What is the value for AG at 100 K if AH = 27 kJ/mol and AS = 0.09 kJ/mol.K)?
O A. AG = 2700 kJ/mol
B. AG = -36 kJ/mol
C. AG = 0 kJ/mol
D. AG = 18 kJ/mol
The value for ΔG = 18 kJ/mol
Further explanationGiven
ΔH = 27 kJ/mol and ΔS = 0.09 kJ/mol.K
T = 100 K
Required
the value for ΔG
Solution
The spontaneous process of a reaction is based on 2 factors :
enthalpy change ΔH decreases and entropy change ΔS increasesΔG=ΔH-T.ΔS
[tex]\tt \Delta G=27~kJ/mol-100\times 0.09~kJ/mol.K\\\\\Delta G=18~kJ/mol[/tex]

Electrical devices have been designed to convert electrical energy to other useful
forms of energy. Choose the device which converts electrical energy to kinetic
energy.
Answer:
B. Fan
Explanation:
The device in the options which converts electrical energy to kinetic
energy is the Fan.
When the fan is plugged to a an electric power source, the electrical energy gets converted to kinetic energy as a result of the movement of the blades in which Kinetic energy is defined as the energy as a result of the motion of a particle or substance.

Tony sets up an experiment inside his classroom. He spaces 5 plants at equal distances along a straight line, with the first plant directly in front of a window and the last plant 10 meters (m) away from the window. He gives them equal access to air and water and then monitors the amount of gas each plant releases.
Which gas is Tony monitoring and what trend is he most likely to see in the data he collects?
He is monitoring oxygen. The amount of gas released should be highest for the plant in the middle and lowest for the plants at the ends.
He is monitoring carbon dioxide. The amount of gas released should be highest for the plant in the middle and lowest for the plants at the ends.
He is monitoring oxygen. The amount of gas released should be highest for the plant closest to the window and lowest for the plant farthest away from the window.
He is monitoring carbon dioxide. The amount of gas released should be highest for the plant closest to the window and lowest for the plant farthest away from the window.
Answer:
I believe the answer is
"He is monitoring oxygen. The amount of gas released should be highest for the plant closest to the window and lowest for the plant farthest away from the window."

What is the mass of LaTeX: 2.486 * 10^{24} atoms of neon?
Select one:
a. 83.33 g Ne
b. 0.2046 g Ne
c. 8.333 g Ne
d. 4.130 g Ne
Answer:
Mass = 83.33 g
Explanation:
Given data:
Number of atoms of neon = 2.486×10²⁴
Mass of neon = ?
Solution:
Avogadro number:
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance. The number 6.022 × 10²³ is called Avogadro number.
1 mole = 6.022 × 10²³ atoms
2.486×10²⁴ × 1 mol / 6.022 × 10²³ atoms
0.413×10¹ mol
4.13 mol
Mass of neon:
Mass = number of moles × molar mass
Mass = 4.13 mol × 20.18 g/mol
Mass = 83.33 g
how many electrons does the neutral atom pictured have?
A) 5
B) 6
C) 7
D) 8
Answer:
5
Explanation:
Protons are depicted in this picture as +, and the no. of protons are always equal to the no. of electrons (unless it's an ion).
Over here, there are 5 protons therefore there should also be 5 electrons.
A pharmacist mixed some 10%-saline solution with some 15%-saline solution obtain 100 mL of a 12%-saline solution. How much of the 10-saline solution did the pharmacist use in the mixture
Answer:
10%-saline solution = 60mL
15%-saline solution = 40mL
Explanation:
Let
10%-saline solution = x
15%-saline solution = y
x + y = 100
0.1x + 0.15y = 100*0.12
x + y = 100 (1)
0.1x + 0.15y = 12 (2)
from (1)
x = 100 - y
Substitute x = 100 - y into
0.1x + 0.15y = 12
0.1(100 - y) + 0.15y = 12
10 - 0.1y + 0.15y = 12
- 0.1y + 0.15y = 12 - 10
0.05y = 2
y = 2 / 0.05
y = 40mL
Substitute y = 40 into
x + y = 100
x + 40 = 100
x = 100 - 40
x = 60mL
10%-saline solution = 60mL
15%-saline solution = 40mL
It requires energy to melt ice. Applying salt to the ice created a chemical reaction melting the ice. Were did the energy come from to melt the ice? *
Answer:
HOPE IT HELPS...
Explanation:
When added to ice, salt first dissolves in the film of liquid water that is always present on the surface, thereby lowering its freezing point below the ices temperature. Ice in contact with salty water therefore melts, creating more liquid water, which dissolves more salt, thereby causing more ice to melt, and so on

Blaire is teaching her little brother to ride his bike. She uses 7 N of force to push a 14 kg bike. What is the acceleration?
98 m/s2
0.5 m/s2
21 m/s2
2 m/s2
Answer:
The solution is
Explanation:
a = f/m
a =7/14
a=1/2
a=0.5
Acceleration of bike is 0.5 m/s²
Given that:Force used in push = 7 N
Mass of bike = 14 kg
Find:Acceleration of bike
Computation:Force = Mass × Acceleration
Force used in push = Mass of bike × Acceleration of bike
7 = 14 × Acceleration of bike
Acceleration of bike = 7 / 14
Acceleration of bike = 0.5 m/s²
