Chemistry
1 answer:
belka [17]3 years ago
3 0

Answer:

CERN uses a series of particle accelerators to accelerate protons to their end speeds in the LHC. The first accelerator is the linear accelerator Linac 2. At one end of Linac 2, hydrogen from a bottle is passed through an electric field to strip off the electrons, leaving positively charged protons.

What is true about a block of ice at -10 degrees celsius as you continue to apply heat...
Y_Kistochka [10]

A. Its temperature will rise continuously until it completely melts

I don't believe that any of the other answers are correct because the ice cannot stay at a certain temperature if it is melting.

Which statements are true?
schepotkina [342]

Explanation:

  • Evaporation is defined as a process in which liquid state of water is changing into vapor state.

So, we need to break the bonds of liquid substance in order to convert it into vapor state. And, energy is absorbed for breaking of bonds which means that evaporation is an endothermic process.

Hence, the statement evaporation of water is an exothermic process is false.

  • When a hydrocarbon reacts with oxygen and leads to the formation of carbon dioxide and water then this type of reaction is known as combustion reaction.

A combustion reaction will always release heat energy. Hence, combustion reaction is exothermic in nature.

  • When energy is transferred as heat from the surroundings to the system then it means energy is being absorbed by the system. And, absorption of heat is an endothermic process for which \Delta H is positive.
  • Whereas when energy is transferred from system to the surrounding then it means energy is released by the system which is an exothermic process.

Hence, for an exothermic process value of \Delta H is negative.

Thus, we can conclude that statements which are true are as follows.

  • A combustion reaction is exothermic.
  • When energy is transferred as heat from the system to the surroundings, \Delta H is negative.
  • For an endothermic reaction Deta H is positive.

State Henry's law. Give an example of Henry's law.
ruslelena [56]

Answer:

Found this off of google, "Henry's law comes into play every time a bottle of Pepsi (or any other carbonated drink) is opened. The gas above the unopened carbonated drink is usually pure carbon dioxide, kept at a pressure which is slightly above the standard atmospheric pressure."
