Explanation:
We know that molarity is the number of moles of solute present in liter of solution.
Mathematically, Molarity = 
As molarity is dependent on volume and volume of a solution or substance is dependent on temperature. So, with increase in temperature there will occur a decrease in volume of the solution. As a result, molarity will increase as it is inversely proportional to volume.
Hence, molarity of both the solutions will be different as temperature of both the solutions is different.
4.5 L
Explanation:
We will use the combined gas law formula;
P₁V₁/T₁ = P₂V₂/T₂
Because the pressure remains the same, it cancels out and what remains is;
V₁/T₁ = V₂/T₂
Before evaluating remember to change the temperatures into Kelvin;
-23° = 250.15 K
177° = 450.15 K
We replace the variables with known values;
2.5 / 250.15 = V₂ / 450.15
V₂ = 2.5 /250.15 * 450.15
V₂ = 4.4988 L
≅ 4.5 L
Answer:
6CO2 + 6H2O ----> C6H12O6 + 6O2
Explanation:
Photosynthesis is the process by which green plants manufacture their own food using sunlight in the presence of carbon dioxide water and chlorophyll.
Chlorophyll is the pigment in plants that absorbs light.
The equation of photosynthesis is shown in the answer section above. Sugar and oxygen are the first products of photosynthesis.
Answer:
The system makes the transition from nonspontaneous to spontaneous at a temperature of 954.7 K.
Under 954.7 K the reaction is nonspontaneous; more than 954.7 K is the reaction spontaneous.
Explanation:
CH4(g) + 2H2O(g) ⇆ CO2(g) + 4H2(g)
CH4(g) H2O(g) CO2(g) H2(g) ΔH°f (kJ/mol): –74.87 –241.8 –393.5 0
ΔG°f (kJ/mol): –50.81 –228.6 –394.4 0
S°(J/K·mol): 186.1 188.8 213.7 130.7
ΔG<0 to be spontaneous
ΔG = ΔH- TΔS <0
ΔH = ∑nΔH(products) - ∑nΔH(reactant)
ΔH = (-393.5) - (–74.87 + 2*–241.8)
ΔH = 164.97 kJ = 164970 J
ΔS = ∑nΔS(products) - ∑nΔS(reactant)
ΔS = (213.7 + 4*130.7) - (186.1 + 2*188.8)
ΔS = 172.8 J
0 > 164970 J - T* 172.8 J
-164970 J > - T* 172.8 J
954.7< T
The system makes the transition from nonspontaneous to spontaneous at a temperature of 954.7 K.
Under 954.7 K the reaction is nonspontaneous; more than 954.7 K is the reaction spontaneous.
Answer:
both
Explanation:
A homolytic fission is said to have occurred when the breakage of a bond between two atoms leaves each of the bonding atoms with equal number of electrons. Homolytic fission often results in the creation of radicals.
Since homolytic fission yields two species with equal number of electrons(usually odd number of electrons), the products of such process can not be charged. They can not be nucleophiles because nucleophiles need to possess two electrons which can be shared with another chemical specie.
