CO + 2H2 ⇌ CH3OH ΔH <0
sveta [45]

Answer:

C. The energy released as the bonds in the reactants are broken is greater than the energy absorbed as the bonds in the product are formed.

Explanation:

  • CO + 2H₂ ⇌ CH₃OH     ΔH <0

As ΔH is negative, the given reaction is exothermic.

That means that <em>the enthalpy of the product is less than the enthalpy of the reactants</em>. In other words, part of the energy from the reactants is used to form new bonds (between C and H, for example), while the other part is transfered outside the system as heat.

Thus the correct answer is C.

Why is coal and fossil fuels a nonrenewable resource
Tems11 [23]

Answer:

It is a finite resource. Fossil fuels such as oil, natural gas, and coal are examples of nonrenewable resources. Humans constantly draw on the reserves of these substances while the formation of new supplies takes eons. Renewable resources are the opposite: Their supply replenishes naturally or can be sustained.
