The instruction booklet for your pressure cooker indicates that its highest setting is 11.1 psi. You know that standard atmosphe

ric pressure is 14.7 psi, so the booklet must mean 11.1 psi above atmospheric pressure.
At what temperature in degrees Celsius will your food cook in this pressure cooker set on "high"?

<u>Answer:</u> The temperature in the pressure cooker set on high is 206.14°C

<u>Explanation:</u>

STP conditions:

Pressure = 14.7 psi

Temperature = 273 K

To calculate the final temperature of the system, we use the equation given by Gay-Lussac Law. This law states that pressure of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

\frac{P_1}{T_1}=\frac{P_2}{T_2}

where,

P_1\text{ and }T_1 are the initial pressure and temperature of the gas.

P_2\text{ and }T_2 are the final pressure and temperature of the gas.

We are given:

P_1=14.7psi\\T_1=273K\\P_2=(14.7+11.1)psi=25.8psi\\T_2=?

Putting values in above equation, we get:

\frac{14.7psi}{273K}=\frac{25.8psi}{T_2}\\\\T_2=\frac{25.8\times 273}{14.7}=479.14K

Converting the temperature from kelvins to degree Celsius, by using the conversion factor:

T(K)=T(^oC)+273

479.14=T(^oC)+273\\\\T(^oC)=(479.14-273)=206.14^oC

Hence, the temperature in the pressure cooker set on high is 206.14°C

Identify the NMR term that corresponds to each description.
balandron [24]

Answer:

A- upfield

B- down field

C- splitting

D- chemical shift

E- integration

Explanation:

NMR is a spectroscopic technique commonly used to observe the magnetic fields around the nucleus of atoms in a compound under investigation.

A chemical shift is the difference in parts per million (ppm) between the resonance frequency of the observed protons in the compound under study and that of the tetramethylsilane (TMS) (the reference compound in NMR with a chemical shift of zero ppm because all protons in the compound are equivalent).

If signals appear close to the reference signal, the signals are said to appear upfield. If the signals appear far away from the reference, they are said to appear down field.

The presence of protons cause splitting of peaks to the magnitude of n+1. n is the number of neighboring protons. Splitting refers to the appearance of multiple peaks for a single nucleus due to neighboring nuclei.

The area of a signal that corresponds to the number of nuclei at that frequency is called the integration.

Artemon [7]
The total mass of the products is 10.76 g + 204.44 g = 215.20 g.
The masses of all the reactants but one are known so,

215.20 g - 120.00 g - 8.15 g - 75.00 g = 12.05 g

12.05 g is the mass of the unweighed barium nitrate.
