The diagram below shows the energy conversions of the Krebs cycle, which is part of cellular respiration. The U-shaped

VLD [36.1K]

Answer:

i dont even know tbh jk i wont waste ur time unless nvm ok so the answer is The correct answer would be C.10. Krebs cycle is a part of cellular respiration that takes place in the mitochondria. Five energy conversions take place in one complete cycle of the Krebs cycle. These conversions lead to the formation of three molecules of NADH, one molecule of FADH₂ and one molecule of ATP.

How can a rock form by evaporation?What type of rock is it

Vedmedyk [2.9K]

Crystsals can precipitate out of solution when some of the solvent is evaporated. For example, if you have sodium chloride in solution and you evaporate out the water some sodium chloride crystals will form. I hope this helps. Let me know if anything is unclear.

Consider 5.00 L of a gas at 365 mmHg and 20. ∘C . If the container is compressed to 2.30 L and the temperature is increased to 4

lakkis [162]

Answer:

P₂ = 1.12 atm

Explanation:

To find the new pressure, you need to use the Combined Gas Law:

$\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}$

In this equation, "P₁", "V₁", and "T₁" represent the initial pressure, volume, and temperature. "P₂", "V₂", and "T₂" represent the new pressure, volume, and temperature. Before plugging the values into the equation, you need to

(1) convert the pressure from mmHg to atm (760 mmHg = 1 atm)

(2) convert the temperatures from Celsius to Kelvin (°C + 273)

The final answer should have 3 sig figs like the given values.

P₁ = 365 mmHg / 760 = 0.480 atm P₂ = ? atm

V₁ = 5.00 L V₂ = 2.30 L

T₁ = 20°C + 273 = 293 K T₂ = 40°C + 273 = 313 K

$\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}$ <----- Combined Gas Law

$\frac{(0.480 atm)(5.00 L)}{293 K}=\frac{P_2(2.30 L)}{313 K}$ <----- Insert values

$0.00819=\frac{P_2(2.30 L)}{313 K}$ <----- Simplify left side

$2.56 = P_2(2.30L)$ <----- Multiply both sides by 313

$1.12 = P_2$ <----- Divide both sides by 2.30

Light travels through space at 186,282 miles per second and it takes about 1.3 seconds for light to travel from the moon to Eart

PIT_PIT [208]

The correct method would be multiplying the speed of light by the time it takes to travel from the moon to Earth. This is because:

S=So+V*t

In which:

S= space

So= space at the start (origin)

V=speed or velocity

t=time

By multiplying miles/second by seconds you get miles as a result.

Is the temperature at which a substance melts the same as the temperature changes from a liquid to a solid

sasho [114]

Answer:

No.

Explanation:

If the temperature changes a substance from it's original form, going from solid to liquid, then the temperature required to change it from a liquid to a solid are the opposite. For example, Ice is Water (H2O) in it's solid form. In order to freeze water into ice, the temperature must be very low. In order to melt the ice back into water, the temperature must be higher than the freezing point, but not too high or it will boil, making it a gaseous substance instead.
