Explanation:

binding energy, amount of energy required to separate a particle from a system of particles or to disperse all the particles of the system. Binding energy is especially applicable to subatomic particles in atomic nuclei, to electrons bound to nuclei in atoms, and to atoms and ions bound together in crystals.

A sample of gas has an initial volume of 3.00 L and an initial pressure of 2.14 atm. If the volume expands to 8.15 L, what is th

Alla [95]

Answer:

The final pressure is 0.788 atm (option b).

Explanation:

Boyle's law says that the volume occupied by a given gaseous mass at constant temperature is inversely proportional to pressure. That is: if the pressure increases, the volume decreases, while if the pressure decreases, the volume increases. This is expressed mathematically as the product of pressure times volume equal to a constant value:

P*V=k

Assuming a certain volume of gas V1 that is at a pressure P1 at the beginning of the experiment, by varying the volume of gas to a new value V2, then the pressure will change to P2, and it will be fulfilled:

P1*V1=P2*V2

In this case:

P1= 2.14 atm
V1= 3 L
P2= ?
V2= 8.15 L

Replacing:

2.14 atm*3 L= P2* 8.15 L

Solving:

$\frac{2.14 atm*3 L}{8.15 L} =P2$

0.788 atm= P2

<u><em>The final pressure is 0.788 atm (option b).</em></u>

P4010

ludmilkaskok [199]

Answer:

32.76mole of P

Explanation:

The reaction expression is given as;

P₄O₁₀ → 4P + 5O₂

Given parameters:

Number of moles of P₄O₁₀ = 8.19mol

Unknown:

Number of moles of P produced = ?

Solution:

From the balanced reaction expression;

1 mole of P₄O₁₀ will produce 4 mole of P

8.19mole of P₄O₁₀ will therefore produce 4 x 8.19 = 32.76mole of P
