Because the intention is to boil the solution, the purpose of the solvent is to dissolve so it has a higher boiling point so ensure it stays in liquid form and doesn't evaporate into a gas
also, a pure solvent is made of 1 substance so it has 1 boiling point and the solution must evaporate/boil first
Glucose is C6H12O6.
so u simply need to add the individual masses of 6 carbons, 12 hydrogens and 6 oxygens.
the molecular mass of carbon is 12 but if u take it as 40..
them it would be..
6x40+12x1+6x16= whatever u get in your calc. ;)
Answer:
The original volume of the gas is 0.001 mL
Explanation:
This easy excersise can be solved by the law for gases, about pressure and volume; the volume of a gas is inversely proportional to the pressure it exerts.
We can propose the rule by this formula:
P₁ / V₁ = P₂ / V₂
We replace data given: 1.50 atm / V₁ = 0.50 atm / 750 mL
As the rule says, that volume is inversely proportional, and the pressure was decreased, volume must be lower than 750 mL.
1.5atm / (0.5 atm / 750mL) = V₁
V₁ = 0.001 mL
Answer:
All of the choices are real advantages of alcohol fermentation - E)
For the reaction c2h6 (g) → c2h4 (g) + h2 (g) δh° is 137 kj/mol and δs° is 120 j/k ∙ mol. the reaction is spontaneous at high temperatures. the correct answer is option(b).
A spontaneous reaction is one that favors the creation of products in the environment in which it is taking place. A campfire that is roaring is an exothermic example of a spontaneous reaction (there is a decrease in the energy of the system as energy is released to the surroundings as heat).
There are some reactions that are only spontaneous at very high temperatures according to the Gibbs Free Energy equation. The reaction is spontaneous at high temperatures if both S, or entropy, and H, or enthalpy, are positive. We want the Gibbs free energy to be negative according to the formula G = H - T - S.
The complete question is:
For the reaction
C2H6 (g) → C2H4 (g) + H2 (g)
ΔH° is +137 kJ/mol and ΔS° is +120 J/K ∙ mol. This reaction is ________.
A) spontaneous at all temperatures
B) spontaneous only at high temperature
C) spontaneous only at low temperature
D) nonspontaneous at all temperatures
