What is the reaction equation for this: Place 0.75 g of 3-nitroacetophenone, 10 mL of absolute ethanol, and a magnetic stir bar in an Ts 19, 50 mL round bottom flask (rbf). Equip the flask with a condenser, begin stirring, then warm the solution in an oil bath heated to 90 °C until a solution is obtained. Cool the solution to room temperature then remove the condenser: a fine suspension of solid may form. Stir the suspension at room temperature while adding in 0.28 g of sodium borohydride. Stir then add 7.5 mL of water. Remove the flask from the heat source, cautiously add 0.5 mL (~10 drops) 3M HCl (aq) dropwise with stirring, and cool the reaction solution for 10 minutes in an ice-water bath to produce a suspension of the product.
To identify a diatomic gas (X2), a researcher carried out the following experiement. She weighed an empty 4.2L bulb, then filled it with the gas at 1.30atm and 23.0C and weighted it again. The difference in mass was 6.3 g. Identify the gas
