What did Lorenzo Romano Amedeo Carlo Avogadro theorize in 1811?

Chemistry

Answer:

He theorized that equal volumes of gases at the same temperature and pressure contain equal numbers of molecules.

Explanation:

In 1811, Avogadro published an article in a scientific journal, where he distinguished between molecules and atoms. He argued (contrary to what was thought) that in the case of water, the hydrogen and oxygen "atoms" were actually "molecules." One molecule of oxygen would react with two molecules of hydrogen (H2O).

Thus he proclaimed his famous hypothesis: "Equal volumes of any gases contain the same number of molecules when measured under the same conditions of temperature and pressure."

Avogadro's law, which states that equal volumes of gases under the same conditions of temperature and pressure will contain equal numbers of molecules.

Light shining on a strip of metal can dislodge electrons. Do you think this is more consistent with light being made up of waves
Naya [18.7K]

Answer:

The correct answer to the following question will be "Particles".

Explanation:

  • A particle seems to be a little component of something, it's little. When you're talking about a subatomic particle, that would be a structured user likely won't see because it's quite unbelievably thin, but it has a tiny mass as well as structural integrity. Such particles seem to be tinier than that of the particles or atoms.
  • Such that the light which shines on the bit of metal could dissipate electrons, the particles seem to be more compatible with the light.

What is the heat of combustion of ethane, c2h6, in kilojoules per mole of ethane? Enthalpy of formation values can be found in t
Andre45 [30]

The balanced combustion reaction for one mole of ethane will be

C2H6 + 3.5 O2  ---> 2CO2(g) + 3H2O (l)

Enthalpy of reaction of combustion = ∑ΔHf (products)- ∑ΔHf (reactant)

ΔHf = enthalpy of formation

The enthalpy of formation of oxygen = 0 as it is an element in its native state

ΔHf C2H6 = -83.820 kJ / mole

ΔHf H2O = -285.830 kJ / mole

ΔHf CO2 = -393.509 kJ / mole

ΔHrxn = [2 X ΔHf CO2 + 3 X ΔHf H2O] - [ΔHf C2H6]

ΔHrxn = [2 X (-393.509) + 3 (-285.830)] - [-83.820]

ΔHrxn = -1560.688 kJ / mole
