The front vent of a fume hood that assists and maintain proper air circulation is <u>Airfoil</u>
<u />
The horizontal flat surface area of the fume hood where experiments are being carried out is <u>Work Surface.</u>
<u />
The main characteristics which demonstrate and describes how substances evaporate rapidly and readily into the thin air while producing a huge amount of vapor is known as <u>Volatile</u>
<u></u>
In front of the fume hood, lies the glass panel whose main purpose is to shield the user from the hazardous substance. This glass panel is known as the<u> Sash.</u>

Answer & Explanation:
Kindly find the attached presentation.
When sodium phosphate reacts with sulfuric acid, forming sodium sulfate and phosphoric acid, the stoichiometric coefficient for sulfuric acid in the balanced chemical equation is 3.
In every balanced chemical equation, the total number of individual atoms on the reactant side must be equal to the total number of individual atoms on the product side. The stoichiometric coefficient is the number written in front of each reactants and products that tells how many moles of each are needed in the reaction.
The chemical equation for the given reaction is:
+ 
= 
+ 
Put the necessary stoichiometric coefficient to balance each element.
Balancing Na:
+ = 
+
Balancing P:
+ = + 
Balancing S:
+ 
= +
Notice that H and O are already balanced.
Hence, the balanced chemical equation for the reaction is:
+ = +
where 3 is the stoichiometric coefficient of sulfuric acid, .

Using Daltons Law which states that the total pressure of a gas mixture is the sum of the gasses partial pressure.Thus,
Pt(total pressure)= P1+P2+P3
where
Pt= 0.90 atm
P1= 0.26 atm
P2 = 0.28 atm
P3 = ?
substitute the formula with known variables
P3= 0.90 atm-(0.26atm+0.28atm)
P3 = 0.36 atm
The partial pressure of ammonia is 0.36 atm
