Because they're just meant to be arranged by atomic mass--it's just how the scientists of the late 1860s wanted it to be ordered

Veseljchak [2.6K]

Answer:

Speed of light

Explanation:

The value 3.0 x 10⁸m/s is taken as the speed of light.

It is a constant.

  • It implies that light travels a distance of 3 x 10⁸ in just one second.
  • This value is for the speed of light in a vacuum when there are not particles obstructing its movement.
  • The speed of electromagnetic radiations in free space is also taken as the speed of light.

Which of the following statements is true of combustion reactions?
enot [183]

Gasoline contains C and H atoms. During combustion, the carbon (C) from the fuel combines with oxygen (O2) from the air to produce carbon dioxide (CO2).
2 C8H18 + 25 O2 → 16 CO2 + 18 H2O.

Combustion reactions release large amounts of heat. They have negative enthalpy. A negative enthalpy represents an exothermic reaction, releasing heat. This reaction is spontaneous and exothermic, since we can obtain energy from the reaction; the ΔG (free energy) is negative (So 1 is true).

ΔG < 0, so the free energy of the system decreases with the reaction. Remember that when there is a negative ΔG the reaction goes from higher free energy to lower free energy, like in this case.
