Answer: (a) The products are and AgCl. The balanced equation is .
(b) The type of reaction is double displacement reaction.
Explanation:
(a) The complete reaction equation will be as follows.
Number of atoms on reactant side are as follows.
- Be = 1
- Cl = 2
- Ag = 2
- = 2
Number of atoms present on product side are as follows.
- Be = 1
- Cl = 2
- Ag = 2
- = 2
Here, number of atoms on both reactant and product side are the same. Hence, it is a balanced chemical equation.
(b) A reaction in which two reactant species tend to change their ions with each other and form new compounds. This type of reaction is called double displacement reaction.
As the given reaction is as follows.
This shows that ions are being exchanges by the reactants and
. The ions are , , and .
Therefore, this reaction is a double displacement reaction.
The balanced chemical reaction for the complete combustion of C4H10 is shown below:
C4H10 + (3/2)O2 --> 4CO2 + 5H2O
The enthalpy of formation are listed below:
C4H10: -2876.9 kJ/mol
O2: none (because it is pure substance)
CO2: -393.5 kJ/mol
H2O: -285.8 kJ/mol
The enthalpy of combustion is computed by subtracting the total enthalpy formation of the reactants from that of the products.
ΔHc = (4)(-393.5 kJ/mol) + (5)(-285.8 kJ/mol) - (-2876.9 kJ/mol)
= -<em>126.1 kJ</em>
Thus, the enthalpy of combustion of the carbon is -126.1 kJ.
The condensed structure of given compounds are shown in the below image.
<h3>What is functional group?</h3>
Functional group is the specific group which is present in an organic compound gives information about the properties of that compound.
- In 1,2-propanediol compound hydroxyl functional group is present on the 1st and 2nd position.
- In Ethyl methyl ether, ether functional group is present.
- In Dichloromethane, two atoms of chlorine groups are present.
Hence, structure of the given compounds are shown in the below image.
