The wave will have a frequency that is larger
Answer:
C. C, because it’s the highest of all four and C is 2,5 which is medium but the highest one.
Answer:
359 grams FeO
Explanation:
To find how many grams FeO are produced, you need to use the moles of Fe, convert it to moles of FeO (using the mole-to-mole ratio from the equation), then convert the moles of FeO to grams (using the molar mass from the periodic table).
2 Fe + O₂ --> 2 FeO
Molar Mass (FeO) = 55.845 g/mol + 16.00 g/mol
Molar Mass (FeO) = 71.845 g/mol
5.00 moles Fe 2 moles FeO 71.845 grams

2 moles Fe 1 mole FeO
A fracture Formation .
A matter is neither destroyed or created
8H⁺ + 5Fe²⁺ + MnO₄⁻ ⇒ Mn²⁺ + 5Fe³⁺ + 4H₂O
<span>
According to the reaction, Fe</span>²⁺ and MnO4⁻<span> have following stoichiometric ratio:
n(</span>Fe²⁺) : n(MnO4⁻) = 5 : 1
n(MnO4⁻) = n(Fe²⁺) / 5
<span>
So, for each mole of </span>Fe²⁺ it is needed 1/5 moles of MnO4⁻.<span>
