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.
The measure of the quantity of heat exchanged.
Uses many different units of measurements.
Answer: spring tides
When earth, moon, and sun line up cause high and low tides :)
Answer:
n=N/Na
n = \frac{8.23 \times {10}^{22} }{6.02 \times {10}^{23} } = 0.1367 \: mol
answer: 0.14 mol
Explanation:
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
