Answer:
The Gibbs free energy is -2997.83 kJ mol-1.
Explanation:
The change in Gibbs free energy of the reaction can be calculated using the formula.
WHere R = Gas constant = 8.314KJ/Kmol
T = the temperature of the reaction in Kelvin = (37.0 + 273) = 310K
K = Raio of molar concentration of the two reactants = 1.6/0.5 = 3.2
Therefore,
Therefore the Gibbs free energy is -2997.83 kJ mol-1.
The negative sign indicates that the reaction is spontaneous.
Answer:
The empirical formula of this question is :
C.
Explanation:
The empirical formula is the simplest whole number ratio of elements in the chemical formula of the molecule.
It is calculated using:
n = The common factor
The Molecular formula represents the exact composition of the elements in the compound.
For example :
Molecular formula : C4H8O2
<em>Find the common factor n ?</em>
<em>here , 2 is common factor(which is divisible by 4 ,8,2)</em>
divide each element by 2
generally 1 is not written
C2H4O is the empirical formula
In this question , the molecular formula C40H56
n = common factor = 8(It is divisible by 40 , 56 )
So, correct option is<u> C</u>
Answer:
V₂ = 5.97 L
Explanation:
Given data:
Initial temperature = 9°C (9+273 = 282 K)
Initial volume of gas = 6.17 L
Final volume of gas = ?
Final temperature = standard = 273 K
Solution:
Formula:
The Charles Law will be apply to solve the given problem.
According to this law, 'the volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure'
Mathematical expression:
V₁/T₁ = V₂/T₂
V₁ = Initial volume
T₁ = Initial temperature
V₂ = Final volume
T₂ = Final temperature
Now we will put the values in formula.
V₁/T₁ = V₂/T₂
V₂ = V₁T₂/T₁
V₂ = 6.17 L × 273K / 282 k
V₂ = 1684.41 L.K / 282 K
V₂ = 5.97 L
Answer:
D. Territory
Explanation:
Territory is defined as an area that is claimed by one or more individuals.
Territory is often used as a form of ownership of land or water mass between two parties. It is important as it gives each party a knowledge of their designated areas.
This validates it being an area that is claimed by one or more parties as organisms use that to protect their interest of food, water and mates for their survival.
