A chemical engineer must calculate the maximum safe operating temperature of a high-pressure gas reaction vessel. The vessel is

a stainless-steel cylinder that measures 26.0cm wide and 31.2cm high. The maximum safe pressure inside the vessel has been measured to be 6.40MPa. For a certain reaction the vessel may contain up to 1.19kg of dinitrogen difluoride gas. Calculate the maximum safe operating temperature the engineer should recommend for this reaction. Write your answer in degrees Celsius. Round your answer to 3 significant digits.

Answer: The destruction of crust occurs at deep-sea trenches. Oceanic rocks are pillow-shaped when formed. Rocks across the ocean floor have alternating magnetic stripes. Younger rocks are closer to mid-ocean ridges.

8. Determine the number of significant figures in the following numbers
sweet [91]

Answer:

a) 5

b) 4

c) 3

d) 3

e) 4

Explanation:

I use only one rule when the decimal is present, meaning you can see the decimal (as is the case with all of these).

When the decimal is Present, start counting sig figs from the Pacific (left) side of the number beginning with the first non-zero digit and count all the way to the end.

So, for example, in "a", the first non-zero digit starting from the left is 1, then continue counting all the way to the right side.

For "c",  the first non-zero digit is the left most 4 (skip the first 4 zeros), then count all the way to the right side.

2 A certain gas of 25 g at 25°c and 0.65 atm occupies a volume of 23.52L Determine the molecule mass of the gas.​
denpristay [2]

Answer:

{ \bf{PV= \frac{m}{M} RT}} \\  \\ { \tt{(0.65  \times 23.52)  =  \frac{25}{M}  \times 0.081 \times (25 + 273)}} \\  \\ M = 39.5 \: g

Using the ideas from this section and the periodic table, choose the more reactive nonmetal.
fiasKO [112]

O

Explanation:

Oxygen is a more reactive non-metal.

There are several parameters to test how reactive an element is. In this case, we are going to use the electronegativity of the two atoms.

  • Electronegativity is the relative tendency with which atoms of the element attract valence electrons in a chemical bond.

A high electronegativity value suggests more reactivity and a low value implies low reactivity.

On the Pauling's Eelectronegativity table, Oxygen has a value of 3.5 and Phosphorus has 2.1

It implies that oxygen is a more reactive non-metal compared to phosphorus.

An alkene adds hydrogen in the presence of a catalyst to give 3,4-dimethylhexane. Ozonolysis of the alkene followed by treatment
slamgirl [31]

The structure of alkene is given below in the image.

Alkenes are described as both branched or unbranched hydrocarbons that possess at least one carbon-carbon double bond (CC) and feature a popular system of CnH2n [1].

Alkanes are organic compounds that encompass single-bonded carbon and hydrogen atoms. The formulation for Alkanes is CnH2n+2, subdivided into 3 companies – chain alkanes, cycloalkanes, and branched alkanes.

The geometry around each carbon atom is based totally on a trigonal planar shape, due to the fact, that each carbon has three electrons around it. This must make the angle of each bond one hundred twenty.

A sample of O2(g) is placed in an otherwise empty, rigid container at 4224 K at an initial pressure of 4.97 atm, where it decomp
frutty [35]

Answer:

The value of K_p at 4224 K is 314.23.

Explanation:

O_2(g)\rightleftharpoons 2O(g)

Initially

4.97 atm            0

At equilibrium

4.97 - p               2p

At initial stage, the partial pressure of oxygen gas = =4.97 atm

At equilibrium, the partial pressure of oxygen gas = p_{O_2}=0.28 atm

So, 4.97 - p = 0.28 atm

p = 4.69 atm

At equilibrium, the partial pressure of O gas = p_{O}=2p=2\times 4.69 atm=9.38 atm

The expression of K_p is given as :

K_p=\frac{(p_{O})^2}{(p_{O_2})}

K_p=\frac{(9.38 atm)^2}{0.28 atm}=314.23

The value of K_p at 4224 K is 314.23.
