The compound AX2 decomposes according to the equation, 2 AX2(g) => 2 AX(g) + X2(g). In one experiment, [AX2] was measured at various times, and these data recorded: Time (s) [ AX2] mol/L 0 0.0500 2.0 0.0448 6.0 0.0300 8.0 0.0249 10.0 0.0209 20.0 0.0088 What is the average rate from 6.0 to 10.0 seconds in mol / L s? Use 3 significant figures. [don't include units in your answer; if you want to use scientific notation, use the E format. e.g., 0.0011 is 1.1E-3
The pH of 0.5 M formic acic, HCOOH, is 2.02. Calculate the difference in pH when 6.42 g of HCOONa is added to 390.9 mL of 0.50 M formic acid. Ignore any changes in volume.
