Answer:
Lithium Chloride would be the best one
Sodium Hydroxide would be the second best
Explanation:
The answer is B. Nitrogen and sulfur oxides combine with rain percipitation to form sulfuric acid rain.
The empirical formula is CH2O bc you divide the percent and the mass of the element, Carbon 40/12.01=3.33, Hydrogen 6.7/1.01=6.63, Oxygen 53.3/16.00=3.33, then divide the lowest number which is 3.33 to all Carbon 3.33/3.33=1, Hydrogen 6.63/3.33=1.99 but rounds to 2, Oxygen 3.33/3.33=1
Answer:
The entropy change for the vaporization of 18 grams of a hydrocarbon at its boiling point is 12.87 J/K.
Explanation:
Mass of hydrocarbon = 18 g
Molar mass of hydrocarbon = 114 g/mol
Moles of hydrocarbons =
The enthalpy of vaporization of hydrocarbon =
Heat required to heat 0.1579 moles of hydrocarbon = Q
Q = 4.263 kJ = 4,263 J ( 1 kJ = 1000 J)
Boiling point of hydrocarbon = T = 58.2°C = 58.2 + 273 K = 331.2 K
Entropy change for the vaporization of 18 g of a hydrocarbon:
The entropy change for the vaporization of 18 grams of a hydrocarbon at its boiling point is 12.87 J/K.
If there is any unused Chemicals left in the container it should be properly disposed and chemicals taken out of the original container should not be poured back into the container because it can be <span>contaminated</span>
