Definitely Calcium Chloride.
All the others are covalent.
Answer:
Alkenes have substituents, hydrogen atoms attached to the carbons in the double bonds. The more substituents the alkenes have, the more stable they are. Thus, a tetra substituted alkene is more stable than a tri-substituted alkene, which is more stable than a di-substituted alkene or an unsubstituted one.
Answer: The change in internal energy of the gas is +408 J
Explanation:
According to first law of thermodynamics:
=Change in internal energy
q = heat absorbed or released
w = work done or by the system
w = work done on the system=
As volume is constant , = 0 and w = 0.
q = +408J {Heat absorbed by the system is positive}
Thus the change in internal energy of the gas is +408 J
Put a picture we can’t see the arrow
Answer:
concentration = mol/volume = 4/2 = 2M
