acid that makes up the vinegar comes in contact with it, calcium is removed from the bone.

Now we know that calcium has capabilities of reacting with acids.

This suggests that if we also place the bone in an acid, they will bend due to reaction of calcium in the bones with the acid.

the only liquid elements at standard temperature and pressure are bromine (br) and mercury (hg). although, elements caesium (cs), rubidium (rb), francium (fr) and gallium (ga) become liquid at or just above room temperature.
