At STP, in the equation C(g) + O2(g) --> CO2(g), one liter of O2 yields how many liters of CO2?

3 I think but ask someone else too

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.

dynamic equilibrium is the answer.
