The value of ΔG is -170 kJ/mol at 1000 K if ΔH is -220 kJ/mol and ΔS is -0.05 kJ/mol K.
Hence, option (D) is correct answer.
Gibbs free energy is also called free energy, free enthalpy, Gibbs energy which is used to measure the capacity of a system to do work in a thermodynamic system. It is denoted by the symbol 'G'.
To calculate the change in free energy as
ΔG = ΔH - T ΔS
where,
ΔG = Change in free energy
ΔH = Enthalpy change
T = Temperature in Kelvin
ΔS = Entropy change
Now put the value in above formula we get
ΔG = ΔH - T ΔS
= -220 kJ/mol - (1000 K) (-0.05 kJ/mol K)
= -220 + 50
= -170 kJ/mol
Thus, from above conclusion we can say that The value of ΔG is -170 kJ/mol at 1000 K if ΔH is -220 kJ/mol and ΔS is -0.05 kJ/mol K.
Hence, option (D) is correct answer.

solution of KOH, what is the concentration of
HNO3?
(1) 1.0 M (3) 3.0 M
(2) 1.5 M (4) 0.5 M
Answer : The correct option is, (2) 1.5 M
solution :
According to the neutralization law,
where,
= molarity of solution = ?
= volume of solution = 50 ml
= molarity of KOH solution = 0.50 M
= volume of KOH solution = 150 ml
Now put all the given values in the above law, we get the volume of solution.
Therefore, the concentration of is, 1.5 M
Answer:
filtration: pore sizes less than 0.45 micrometers
Explanation:
b. move from their ground states up to excited states.
c. attach to the nucleus.
d. form a bond with the nearest proton.
When electrons absorb energy they are able to move from their ground states up to excited states. The answer is letter B. an example of this is when you light a match. The molecules of the matchstick are in its ground state. When you flick it on the ground or anything hard, it causes its molecules to move into the excited state and thus causing fire.
c. Diluted, and
d. soluble
the answer will be b)
2) 0.000023
3) 101,000
4) 0.010
5) 45.01
6) 1,000,000
7) 0.00671
8) 4.50
The question asked about converting normal numbers into scientific notation. The answer provided the eight scientific notation equivalents for each of the numbers provided in the question, explaining the process of calculating them.
To write numbers in scientific notation, we have to express them in the form of a x 10^n, where 1 <= a < 10 and n represents the number of places the decimal place has been moved. Let's proceed with each given number:
