The following two reactions are important in the blast furnace production of iron metal from iron ore (Fe2O3):2C(s) + O2(g) -&gt

Inga [223]

Answer: A) 67.1 moles

Explanation:

The balanced reaction is :

$2C(s)+O_2(g)\rightarrow 2CO(g)$

$Fe_2O_3+3CO(g)\rightarrow 2Fe+3CO_2$

To calculate the moles, we use the equation:

$\text{Number of moles of iron}=\frac{\text{Given mass}}{\text {Molar mass}}=\frac{5.00\times 1000g}{56g/mol}=89.3moles$

According to stoichiometry;

2 moles of iron is produced by 3 moles of carbon monoxide

89.3 moles of iron is produced by= $\frac{3}{2}\times 89.3=134$ moles of carbon monoxide

2 moles of carbon monoxide is produced by = 1 mole of oxygen

Thus 134 moles of carbon monoxide is produced by = $\frac{1}{2}\times 134=67.1$ moles of oxygen

In a voltaic (galvanic) cell, oxidation occurs at the _____ and is where _____ in the salt bridge moves toward.

Anna11 [10]

In a voltaic (galvanic) cell, oxidation occurs at the anode and is where anions in the salt bridge moves toward.

<h3>What is Galvanic Cell ?</h3>

Galvanic Cell or Voltaic Cell is an electrochemical cell that converts the energy of spontaneous redox reactions into electrical energy. In galvanic cell oxidation occurs at the anode and reduction occurs at the cathode. The anode is positive and cathode is negative, anode attracts anions from solution in an electrolytic cell.

Thus from the above conclusion we can say that In a voltaic (galvanic) cell, oxidation occurs at the anode and is where anions in the salt bridge moves toward.

Ch4+br2=ch3br+hbr which type of reaction does this equation represent

Neporo4naja [7]

this could be a substitution reaction. as you will locate, between the hydrogen's on the propane chain replaced into substituted for a Br from Br2. that's particularly no longer a addition reaction! addition reactions artwork once you have a AlkENE! by using fact that's an AlkANE it would not have a double bond to act as a nucleophile to attack the Br2 (which might act as a electrophile to boot reactions).
