At 570 mm hg and 25 c a gas sample has a volume of 2270 ml what is the final pressure at a volume of 1250 ml?
ValentinkaMS [17]

Main Answer:

Given data:

Initial Pressure P1 = 570 mm hg

Initial Volume V1 = 2270 ml

Final Pressure P2 = ? mm hg

Final Volume V1 = 1250 ml

According to the ideal gas equation,

PV = constant.

P1V1 = P2V2

P2 = P1V1/V2

P2 = (570 x 2270) / 1250

P2 = 1035.12 mm hg

The final pressure at volume of 1250 ml is 1035.12 mm hg.

Explanation:

What is ideal gas equation ?

The ideal gas equation is as follows:

PV = nRT

where P = Pressure

V = Volume

n = number of moles of gas

R = Universal gas constant

T = Temperature

This ideal gas equation provides the macroscopic particles behavior of the gas. At this condition, the particles of the gas, won't be attract or repel each other. It is consider as the stable condition.

Calculate the mole fraction of each component in a solution of 42 g CH3OH, 35 g of chloroform CHCl3, and 50 g C3H7OH
koban [17]

Considering the definition of mole fraction, the mole fraction of each component in the solution is:

  • CH₃OH: 0.54
  • CHCl₃: 0.118
  • C₃H₇OH: 0.342

<h3>Mole fraction</h3>

The molar fraction is a way of measuring the concentration that expresses the proportion in which a substance is found with respect to the total moles of the solution.

<h3>Mole fraction of each component</h3>

In this case, in first place you should know that the molar mass of each component is:

  • CH₃OH: 32 \frac{g}{mole}
  • CHCl₃: 121.35 \frac{g}{mole}
  • C₃H₇OH: 60 \frac{g}{mole}

Now, the number of moles of each compound can be calculated as:

  • CH₃OH: \frac{42 g}{32\frac{g}{mole}}=  1.3125 moles
  • CHCl₃: \frac{35 g}{121.35\frac{g}{mole}}= 0.2884 moles
  • C₃H₇OH: \frac{50 g}{60\frac{g}{mole}}=  0.8333 moles

So, the total moles of the solution can be calculated as:

Total moles = 1.3125 moles + 0.2884 moles + 0.8333 moles

<u><em>Total moles = 2.4342 moles</em></u>

Finally, the more fraction of each component can be calculated as follow:

  • CH₃OH: \frac{1.3125 moles}{2.4342 moles}= 0.54
  • CHCl₃: \frac{0.2884 moles}{2.4342 moles}= 0.118
  • C₃H₇OH: \frac{0.8333 moles}{2.4342 moles}= 0.342

In summary, the mole fraction of each component in the solution is:

  • CH₃OH: 0.54
  • CHCl₃: 0.118
  • C₃H₇OH: 0.342

How many covalent bonds does nitrogen form if each of its unpaired electrons participate in one bond?
nirvana33 [79]

Nitrogen could form 3 covalent bonds if each of its unpaired electrons participates in one bond.

Nitrogen atom forms 3 bonds based on octet rule, because it has 5 valence electrons. That means it needs 3 bonds or three more electrons.

<h3>Further Explanation;</h3><h3>Chemical bond  </h3>
  • A bond is a type of force that is formed between atoms of different through the sharing or transfer of electrons.
<h3>Octet rule</h3>
  • According to the octet rule for an atom to be stable it must have maximum number of electrons in its outermost energy level. Therefore an atom with four electrons requires four more electrons to attain stability.
<h3>Types of chemical bonds.</h3><h3>Covalent bond  </h3>
  • This is a type of bond that is formed between non-metal atoms. It is formed as a result of sharing electrons between non-metal atoms involved.
  • When atoms involved contribute equal number of electrons to the bond formation, the type of bond is known as covalent bond
  • A covalent bond may be a dative covalent bond, when the shared electrons come from one atom.
<h3>Ionic bond  </h3>
  • This is a type of bond that occurs between metal ions and non-metal ions. Ionic bond occurs as a result of transfer of electrons from one metal atom to another non-metal atom.
  • After the transfer of electrons, metal atom loses electron to form a cation while the non-metal atom gains electrons to form an anion.
<h3>Other types of chemical bonds include;</h3>
  • Hydrogen bonds
  • Metallic bonds
  • Dipole-dipole interactions, etc.

Keywords: Chemical bond, covalent bond, atom
