<u>Given:</u>

Kp = 1.5*10³

partial pressure pN2 = 0.10 atm

partial pressure pH2 = 0.15 atm

<u>To determine:</u>

Partial pressure pNH3 at equilibrium

<u>Explanation:</u>

The decomposition reaction is:-

2NH3(g) ↔N2(g) + 3H2(g)

Kp = [pH2]³[pN2]/[pNH3]²

pNH3 =√ [(pH2)³(pN2)/Kp]

pNH3 = √(0.15)³(0.10)/1.5*10³ = 4.74*10⁻⁴ atm

Ans (a)

2HgO—&gt;2Hg+O2. I start with 46.8 g HgO. What is my theoretical yield of O2?
jok3333 [9.3K]

Answer:

Theoretical yield = 3.52 g

Percent yield =65.34%

Explanation:

Given data:

Mass of HgO = 46.8 g

Theoretical yield of O₂ = ?

Percent yield of O₂ = ?

Actual yield of O₂ =  2.30 g

Solution:

Chemical equation:

2HgO  →   2Hg + O₂

Number of moles of HgO = mass/ molar mass

Number of moles of HgO = 46.8 g / 216.6 g/mol

Number of moles of HgO = 0.22 mol

Now we will compare the moles of HgO with oxygen.

                         HgO             :             O₂

                             2               :               1

                            0.22           :          1/2×0.22 = 0.11 mol

Theoretical yield:

Mass of oxygen = number of moles × molar mass

Mass of oxygen =  0.11 mol × 32 g/mol

Mass of oxygen = 3.52 g

Percent yield :

Percent yield = actual yield / theoretical yield × 100

Percent yield = 2.30 g/ 3.52 g × 100

Percent yield =65.34%

Give the formula or name for the following binary acids:
ICE Princess25 [194]

Answer:

Formula and name of the binary acids.

Hydrochloric acid - HCl - Hydrogen chloride

Hydrobromic aci - HBr - Hydrogen bromide.

Explanation:

A substance which produces hydronium ions into water called binary acids.

most of the acids contain hydrogen in their chemical formula.

A binary acid composed of a hydrogen cation bonded to the one other element.

For example, HCl,HF and HI

The name and formula of the given binary acids is as follows.

Hydrochloric acid - HCl - Hydrogen chloride

Hydrobromic aci - HBr - Hydrogen bromide.

The gas in an engine cylinder is compressed until it has a volume of 0.045 liter and an absolute pressure of 28 atmospheres. If
Sonbull [250]

The  temperature  in K  is  767.4 K

<u><em>  calculation</em></u>

This is calculated using the ideal gas equation

that is PV =nRT

where;

P(pressure)= 28 atm

V(volume) = 0.045 L

n(number of moles)= 0.020 moles

R( gas  constant)  =0.0821 L.atm/mol.K

T(temperature)= ? K\


make T the subject of   the formula  by diving  both side of equation by nR

T =PV/nR

T ={ (28 atm x 0.045 L) /( 0.020 mol x 0.0821 L.atm/mol.K)}  =767.4 K
