The earths rotation tilts around 23.5 degrees on its pole axis, relative to the plane of earths solar system orbit around the sun. as earth orbits the sun, this creates a 47 degree solar altitude angle
Evaporation occurs when water molecules at the surface of a pool have enough kinetic energy that the attractive forces holding them to the liquid can be overcome
Answer:
D. 5.0
Explanation:
Step 1: Write the balanced equation at equilibrium
2 NO₂(g) ⇄ N₂O₄(g)
Step 2: Calculate the concentration equilibrium constant
The concentration equilibrium constant (Kc) is equal to the product of the concentrations of the products raised to their stoichiometric coefficients divided by the product of the concentrations of the reactants raised to their stoichiometric coefficients.
Kc = [N₂O₄]/[NO₂]² = 0.2 / 0.2² = 5
Answer:
C since however many times you repeat an experiment, it should give the exact same results or it wouldn't be accurate enough. ex if you measure a liquid to be 77ml in USA, it should give the same when measured in Germany, same with repeating experiments.
Answer is: t<span>he greater size of the naphthalene molecule.
Naphthalene (C</span>₁₀H₈) has melting point 80°C and phenol (C₆H₅OH) has melting point of 40,5°C.
Naphthalene has greater molecular mass (128,17 g/mol) and greater size than phenol (<span>94,11 g/mol).
</span><span>The melting point of solid is defined as the temperature at which the solid exists in equilibrium with its liquid under an external pressure of one atmosphere.</span>
