The titration of water soluble vitamin C found 14.50 mL of 0.200 M NaOH was required to react completely with 0.670 g of vitamin C tablet. What is the percentage of Ascorbic acid in this Vitamin C tablet? Vitamin C active ingredient is Ascorbic acid and it reacts with NaOH as below. Molecular formula of Ascorbic Acid is HC6H7061 Enter only numerical answer without % mark] HC6H70. (aq) + NaOH(aq) = H20 (1) + NaC.H70. (aq)Personal Finance2 weeks ago
Predict the sign of delta S of the system:
1. 2C (graphite) +O2 (g)--> 2CO (g)
2. C4H10(g)--> C4H10(l)
A. Delta S should be negative for both
B. Delta S should be negative for 1 and positive for 2
C. Delta S should be positive for 1 and negative for 2
D. Delta S should be positive for both
I got -2 but I am not sure if that is right, or how to integrate the graph into solving1 AnswerMathematics2 weeks ago
The reaction is FeCl3+ 3K2C2O4+ 3H2O -> K3Fe(C2O4)3 * 3H2O + 3KCl
The moles of FeCl3 were found to be 0.0123 mol, so you have to use this to find the moles of K3Fe(C2O4)3 * 3H2O and then convert to grams to get theoretical yield.
The stoichiometry is what is confusing me to find the moles of K3Fe(C2O4)3 * 3H2.
Solve for ∫ (-2 on top/over the sign, 4 under/bottom of sign) times f(x) dx. From my research you have to find F(x) first but Im not sure how or where to start to apply and use the law of definite integrals to solve3 AnswersMathematics3 weeks ago
