Hello , please help me to answer the following 3
questions:
Fe_2O_3(s) + CO_(g) rightarrow Fe_(S) + CO_2(g) (unbalanced) Calculate the number of grams of CO that can react with 0.517 kg of Fe_2O_3. Consider the following equation: N_2(g) + 3 H_2(g) rightarrow 2 NH_3(g), how many molecules of ammonia are produced when 36.5 liters of hydrogen react at STP (in excess nitrogen)? Given C_3H_8 + O_2 rightarrow CO_2 + H_2O (balance the equation) When 25.0 grams of C_3H_8 react...

I'm working on a chemistry question and can't seem to find the answer. Someone please help!! B. What is the charge on each of the following complex ions? hexaaquamanganese(II), [Mn(H2O)6]?[Mn(H2O)6]? tris(carbonato)ferrate(III), [Fe(CO3)3]?[Fe(CO3)3]? diaquatetrachlorovanadate(III), [V(H2O)2Cl4]?[V(H2O)2Cl4]? Express the charges numerically, in the order that the complexes are listed, separated by commas. For a nonzero charge, be sure to include the sign (e.g., +1,-2,+3). C. What is the oxidation number of the central metal ion in each of the following complexes or compounds?...
Please note: This is 1 practice organic chemistry question with
6 parts to answer!!!! If you are unable to answer any of the parts
PLEASE leave question alone for the next expert!
Here are the 6 parts that require help:
1. Give full curved arrow pushing for the mechanism above.
2. Indicate if product is optically active or not..
3. Give a pictorial representation of the frontier molecular
orbital ON TOP of the provided structure for A and B.
4....
please answer the full question.
2. You measured cell potentials (voltages) for reactions of metals and metal ions. We will use the standard date and practice calculating these. Recall: E-Ecathode - Eanode Remember reduction occurs at the cathode; oxidation occurs at the anode For the anode reactions, your reactant will be on the product side of the standard equation, but don't change any sign. The equation does that for you. Cathode Reaction Agt + e → Ag Ecathode Anode Reaction...
