Answer:
the answer to this question is hydrogen gas
<u>Answer:</u>
For 1: The correct answer is option D.
For 2: The correct answer is option A.
<u>Explanation:</u>
There are two types of molecules which can be categorized on the basis of electronegativity difference:
Polar molecules: In these type of molecules, the two atoms combining must be different so that a dipole can be created and for that the electronegativity of two atoms combining must not be same. The negative dipole of charge is created on the electronegative atom and positive dipole or charge is created on the electropositive atom.
Hence, the correct answer is option D.
Non-polar molecules are defined as the molecules which do not have any dipole and is formed when two atoms of same element combine together which have the same electronegativity. The electronegativity difference of these molecules is 0.
Hence, the correct answer is A.
Answer:
A. Calcium chloride (CaCI2)
Polymer scientists have been trying to mimic this behavior by creating so called smart polymers. ... One of the most important classes of stimuli-responsive polymers used for controlled drug delivery is crosslinked polymer networks, e.g., hydrogels and microgels.
Hopefully this helps if not I’ll try rewriting it
