Consider a galvanic cell with a beaker of sulfuric acid and a beaker of nitric acid. The sulfuric acid beaker contains a strip of tin, and the nitric acid cell contains a strip of platinum. A wire runs between the strips. The reaction that occurs is as follows: 3Sn(s) + 2 * N*O_{3} ^ (- (aq)) + 8H ^ (aq) 3Sn^ 2+ (aq)+2NO(g)+4H 2 O(l) In three to five sentences, list which electrode is the anode and which is the cathode and the half reactions that occur at each electrode.
In this galvanic cell, the tin strip in the sulfuric acid beaker is the anode, while the platinum strip in the nitric acid beaker is the cathode. At the anode, the half-reaction that occurs is Sn(s) -> Sn2+(aq) + 2e-. At the cathode, the half-reaction that occurs is 2NO3-(aq) + 8H+(aq) + 6e- -> 2NO(g) + 4H2O(l).

is this balanced?
\[2 \mathrm{Fe} + 3 \mathrm{H}_{2} \mathrm{SO}_{4} \rightarrow1 \mathrm{Fe}_{2}\left(\mathrm{SO}_{4}\right)_{3} + 4 \mathrm{H}_{2}\]
No, the equation you provided is not balanced. The balanced equation for the reaction you presented is:
\[2 \mathrm{Fe} + 3 \mathrm{H}_{2} \mathrm{SO}_{4} \rightarrow1 \mathrm{Fe}_{2}\left(\mathrm{SO}_{4}\right)_{3} + 3 \mathrm{H}_{2}\mathrm{O}\]
Balanced chemical reactions obey the law of conservation of mass?
true or false?
True.
Balanced chemical reactions obey the law of conservation of mass, which states that matter is neither created nor destroyed in a chemical reaction. The total number of atoms of each element in the reactants must be equal to the total number of atoms of each element in the products.
If i have 8 moles of iron atoms in the products, how many moles of iron atoms did i start with?

not enough information
To determine the number of moles of iron atoms that were initially present, we need additional information. The balanced chemical equation does not directly provide information about the stoichiometry between the reactants and products. We would need to know the coefficients of the iron atoms in the reactants to calculate the number of moles of iron atoms initially present. Therefore, the correct answer is "not enough information."
Consider a galvanic cell with a beaker of Chromium(III) nitrate Cr (N*O_{3}) 3 and a beaker of Copper(II) nitrate Cu (N*O_{3}) 2 . The Chromium(ll) nitrate beaker contains a strip of chromium, and the Copper(II) nitrate cell contains a strip of copper. A wire runs between the strips. The reaction that occurs is as follows:
2Cr(s)+3Cu^ 2+ (aq) 2Cr^ 3+ (aq) + 3Cu(s)
In three sentences, list which electrode is the anode and which is the cathode and the half reactions that occur at each electrode. (4 points)
