Sveta_85 [38]3 years ago
5 0

Answer:

4.0 moles

Explanation:

The following data were obtained from the question:

Volume (V) = 12L

Pressure = 5.6 atm

Temperature (T) = 205K

Gas constant (R) = 0.08206 atm.L/Kmol

Number of mole (n) =?

Using the ideal gas equation: PV = nRT, the number of mole of the gas can be obtained as follow

PV = nRT

5.6 x 12 = n x 0.08206 x 205

Divide both side by 0.08206 x 205

n = (5.6 x 12)/(0.08206 x 205)

n = 4.0 moles

Therefore, the number of mole of the gas is 4.0 moles

What letter represents the activation energy for the reverse reaction?
Bezzdna [24]

<u>Answer:</u> The correct answer is Option 4: U

<u>Explanation:</u>

Activation energy is defined as the energy that is given to a chemical system with potential reactants to produce products. It is represented as E_{ac}

It is represented as the energy from the reactants to the activated complex.

Reverse reaction is defined as the reaction in which the products formed become reactants and leads to the formation of reactants back.

So, here, the activation energy of the reverse reaction is the energy between the products and the activated complex, which is represented as letter U in the given graph.

Hence, the correct answer is Option 4: U

What is the mass percentage of oxygen in Ba3(PO4)2? Please help how do I go about figuring this out?
Mice21 [21]

Molecular Mass of Compound.

\\ \sf\longmapsto Ba_3(PO_4)_2

\\ \sf\longmapsto 3(137u)+2(39u+4(16u))

\\ \sf\longmapsto 411u+2(39u+64u)

\\ \sf\longmapsto 411u+2(103u)

\\ \sf\longmapsto 411u+206u

\\ \sf\longmapsto 617u

  • Molecular mass of O in compound=16(4)=64u

\\ \sf\longmapsto Mass\%\:of\:O

\\ \sf\longmapsto \dfrac{64}{617}\times 100

\\ \sf\longmapsto \dfrac{6400}{617}

\\ \sf\longmapsto 10.3\%

DiKsa [7]

Answer:

Cl

Explanation:

n for Mg=m:Mm

=65.8:24

=2.74mol

n for Cl=m:Mm

=45.7:70

=0.65mol

According to the <em>number of moles</em> we can say that the limiting reagent is Cl as it has few moles.
