A student adds hydrobromic acid (HBr) to a solution of sodium bromide at equilibrium. How does this change affect the system?

Chemistry

The addition of bromine would cause the equilibrium to shift towards the reactant's side.

<h3>Equilibrium</h3>

When a reaction is in equilibrium and one of the constraints that affect the rate of reactions is applied, the equilibrium shifts so as to annul the effects of the introduced constraints.

Thus, for the reaction

NaBr(s) ⇌ Na+(aq) + Br−(aq)

The addition of HBr would introduce more Br- into the reaction. Consequently, the equilibrium will shift to produce more NaBr so as to annul the effects of the addition of Br-

What is the empirical formula of propene CH3 CH2 CH2​
kiruha [24]

Answer:

<u>CH</u>

Explanation:

Molecular formula of propene : <u>C₃H₆</u>

Take the HCF of carbon and hydrogen atoms :

  • 3 = 3
  • 6 = 2 x 3

Then, we can write the formula as :

  • 3CH
  • This means there are 3 moles present

Empirical Formula :

  • Molecular Formula / No. of moles
  • C₃H₆ / 3
  • <u>CH</u>

<u></u>

The empirical formula of propene is <u>CH</u>

Analyze the bonds of CCl4. What is the shape of the CCl4 molecule? Is it symmetrical? Does this mean that the CCl4 molecule is p
Crank

C-Cl bond is polar.


As Cl is more electronegative than C,  

Cl pulls the shared electrons towards its side making the C-Cl bond polar.


Polar meaning C gets a partial positive charge and Cl gets a partial negative charge. Thus C-Cl bond becomes polar.


CCl4 molecule is tetrahedral.

And its shape is symmetrical.


That means its similar on all corners or all planes and it can be cut into equal halves from any plane.


C-Cl bond is polar.But the C-Cl polairty gets cancelled out as its pulled equally from all sides.


Since the molecule is symmetrical CCl4 is non polar.

According to the following reaction, how many grams of nitrogen monoxide will be formed upon the complete reaction of 31.0 grams
Mumz [18]

23.227 grams of NO is formed upon the complete reaction of 31.0 grams of oxygen gas with excess ammonia.

Explanation:

The balanced chemical equation is:

4NH3 + 5O2 ⇒ 4NO + 6H20

Number of moles will be calculated.

31 grams of oxygen is given

atomic weight of oxygen gas i.e O2 = 32gm/mole

The molar mass of oxygen gas is 32 grams/mole which is equal to one mole of the molecule.

Number of moles (n) = \frac{mass}{atomic mass of one mole of the substance}

                             n=    \frac{31}{32}

                              n = 0.968 moles of oxygen are given for the reaction to occur.

From the balanced chemical equation it can be seen

5 moles of oxygen yielded 4 moles of NO

So, 0.968 moles of oxygen yield x moles of NO

\frac{4}{5} = \frac{x}{0.968 }

4 × 0.968 =5x

x = 0.774 moles of NO will be formed.

To calculate the mass of NO

mass= atomic mass x number of moles

atomic mass of NO is 30.01 grams/mole

putting the values in the formula:

mass = 30.01 x 0.774

          = 23.227 grams of NO is formed.
