Answer:
Gas B
Explanation:
diffusion/effusion increases when:
- Temperature increases
- A gas has lower molar mass
- Particles are moving quickly
diffusion/effusion decreases when:
- Temperature decreases
- A gas has higher molar mass
- Particles are moving slowly
Hence: since gas B has the lowest molar mass, it has the highest rate of effusion
I also took the test so I know it is right
As Bond energy is between carbon and oxygen the is 358 for a single bond of C-0 and 745 for a double bond is the c=0.
- In the first step the one atom pulls the electron from another atom
. In the second step that is forming bonds releases energy and is the exothermic
. In the third step they pull electrons away from other elements
.
- In the last step the additional bonds is needed more energy to make or break, so the bond energy is very higher Hence the -153.

Answer:
The specific rotation of D is 11.60° mL/g dm
Explanation:
Given that:
The path length (l) = 1 dm
Observed rotation (∝) = + 0.27°
Molarity = 0.175 M
Molar mass = 133.0 g/mol
Concentration in (g/mL) = 0.175 mol/L × 133.0 g/mol
Concentration in (g/mL) = 23.275 g/L
Since 1 L = 1000 mL
Concentration in (g/mL) = 0.023275 g/mL
The specific rotation [∝] = ∝/(1×c)
= 0.27°/( 1 dm × 0.023275 g/mL
)
= 11.60° mL/g dm
Thus, the specific rotation of D is 11.60° mL/g dm
D. to preserve the union. He changed the meaning of the war when he passed the Emancipation Proclamation in 1863.
Hope this helps. Please let me know if I'm wrong :)
Answer:
Gravitational potential energy of water behind the dam
Explanation:
Energy can be defined as the ability (capacity) to do work. The two (2) main types of energy are;
a. Gravitational potential energy (GPE): it is an energy possessed by an object or body due to its position above the earth.
b. Kinetic energy (KE): it is an energy possessed by an object or body due to its motion.
Hydroelectric power plant refers to a renewable source of energy used for the generation of electricity, through the use of powerful hydraulic steam turbines operating at high voltage and are being driven by the energy acquired by water falling from a height and flowing through a penstock (pipe) i.e the mechanical energy (gravitational potential energy + kinetic energy).
At a hydroelectric power plant, potential energy is changed into kinetic energy. The kinetic energy is then transformed into electrical energy.
The source of the energy that turns the turbine in the power plant is Gravitational potential energy of water behind the dam, usually from streams or rivers.
