You are going to heat up some soup. The first thing you need to do is turn off the natural-gas (methane) stove. When you ignite a natural-gas stove, methane (CH4) reacts with oxygen (O2) to produce carbon dioxide (CO2) and water vapor (H2O). Required:
a. Write a balanced equation for this reaction. Be sure to show your work.
b. What type of reaction is this? Describe the common reactants and products for this type of reaction.

Darla claims that the first periodic table developed by mendeleev was not completely accurate, so it is not useful at all. harmony argues that it establish the periodic table we use today, making it more credible. who is correct and why? darla is correct, because a model that has any mistakes should be thrown out. darla is correct, because a good model would not need to change. harmony is correct, because mendeleev’s model had all of the information correct in the first version. harmony is correct, because mendeleev’s model made predictions that came true.
