A sample of gas contains 0.1100 mol of HBr(g) and 5.00x10^-2 mol of Cl2(g) and occupies a volume of 5.85 L. The following reacti
Vesna [10]

The volume of the sample after the reaction : V₂=5.484 L

<h3>Further explanation</h3>

Given

Reaction

2HBr(g) + Cl2(g) => 2HCl (g)+Br2(g)

0.1100 mol of HBr(g)

5x10⁻² mol of Cl2(g)

Required

The volume of the sample after reaction

Solution

Find limiting reactant :

0.11/2 : 0.05/1 = 0.055 : 0.05

Limiting reactant : Cl₂

mol Products based on mol Cl₂

mol products = mol HCl + mol Br₂

mol products = 2/1x0.05 + 1/1x0.05

mol products = 3 x 0.05 = 0.15

mol reactants = 0.11 + 0.05 = 0.16

<em>From Avogadro's law, </em>

In the same T, P, and V, the gas contains the same number of molecules  

So the ratio of gas volume will be equal to the ratio of gas moles  

 V₁/n₁=V₂/n₂

1 = reactants, 2 = products

Input the value :

5.85/0.16=V₂/0.15

V₂=5.484 L

The tallest mast in the world is the KTHI-TVmast in Branchard, which measures 2063 feet , what is the expressed in meter?
Amanda [17]
1ft=.3048meter

So if we have 2063ft and want it in meters we just do a simple unit conversion.

(2063ft)(.3048meters/1ft)=628.8meters. Here ft cancel out and leave us with meter units.

Any questions please feel free to ask. Thank you.

Why was it important to polish the copper strips and wire, the coin, and the nail in the electroplating experiment?
Ierofanga [76]

Answer:

You need to have a clean surface for contact between the solution and the material.

Explanation:

The presence of impurity on the surface of the material, and lack of surface uniformity (smoothness) can reduce the effective contact between material and solution and can interfere with the electroplating process's success.
