<h3>Given:</h3>

P_{1} = \text{55.8 kPa}

T_{1} = -25^{\circ}\text{C + 273 = 248 K}

P_{2} = \text{145 kPa}

<h3>Unknown:</h3>

T_{2}

<h3>Solution:</h3>

\dfrac{P_{1}}{T_{1}} = \dfrac{P_{2}}{T_{2}}

T_{2} = T_{1} \times \dfrac{P_{2}}{P_{1}}

T_{2} = \text{248 K} \times \dfrac{\text{145 kPa}}{\text{55.8 kPa}}

\boxed{T_{2} = \text{644 K}}

The combustion of carbohydrates and the combustion of fats are both exothermic processes, yet the combustion of carbohydrates is
Julli [10]

Explanation:

There are two aspects of a reaction:

Thermodynamics:

Combustion of the compound is reaction with oxygen.

The carbohydrates contain more content of oxygen as compared to fats.

Hence, carbohydrates have lot of oxygen content which are already partially oxidized as compared to fats. Hence, combustion of the carbohydrates is a faster process.

Kinetics:

The molecular reacts also shows that the combustion of the carbohydrates is a faster process.

The atomic number of arsenic is 33 what is the electron configuration
rjkz [21]
It is really easy if you look up an electron configuration table (one that looks like a periodic table) and then just go down the rows left to right, top to bottom, and just stop when you get to where the element is on the table.

A balloon has a volume of 6.2 liters at 23.2 C. The balloon is then heated to a temperature of 144.0 C. What is the volume of th
Marina CMI [18]

Answer:

8.7 L

Explanation:

T2(V1/T1) = V2

417.15 K(6.2 L/296.45 K) = 8.7 L

Remember to almost always change celcius to kelvin. Also, this is part of Charle's Law (temp and volume are proportional, so if temp increaces so must the volume or vice versa). Lastly, Charle's Law has the formula of V1/T1 = V2/T2. I just rearranged it to go along with your problem. Hence, the T2(V1/T1) = V2
