d. Twice as many moles of NO, form as moles of NO are consumed. True or False?
e. Twice as many grams of NO, form as grams of NO are consumed. True or False?
2. Given the following equation: N2(g) + 3H2(g) → 2NH(g) There are six different mole ratios in this system.
Write out each one.
3. Given the following equation: 4NH3(g) + 6NO(g) → 5N2(g) + 6H2O(g)
a. What is the mole ratio of NO to H. O?

Under which circumstances are kp and kc equal for the reaction aa(g)+bb(g)⇌cc(g)+dd(g)?

Gusing the milligrams of ascorbic acid you entered above, the ratio of total sample volume to aliquot volume, and the total milligrams of the vitamin c tablet that you dissolved, calculate the mass of ascorbic acid in the vitamin c tablet for each trial. do this by scaling up to find the amount (mg) of ascorbic acid in your 250 ml flask. enter your calculated mass of ascorbic acid in the vitamin c tablet, for each trial. be sure to enter your calculated mass in the corresponding order that you entered your milligrams of ascorbic acid. the milligrams of ascorbic acid you entered for entry #1 previously should correspond to the mass of ascorbic acid that you enter for entry #1 here.
