The answer is D. FOOD

EXPLANATION:

Umm it’s not mitosis because that’s stages of cell division to help the skin grow back etc.

Heat can be an energy but for this context it’s not the right answer.

Water isn’t technically correct...

will give brainliest!! please help ! .. Calculate the total pressure of the mixture in atmospheres ( atm ).
nordsb [41]

Answer:

13.94 atm

Explanation:

From the question given above, the following data were obtained:

Pressure of H₂ = 2 atm

Pressure of NH₃ = 303 KPa

Pressure of CO₂ = 3000 mmHg

Pressure of N₂ = 3800 torr

Total pressure (Pₜ) in atm =?

Next, we shall convert 303 KPa, 3000 mmHg and 3800 torr to atm.

This can be obtained as follow:

Converting 303 KPa to atm

101.325 KPa = 1 atm

Therefore,

303 KPa = 303 KPa × 1 atm / 101.325 KPa

303 KPa = 2.99 atm

Thus, 303 KPa is equivalent to 2.99 atm.

Converting 3000 mmHg to atm

760 mmHg = 1 atm

Therefore,

3000 mmHg = 3000 mmHg × 1 atm / 760 mmHg

3000 mmHg = 3.95 atm

Thus, 3000 mmHg is equivalent to 3.95 atm

Converting 3800 torr to atm

760 torr = 1 atm

Therefore,

3800 torr = 3800 torr × 1 atm / 760 torr

3800 torr = 5 atm

Thus, 3800 torr is equivalent to 5 atm.

Finally, we shall determine the total pressure of the mixture as follow:

Pressure of H₂ (P₁) = 2 atm

Pressure of NH₃ (P₂) = 2.99 atm

Pressure of CO₂ (P₃) = 3.95 atm

Pressure of N₂ (P₄) = 5 atm

Total pressure (Pₜ) in atm =?

Pₜ = P₁ + P₂ + P₃ + P₄

Pₜ = 2 + 2.99 + 3.95 + 5

Pₜ = 13.94 atm

Therefore, the total pressure of the mixture is 13.94 atm

a 0.555 g sample of mayonnase was burned in excess oxygen inside a bomb calorimeter with a total heat capacity (bomb and water)
Fofino [41]

Answer:

Dietary\ Calories=65.6kcal

Explanation:

Hello!

In this case, since we can see that the heat released by the combustion of the mayonnaise is absorbed by the bomb calorimeter and water, we can set up the following equation:

m_{mayonnaise}q_{mayonnaise}=C\Delta T

Whereas q for mayonnaise stands for the heat due to its usage; thus, we plug in to obtain:

q_{mayonnaise}=\frac{5.20kJ/\°C*2.93\°C}{0.555g} \\\\q_{mayonnaise}=27.45\frac{kJ}{g}

Now, if 10.0 g are eaten, the energy provided by it turns out:

E_{mayonnaise}=27.45kJ/g*10.0g\\\\E_{mayonnaise}=274.5kJ

And we need that value in dietary calories, 1 kcal:

Dietary\ Calories=274.52kJ*\frac{1kcal}{4.184kJ}\\\\ Dietary\ Calories=65.6kcal

Best regards!
