The answer is D. Rubber. Because A, B, and C are metal materials that will insulate heat without any gaps. Hope this helped!
Electrons absorb energy, as they absorb energy they go from ground state to excited state and to return to ground state electrons release energy in the form of photons producing that color.
Answer:
The forward reaction will be favored.
Explanation:
The reaction is:
As per equation (equilibrium equation), there are two moles of gaseous molecules on product side and three moles of reactant side.
a) If we increase pressure, the volume will decrease.
b) Due to decrease in volume, the moles per unit volume will increase.
c) In order to attain equilibrium again, the system will shift in the direction where it can nullify this effect [Le Chatelier's principle]
d) This can be done, if system moves in the direction where number of moles of gaseous molecules are less, which is product side.
e) Thus forward reaction will be favored.
All of the above.
The properties of water are:
1) polar molecules
2) regulates temperature
3) universal solvent
4) high surface tension
5) can exist in all three stages of matter
