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.

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
