A salt has a solubility in water of 2.5 g/L at 25 °C Suppose you mixed 10.0 g of this salt with 3.0 L of water in a beaker and allowed the salt to dissolve. The temperature of the solution was kept at 25 °C. Would there be any solid left in the beaker after the salt has dissolved? Select one: O Yes, there would be some solid would be left in the beaker. O No, there would not be any solid left in the beaker. O Not enough information is provided to answer this question

• Consider the following reaction: 3 Fe(s) + 4 H₂O(g) ↔ Fe3O4(s) + 4 H₂(g) At 900 °C, Kc for the reaction is 5.1. If 0.050 mol H₂O(g) and 0.100 mole Fe(s) are placed in a 1.0 L container at 900 °C, how many grams of Fe₂O4 are present when equilibrium is established

While ethanol (CH,CH,OH) is produced naturally by fermentation, e.g. in beer- and wine-making, industrially it is synthesized by reacting ethylene (CH,CH,) with water vapor at elevated temperatures. A chemical engineer studying this reaction fills a 75 L tank with 10. mol of ethylene gas and 5.4 mol of water vapor. When the mixture has come to equilibrium he determines that it contains 6.8 mol of ethylene gas and 2.2 mol of water vapor. The engineer then adds another 1.4 mol of water, and allows the mixture to come to equilibrium again. Calculate the moles of ethanol after equilibrium is reached the second time. Round your answer to 2 significant digits. |mol x10 O

Consider the combustion of methane (as represented by the following equation). This is the reaction that occurs for a Bunsen burner, which is a source of heat for chemical reactions in the laboratory.  CH4(g) + 2O2(g)   CO2(g) + 2H2O(g)For the system at chemical equilibrium, which of the following explains what happens if the temperature is raised? Group of answer choices The equilibrium position is shifted to the left and the value for K decreases. The equilibrium position is shifted to the right and the value for K decreases. The equilibrium position is shifted to the left and the value for K increases. The equilibrium position is shifted to the right and the value for K increases. The equilibrium position is shifted but the value for K stays constant.
