ethyl chloride, c2h5cl, is used as a local anesthetic. it works by cooling tissue as it vaporizes; its heat of vaporization is 2
Inessa [10]

The amount of heat that could be removed by 20.0 g of ethyl chloride is 8.184 kJ.

<h3>How do we calculate required heat?</h3>

Required amount of heat which can be removed for the vaporization will be calculated as:

Q = (n)(ΔHv), where

  • n = moles of ethyl chloride
  • ΔHv = heat of vaporization = 26.4 kj/mol

Moles will be calculated as:

n = W/M, where

  • W = given mass of ethyl chloride = 20g
  • M = molar mass of ethyl chloride = 64.51 g/mol

n = 20 / 64.51 = 0.31 mol

On putting all these values in the above equation, we get

Q = (0.31)(26.4) = 8.184 kJ

Hence involved amount of heat is 8.184 kJ.

When placed between oppositely charged metal plates, the region of a water molecule attracted to the negative plate is the *blan
Gala2k [10]

Answer : The correct option is (A) Hydrogen region of the molecule.

Explanation :

As we know that the water molecule has two hydrogen atom and one oxygen atom. The hydrogen atom has partial positive charge and oxygen has partial negative charge.

In the charged plate, the negative attracts positive and positive attracts negative. So, the hydrogen atom attracted to the negative plate and the oxygen atom attracted to the positive plate.

When water molecule placed between oppositely charged metal plates which is positively charged, then the hydrogen atom which is positively charged attracted towards the negative plate.
