How can you determine the specific heat of a metal using a calorimeter? make a hypothesis
Sever21 [200]

Answer:

One can determine the specific heat of the metal through using the clarimeter, water, thermometer and using heat equations.

Explanation:

You can learn about heat effects and calorimetery through a simple experiment by boiling water and heating up the metal in it. Then, pour it into your calorimeter and the heat will flow from the metal to the water. The two equlibria will meet: the metal will loose heat into its surroundings (the water) and teh water will absorb the heat. The heat flow for the water is the same as it is for the metal, the only difference being is the negative sign indicating the loss of the heat of the metal.

In terms of theromdynamics, we can deteremine the heat flow for the metal becasue it would be equal to the mangnitued but opposite in direction. Thus, we can say that the specific heat of water qH2O = -qmetal.

F2 + 2HCl + Cl2 + 2HF I need help what are the answers to these questions?
Anon25 [30]

In the given reaction  fluorine is reduced and chlorine is oxidized.

<h3>What is oxidation and reduction?</h3>

Oxidation is a process in which addition of oxygen or removal of hydrogen and electron takes place, while reduction is a process in which addition of hydrogen & electrons or removal of oxygen takes place.

Given chemical reaction is:

F₂ + 2HCl → Cl₂ + 2HF

  • In the above reaction fluorine is reduced as it accepts an electron and increase in it its oxidation state takes from 0 to -1, which shows reduction.
  • In the reaction chlorine is oxidized as it losses an electron and decrease in its oxidation state takes from -1 to 0, which shows oxidation.
  • Oxidation half reaction is:

F₂ + 2e⁻ → 2F⁻

  • Reduction half reaction is:

2Cl⁻ → Cl₂ + 2e⁻

Hence, fluorine is reduced and chlorine is oxidized in the given reaction.
