In the reaction

2 CO + O2 → 2 CO2,

what is the minimum number of moles of O2 required to produce 1.0 mole of CO2?
A
0.25

B
0.50

C
1.0

D
2.0

The minimum number of moles O2 needed is 0.50 moles (option B)

Explanation:

Step 1: Data given

Number of moles CO2 produced = 1.0 moles

Step 2: The balanced equation

2 CO + O2 → 2CO2

Step 3: Calculate moles of O2

For 2 moles CO we need 1 mol O2 to produce 2 moles CO2

For 1.0 mol CO2 produced, we need 1.0 / 2 = 0.50 moles O2

The minimum number of moles O2 needed is 0.50 moles (option B)

d: the voltage of the secondary coil is less than that of the primary coil.

im not suree sorry if wrong

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
