Answer:

Reaction equilibrium will shift to the left (higher molar volume side of process).

Explanation:

For gas phase reactions, changes in pressure-volume conditions cause a stress on the process equilibrium shifting away from the applied pressure-volume change.

LeChatlier's Principle states for a gas phase reaction at equilibrium ...

if the pressure is increased (volume decreased) the reaction will shift toward the lower molar volume side of the process.

if the pressure is decreased (volume increased) the reaction will shift toward the higher molar volume side of the process.

if the sum of molar volumes of reactants equals the sum of molar volumes of products, changes in pressure-volume conditions will NOT affect the equilibrium stability. Example => H₂(g) + Cl₂(g) ⇄ 2HCl(g) will not be affected by P-V changes as ∑Vm(reactants) = ∑Vm(products).

Diborane (B2H6) has been considered as a possible rocket fuel. Calculate DH° for the reaction B2H6(g) ---> 2B(s) + 3H2(g) usi

svlad2 [7]

Answer:

A. DH° = –36 kJ

Explanation:

It is possible to obtain DH° of a reaction by the sum of DH° of half reactions. The DH° of the reaction:

B₂H₆(g) → 2B(s) + 3H₂(g)

Could be obtained from:

<em>(1) </em>2B(s) + 1.5O₂(g) → B₂O₃(s) DH° = –1273kJ

<em>(2) </em>B₂H₆(g) + 3O₂(g) → B₂O₃(s) + 3H₂O(g) DH° = –2035kJ

<em>(3) </em>H₂(g) + 0.5O₂(g) → H₂O(g) DH° = –242kJ

The sum of (2) - (1) gives:

B₂H₆(g) + 1.5O₂(g) → 2B(s) + 3H₂O(g) DH° = -2035kJ - (-1273kJ) = -762kJ

Now, this reaction - 3×(3):

B₂H₆(g) → 2B(s) + 3H₂(g) DH° = -762kJ - (3×-242kJ) = -36kJ

Thus, right answer is:

An object will _____ if the weight of the liquid displaced is less than the weight of the object.

Tpy6a [65]

I am not exactly sure the answer that you are looking for, but I will guess on what you might be looking for. If the weight of an object is greater than the weight of the liquid it's being put into, the object will sink. Although, it isn't necessarily just based upon weight, it is more dependent on density to decide if it'll float or sink.

K-40 is a radioactive isotope of potassium that undergoes beta decay. What is the product of this decay

Aleks [24]

Answer:

⁴⁰₂₀Ca + ⁰₋₁e

Explanation:

Beta decay:

Beta radiations are result from the beta decay in which electron is ejected. The neutron inside of the nucleus converted into the proton an thus emit the electron which is called β particle.

Properties of beta radiations:

The mass of beta particle is smaller than the alpha particles.

They can travel in air in few meter distance.

These radiations can penetrate into the human skin.

The sheet of aluminium is used to block the beta radiation

⁴⁰₁₉K → ⁴⁰₂₀Ca + ⁰₋₁e

The beta radiations are emitted in this reaction. The one electron is ejected and neutron is converted into proton.

Write a chemical equation for the acid-base reaction that occurs when p-phenetidine is dissolved in hcl. why is

melisa1 [442]

<h3><u>Answer;</u></h3>

EtO-PHE-NH2 + H+ _______ EtO-PHE-NH3+ Cl-

<h3><u>Explanation;</u></h3>

<em><u>p-phenetidine is p-ethoxy aniline so the amino group acts as a base. The free electron pair on nitrogen will form a coordinate covalent bond with the H+ from the ionized HCl. </u></em>
HCl is used for the acid-base reaction in p-phenetidine in amide synthesis of acetophenetidin rather than water becuase HCl's polarity contributes to a reaction driven to the right. It protonates the amine group, making it easy to dissolve.

A cylinder contains water to a level of 15.5. 20.0 grams of copper is dropped in. What will be the new height of the water? (Den

Julli [10]

The new height of the water is 17.7 mL

The density of a substance is simply defined as mass per unit volume of the substance. Mathematically, it is expressed as:

<h3>Density = mass / volume </h3>

With the above formula, we can obtain the volume of the copper. This can be obtained as follow:

Mass of copper = 20 g

Density of copper = 8.96 g/mL

<h3>Volume of copper =?</h3>

Density = mass / volume

8.96 = 20 / volume

Cross multiply

8.96 × Volume = 20

Divide both side by 8.96

Volume = 20 / 8.96

<h3>Volume of copper = 2.2 mL</h3>

Finally, we shall determine the new height of the water. This can be obtained as follow:

Initial height of water = 15.5 mL

Volume of copper = 2.2 mL

<h3>New height of water =?</h3>

<h3>New height of water = (Initial height of water) + (Volume of copper)</h3>

New height of water = 15.5 + 2.2

<h3>New height of water = 17.7 mL</h3>

Therefore, the new height of the water is 17.7 mL
