Answer:Hence, the bond length in HCl is 125 pm.
Explanation:
Bond length : It is an average distance between the nuclei of two bonded atoms in a molecule.
Also given that bond length is the distance between the centers of two bonded atoms. on the potential energy curve, the bond length is the inter-nuclear distance between the two atoms when the potential energy of the system reaches its lowest value. Beyond this if atoms come closer to each other then their will be repulsion between them.
So, the bond length between the Hydrogen and Chlorine atom in HCl molecule is :
Hence, the bond length in HCl is 125 pm.
Answer : The correct option is, 
Explanation :
The conversion used for the temperature from Fahrenheit to degree Celsius is:
where,
= temperature in Fahrenheit
= temperature in centigrade
The conversion used for the temperature from degree Celsius to Kelvin is:
where,
= temperature in Kelvin
= temperature in centigrade
As we are given the temperature in Fahrenheit is, -10
Now we have to determine the temperature in degree Celsius.
Now we have to determine the temperature in Kelvin.
Therefore, the temperature in degree Celsius and Kelvin are,
Moles of Carbon dioxide : 0.75
<h3>Further explanation</h3>
Given
23 g C₃H₈O₃
Required
Moles of Carbon dioxide
Solution
Reaction
2C₃H₈O₃ + 7O₂ → 6CO₂ + 8H₂O
mol C₃H₈O₃ :
= mass : MW
= 23 g : 92,09382 g/mol
= 0.24975
From the equation, mol ratio of C₃H₈O₃ : 3CO₂ = 1 : 3, so mol CO₂ :
= 3/1 x mol C₃H₈O₃
= 3/1 x 0.24975
= 0.74925≈0.750 mol
Driving water out of crystals are crystallization process.
The piece of equipment used are evaporating dish.
Explanation:
Crystallization process
- Crystallization is a process of converting crystalline solid state into liquid state.
- It works both in purification and separation step.
- Steps involved in the crystallization process are
a) Nucleation
b) Crystal growth
- It is the oldest unit operation methods.
- Methods involved in this process are solvent evaporation, slow cooling, solvent diffusion and sublimation.
Evaporating dish
- Evaporating dish is a shallow open container.
- Evaporating dish is used to heat and evaporate solids.
- It is made by borosilicate glass or porcelain, which is non-reactive and withstand heat from Bunsen burner.
