If 8.50 L of natural gas, which is essentially methane (CH4), undergoes complete combustion at 730 mm Hg and 20 degrees C, how many grams of each product are formed? Grams of CO2=
Grams of H2O=

mass CO₂ : 14.96 g

mass H₂O : 12.24 g

Further explanation

Reaction

CH₄+2O₂⇒CO₂+2H₂O

mol CH₄

V=8.5 L

P=730 mmHg=0,961 atm

T=20+273=293 K

mass CO₂(MW=44 g/mol)

mol CO₂= mol CH₄ = 0.34

mass H₂O (MW=18 g/mol)

mol H₂O= 2 x mol CH₄ = 2 x 0.34 = 0.68

The  grandmother cell  is a hypothetical  neuronthat represents a complex but specific concept or object.[1]  it activates when a person "sees, hears, or otherwise sensibly discriminates"[2]  a specific entity, such as his or her grandmother. the term was in use at least as early as 1966 amongst staff and students in the department of experimental psychology, university of cambridge, england. a similar concept, that of the  gnostic neuron, was proposed two years later
