The image presents the chemical formula for calcium sulfate dihydrate, noted as CaSO₄•2H₂O(s). Below the formula, there is an expression for the standard entropy of formation, denoted as ΔS°f. This is followed by an empty box, suggesting either a placeholder for a value or a missing value. The units for entropy are given as Joules per mole per Kelvin (J mol⁻¹ K⁻¹).The image also contains graphical elements associated with the placeholder box: on the left side, a blue square containing the letter "i," indicating information or a tooltip might be available, and on the right side, an orange square with an exclamation mark, suggesting a warning or alert related to the missing value. **Calculate \( \Delta S^\circ_f \) for the following compounds in J mol\(^{-1}\) K\(^{-1}\):**---### Compound 1: \( \text{C}_2\text{H}_4(g) \)- **Your answer is incorrect.** **\( \Delta S^\circ_f = \) [Input Field] J mol\(^{-1}\) K\(^{-1}\)** ---### Compound 2: \( \text{HC}_2\text{H}_3\text{O}_2(l) \)- **Your answer is incorrect.** **\( \Delta S^\circ_f = \) [Input Field] J mol\(^{-1}\) K\(^{-1}\)** ---The image displays an online educational platform interface where users are prompted to calculate the standard entropy of formation for ethylene gas (\(\text{C}_2\text{H}_4\)) and acetic acid (\(\text{HC}_2\text{H}_3\text{O}_2\)), with their answers marked as incorrect. Users need to input their calculated values in the designated fields.

The balanced equation for the combustion of butane, CaH1o, is shown below. For your convenience, the molar mass of each substance is shown below their formulas (in purple). Use this information to make the requested calculation: 2 CAH10(g) + 13 02(g) -> 8 CO2(g) + 10 H20(1) 58.124 32 44.011 18.016 What mass of butane, in kg, will be needed to react fully with 250 L of oxygen gas?
What mass of CO2 (in Kg) does the combustion of a 12-gallon tank of gasoline release into the atmosphere? Assume the gasoline is pure octane (C8H18) and that it has density of 0.70 g/mL. You will need a balanced chemical equation for combustion of octane.
Soda ash (sodium carbonate) is widely used in the manufacture of glass. Prior to the environmental movement much of it was produced by the following reaction. CaCO3 + 2 NaCl → Na2CO3 + CaCl2 Unfortunately, the byproduct calcium chloride is of little use and was dumped into rivers, creating a pollution problem. As a result of the environmental movement, all of these plants closed. Assume that 125g of calcium carbonate (100.09 g/mol) and 125 g of sodium chloride (58.44 g/mol) are allowed to react. Determine how many grams of useful sodium carbonate (105.99 g/mol) will be produced. How many grams of useless calcium chloride (110.98 g/mol) will be produced? You should also determine how many grams of excess reactants are left (indicate which one is the limiting reactant)
Dimethyl ether, a useful organic solvent, is prepared in two steps. In the first step, carbon dioxide and hydrogen react to form methanol and water: CO₂(g) + 3 H₂(g) CH₂OH(1) + H₂O(1) In the second step, methanol reacts to form dimethyl ether and water: 2 CH₂OH(1)→ CH₂OCH3(g) + H₂O(1) Calculate the net change in enthalpy for the formation of one mole of dimethyl ether from carbon dioxide and hydrogen from these reactions.
