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.

The practice of making operations "carbon neutral" is a way to offset whatever damage is being done to the environment due to gr
Marianna [84]

Answer:

True

Explanation:

The greenhouse effect is the process whereby there is radiation from a atmosphere planet and the planet increase the temperature of the planet's surface to a temperature above normal.In this process the Earth's atmosphere becomes thicker with the influence substances such as gases

and the radiation coming from the sun is trapped, then the Earth becomes warmer. Green house effect is seen in global warming.

Carbon neutral can be described as a process of removing huge amount of carbon dioxide from the atmosphere in order to achieve zero carbon neutrality.It is also reffered to as carbon neutrality, and this can be achieved by actions of organizations, businesses and individuals .

Carbon neutral can be achieved in two ways;

: 1.) Maintaining a balance between carbon dioxide emissions and carbon removal by means of the process called carbon offsetting

2 ) the process of removal of carbon dioxide from the atmosphere in order to balance up emissions in another place.

Carbon positive is crucial to increase the positive influence of our daily activities on climate change and our resources.

while reduce the negative effect of our activities and business on evironment.

Therefore, the practice of making operations "carbon neutral" is a way to offset whatever damage is being done to the environment due to greenhouse gas emissions by purchasing credits from "carbon-positive" projects to balance out emissions is true because the harmful gasses that is been released to the atmosphere is balance up by the carbon neutral process hence the reduction in green house effect.

By how much will the water temperature increases if 1046 J of heat energy are added. The specific heat of water is 4.184 J/g • °
Brilliant_brown [7]

Answer:

Option A

250 degrees Celcius

Explanation:

If 1046J of heat energy is added to water, the water will experience a rise in temperature, at a rate that is directly proportional to its specific heat capacity.

Mathematically, this can be seen as Q=C\Delta T

Where C = specific heat of water = 4.184 J/g • °C.

Q = heat energy = 1046 J

\Delta T =1046/4.148=250 degrees Celcius

Therefore, the increase in temperature that will be experienced, is for 250 degrees Celcius

What stress will shift the following equilibrium system to the left?
Alona [7]

<u>Answer:</u> Increasing temperature

<u>Explanation:</u>

The Principle of Le Chatelier states that <u>if a system in equilibrium is subjected to a change of conditions, it will move to a new position in order to counteract the effect that disturbed it and recover the state of equilibrium. </u>

The variation of one or several of the following factors can alter the equilibrium condition in a chemical reaction:

  • Temperature
  • The pressure
  • The volume
  • The concentration of reactants or products

In the case of the reaction in the question, <u>the change that moves the balance to the left will be the one that moves it towards the reagents</u>, that is, that favors the production of reagents instead of products.

  • Decreasing the concentration of SO3 and increasing the concentration of SO2 <u>will favor the production of SO3</u>, which is the product of the reaction.
  • Decreasing the volume increases the pressure of the system and the balance will move to where there is less number of moles. In the case of the reaction in question, we have 3 moles of molecules in the reactants (1 mole of O2 + 2 moles of SO2) while in the products there are 2 moles of SO3 only, therefore, <u>decreasing the volume will displace the balance to the right</u>, which corresponds to the sense in which there is less number of moles.

The reaction of the question is an exothermic since ΔH <0, therefore in the reaction heat is produced and it can be written in the following way,

2SO2(g) + O2(g) ⇌ 2SO3(g) + heat

  • So, if we increase the temperature we will be adding heat to the system, so the balance would move to the left to compensate for the excess heat in the system.
