Explain the relationship between the actual free energy change, the reaction quotient Q and the direction in which a reaction proceeds to reach equilibrium
A mixture of CS2 (g) and excess O2 (g) is placed in a 10.0 L reaction vessel at 100.0 degrees C and the pressure of 3.00 atm, A spark causes the CS2 to ignite, burning it completely, according to the equation:
the corresponding sound. If you are 480.0 m from the explosion and the speed of sound is 340 m/s, calculate the distance traveled by the light during the brief delay required for the sound to reach
A solution is prepared from 0.95 grams of H3PO4 ,(Phosphoric acid) and 1.15 grams of HClO4 (perchloric acid) in 150 mili litres of solution then determine how many milliliters of 0.425 M sodium hydroxide( NaOH) is needed.
Describe what will happen to the length of the rubber band when the hair dryer is turned on, and explain the observed behavior.
The half-cell is a chamber in the voltaic cell where one half-cell is the site of the oxidation reaction and the other half-cell is the site of the reduction reaction.
calculate the percent of radioactive parent atoms remaining 2 hours after medicine is administered. the percent is the
At 25 degree C the density of a 50% by mass ethanol-water solution is 0.914g per cubic cm. Given the partial molar volume of water in the solution is 17.4 cubic cm per mol, calculate the partial molar volume of the ethanol.
