Answer: Chyme
Explain: Chyme passes from the stomach to the small intestine. Further protein digestion takes place in the small intestine.
Wait, do you mind clarifying what you would like answered for the question?
Answer:
Carbon dioxide can be collected over water. Carbon dioxide is slightly soluble in water and denser than air, so another way to collect it is in a dry, upright gas jar.
Explanation:
Answer: The molecule 
is expected to have a dipole moment of zero.
Explanation:
The product of magnitude of the charge calculated in electrostatic units is called dipole moment.
Formula for dipole moment is as follows.
Dipole moment = Charge (in esu) 
distance (in cm)
Non-polar molecules have zero dipole moment.
For example, is a non-polar molecule so its dipole moment is zero.
is a polar molecule so it will have dipole moment.
is a polar molecule so it will have dipole moment.
has nitrogen atom as more electronegative than hydrogen atom. So, net dipole moment will be in the direction of nitrogen atom.
Thus, we can conclude that the molecule is expected to have a dipole moment of zero.
