Suppose that 0.650mol of methane, \rm CH_4(g), is reacted with 0.800mol of fluorine, \rm F_2(g), forming \rm CF_4(g) and \rm HF(g) as sole products. Assuming that the reaction occurs at constant pressure, how much heat is released?
What would those concentrations be if you added HCl or NaOH to bring the pH to 3.2 or 7.35, respectively
How much heat is required to convert 25.0g of ethanol at 25 degrees C to the vapor phase at 78 degrees C?
Suppose that Mt=Lt=0.1M (exactly) and the pH is somehow fixed at 5.00. (This means that the charge balance no longer applies.) Use the equilibria and the two mass balances to find the concentrations of ML+, M+2, L-, HL.
suggest a procedure you could follow to determine whether it was necessary to use this solution as a reference or whether distilled water would have been just as satifactory
Using concentrations, the solubility of [Ag+] in a solution of 0.01 M KCl is 1.8 * 10-8. Calculate the percent relative error when using concentrations for the solubility of [Ag+] compared to activities
A 12V automotive lead-acid battery. Each anode/cathode pair in this schematic cutaway produces a voltage of about 2V. Six pairs of electrodes are connected in series, producing12V.
At what temperature will the bottom of a column of mercury of height 30.0 feet be expected to freeze? Use the data given below for mercury:
Can someone please explain to me how to identify the ion when you are given its last electron with the following quantum numbers?
Which of the following statements is true regarding chiral carbons with R configuration? a. plane polarized light is rotated clockwise b. plane polarized light is rotated counterclockwise
4 PH3(g) -> P4(g) + 6 H2(g) If, in a certain experiment, over a specific time period, 0.0039 mol PH3 is consumed in a 1.8 L container during each second of reaction.
how many grams of CaCl 2 would be required to produce a 3.5 M(molar) solution with a volume of 2.0 L?
Determine if the following reactions will form a precipitate when mixed. If one is formed, write the BALANCED formula unit, the COMPLETE IONIC, and NET IONIC equations. If a precipitate doesn't form, write NR for no reaction
