Please answer 11 to 13 to receive 10 points. Please read the bullet points to under the questions. And check the molecular formula image.

11 yes

12 H2O( water molecules)

13 3H2O( water molecules)

Explanation:

Sry, my phone's a potato, so I didn't read it properly, so I'm not sure about the question 11.

11-yes, they stay together, but they release 3 molecules of OH an H.

12- here it talks about what will happen with OH and H: they will be H2O (water molecules).

13- and here we end it with the informations that we got: 3 fatty acids+ glycerol---> fat+ 3H2O( the 3 H and 3 OH)

the answer is na (sodium)
