2. Analyze the relationship between percent hydrogen peroxide and volume of gas produced by following the steps below. The graph shows the data collected for various samples with different Rercents, of hydrogen peroxide at 1.00 atm and 298 K. a. What is the percent hydrogen peroxide listed on the bottle? This is the theoretical percent| Theoretical percent: 3% b. On the graph below, locate the value of the volume in ml of O2 that you collected in your experiment. Trace this value from the y-axis to the plotted line and then from the plotted line down to the x-axis to find the percent hydrogen peroxide that corresponds to this volume of O2. Record value with one estimated decimal place. This is the experimental percent. Experimental percent: vo (mL) vs % H,O2 100.0 90.0 80.0 70.0 60.0 50.0 40.0 30.0 20.0 10.0 0.0 1 2 5 % hydrogen peroxide c. Calculate the percent error in your experiment by comparing the theoretical and experimental percents, using the equation below. experimental-theoretical % error = theoretical (ju)O A

Pls do fast and i will give like for sure Try to give solution in typed form

Consider the reaction: 4 PH3 (g) →  P4 (g)  +  6 H2 (g) In the reaction above, 0.075 mole of H2 is produced in a 2.0-L container over some time period. What concentration of PH3 is consumed over the same time period?
