Q is determined to be 12.38. The Nernst equation is expressed as Ecell = E°cell - (2.303RT/nF) log Q, where Q represents the reaction quotient. The reaction quotient Q is calculated by taking the product of the products' concentrations divided by the product of the reactants' concentrations. For an electrochemical cell, Q is the concentration ratio of the solution at the anode compared to that at the cathode. Consequently, Q = [anode]/[cathode], specifically Q = 0.052/0.0042, arriving at a value of Q = 12.38.
I predict that there will be an increase in the seconds recorded in the time column. This is because, as more water is mixed with sodium thiosulfate, its concentration diminishes in each flask. Additionally, a lower concentration results in a slower reaction rate since fewer molecules of sodium thiosulfate means there are less frequent collisions with sulfuric acid. With fewer collisions occurring in the reaction, it takes a longer time for the reaction to complete, leading to increased time when sodium thiosulfate is diluted.
Explanation:
I can confirm that this explanation is accurate.
Answer:
The vehicle travels 660 feet
Explanation:
Initially, convert the speed into Feet per second
The car's speed is 90 mi/hr
1 mi = 5280 ft
For 90 miles, we calculate 90 x 5280 = 475,200 feet
1 hour = 60 minutes
1 minute = 60 seconds
Therefore,
1 hour = 60 x 60 seconds = 3600 seconds
Speed is defined as the distance covered by an object over time. The speed formula is:
... given
Speed = 132 ft/sec
Thus, time = 5 seconds
Distance = 660 feet
