Answer:
Explanation: A compound with the empirical formula SO has a molecular weight of 96.13
When 1 mole of Zn and 2 mole of O₂ reacts togethor, It will produce 1 mole of ZnO as O₂ is excess reagent and Zn will act as Limiting reagent and thus it limits the amount of product formed.
<h3>What is Limiting reagent ?</h3>
Limiting reagents are the substances that are completely consumed first in a chemical reaction.
Given ;
- Amopunt of Zn : 1 mole
- Amount of O₂ : 2 mole
Given equation ;
2Zn + O₂ --> 2ZnO
As according to given chemical equation,
2 moles Zn of reacts with 1 mole of O₂ to produce 2 moles of ZnO.
Therefore,
1 mole of Zn will require 0.5 mole of O₂.
But,
the given amount of O₂ is 2 mole which is excess
Hence,
Zn here will act as the Limiting reagent, According to which the amount of product formed will be decided.
Therefore,
If 2 mole Zn produces : 2 moles of ZnO (According to given balanced equation)
Thus,
1 mole of Zn will produce = 2/2 x 1
= 1 mole of ZnO
Hence, When 1 mole of Zn and 2 mole of O₂ reacts togethor, It will produce 1 mole of ZnO as O₂ is excess reagent and Zn will act as Limiting reagent and thus it limits the amount of product formed.

Answer:
The enthalpy of the reaction is –184.6 kJ, and the reaction is exothermic.
Explanation:
<h2>Let us study about boiling point </h2>
Explanation:
Boiling point
It is the temperature at which liquid changes into gaseous state .
or it can be defined as :
the temperature at which the vapor pressure of a liquid becomes equals to atmospheric pressure .
It depends upon many factors :
- Temperature
- Pressure
- Inter molecular forces present
- Environmental pressure or vapor pressure
Temperature : more is the temperature , more is the vapor pressure hence more is the boiling point .
Pressure : More is the pressure , ore is the boiling point or vice versa .
Intermolecular forces in particles of matter : more are the forces , less is the boiling point as they will have no escaping tendency .
The boiling point of water is : 100 degree celsius
