What is the formula equation for the reaction between sulfuric acid and dissolved sodium hydroxide if all products and reactants
2 answers:
Explanation:
Reactants are the species that are present on left hand side of a chemical reaction. Whereas products are the species that are present on right hand side of a chemical reaction.
For example,
Here, both sulfuric acid and sodium hydroxide are the reactants. On the other hand, both water and sodium sulfate are the products.

<u>Answer:</u> The value of work for the system is -935.23 J
<u>Explanation:</u>
To calculate the number of moles, we use the equation:
Given mass of sodium azide = 16.5 g
Molar mass of sodium azide = 65 g/mol
Putting values in above equation, we get:
The given chemical equation follows:
By Stoichiometry of the reaction:
2 moles of sodium azide produces 3 moles of nitrogen gas
So, 0.254 moles of sodium azide will produce = of nitrogen gas
To calculate volume of the gas given, we use the equation given by ideal gas, which follows:
where,
P = pressure of the gas = 1.00 atm
V = Volume of the gas = ?
T = Temperature of the gas =
R = Gas constant =
n = number of moles of nitrogen gas = 0.381 moles
Putting values in above equation, we get:
To calculate the work done for expansion, we use the equation:
We are given:
P = pressure of the system = (Conversion factor: 1 atm = 101325 Pa)
= change in volume =
(Conversion factor:
)
Putting values in above equation, we get:
Hence, the value of work for the system is -935.23 J
The carbocation stabilized by resonance structure and thereby lowers the energy of the carbocation, hydrogen will add to the carbon in the double bond that produces delocalization of electrons.
<h3>What is carbocation?</h3>A carbocation is a molecule in which a carbon atom has a positive charge and three bonds.
In general, electrons are stabilized by delocalization. The stabilization energy engendered by delocalization over more than two atoms is called the resonance stabilization energy or simply the resonance energy. The greater the extent of electron delocalization the greater the resonance stabilization.
