Convert a pressure of 0.0248 mm Hg to the equivalent pressure in pascals (Pa).

Chemistry
1 answer:
drek231 [11]1 year ago
5 0

Answer is 3.306 Pa.


<em>Explanation:</em>


This is a simple unit conversion problem.

1 atm = 760 mmHg = 101325 Pa


Hence,

    0.0248 mmHg = (101325 Pa / 760 mmHg) x 0.0248 mmHg

                           = 3.306 Pa


Pressure can be measured by using many units such as atm, Pa, torr, bar, cmHg, mmHg and so on.


The relationships among those units as follows

1 atm = 101325 Pa = 1.01325 bar = 760 torr, 760 mmHg = 76 cmHg

Scientists determine that the wooden beams of a sunken ship have 67 % of the concentration of Carbon-14 that is found in the lea
DerKrebs [107]

Answer:

The age of ship is 1900 years.

Explanation:

The half life period of carbon - 14 is 5730 years

Ship have 67 % of the concentration of Carbon-14

And the ship lost (100- 67 = 33%) 33% of carbon - 14.

Therefore,

The age of ship = lost percentage X half life period of carbon -14

= 33 \times 5730 yrs = 1890.9yrs\equiv 1900\,years

Therefore, The age of ship is 1900 years.

Methylene chloride (CH2Cl2) has fewer chlorine atoms than chloroform (CHCl3). Nevertheless, methylene chloride has a larger mole
icang [17]

Answer:

Explanation has been given below.

Explanation:

  • Chloroform has three polar C-Cl bonds. Methylene chloride has two polar C-Cl bonds. So it is expected that chloroform should be more polar and posses higher dipole moment than methylene chloride.
  • Two factors are liable for the opposite trend observed in dipole moments of methylene chloride and chloroform.
  • First one is the number of hyperconjugative hydrogen atoms present in a molecule. Hyperconjugation occurs with vacant d-orbital of Cl atom. Hyperconjugation amplifies charge separation in a molecule resulting higher dipole moment.
  • Methylene chloride has two hyperconjugative hydrogen atoms and chloroform has one hyperconjugative hydrogen atom.Therefore methylene chloride should have higher charge separation as compared to chloroform.
  • Second one is induction of opposite polarity in a C-Cl bond by another C-Cl bond in a molecule. Higher the opposite induction of polarity, lower the charge separation in a molecule and hence lower the dipole moment of a molecule.
  • Chloroform has three C-Cl bonds and methylene chloride has two C-Cl bonds. Therefore opposite induction is higher for chloroform resulting it's lower dipole moment.

In the reaction of nitrogen gas with oxygen gas to produce nitrogen oxide, what is the effect of adding more oxygen gas to the i
Alborosie
<h3>Answer:</h3>

The Equilibrium would shift to produce more NO

<h3>Explanation:</h3>

The reaction is;

N₂(g) + O₂(g) ⇆ 2NO(g)

  • When a reaction is at equilibrium then the forward reaction rate will be equivalent to the reverse reaction rate. Additionally, the concentration of the reactants and products are the same.
  • From Le Chatelier's principle, additional reactants favor the formation of more products while additional products favor the formation of more reactants.
  • For example, when more oxygen is added then more Nitrogen (II) oxide will be formed.
  • Oxygen is a reactant and when increased it favors forward reaction which leads to the formation of more NO which is the product.
