Methane burns in oxygen to produce carbon dioxide and water. which of the tollowing represents a preliminary, unbalanced equation with the correct chemical formulas?

So first we need to know what the formulas are:

Methane:

Oxygen:

Carbon Dioxide:

Water:

So then we follow the equation as specified in the question. Note that it does not need to be balanced, as the question states it wants the unbalanced equation:

→

This is the preliminary, unbalanced equation with the correct chemical formulas.

that's what i got you can count the number of atoms

consider the reaction below.

 no rx

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m

what is the equilibrium constant for the given reaction?

0.042

0.42
