Answer:
10.4 moles
Explanation:
Given parameters:
Number of moles of oxygen = 5.2moles
Number of moles of nitrogen monoxide = ?
Solution:
To solve this problem, we need to work from the known to the unknown specie according to the reaction.
Oxygen gas is known and we can estimate the amount of mole of nitrogen monoxide;
Let us write the balanced reaction equation;
N₂ + O₂ → 2NO
according to this reaction;
1 mole of oxygen gas will produce 2 mole of NO
5.2 moles of oxygen gas will produce (5.2 x 2)moles = 10.4moles
mass = 20.48 g
moles=0.1895
<h3>Further explanation</h3>
In general, the gas equation can be written
<h3>Pv=nRT </h3>
where
P = pressure, atm
V = volume, liter
n = number of moles
R = gas constant = 0.08205 L.atm / mol K
T = temperature, Kelvin
P=0.23 atm
V=20 L
T=23+273=296 K

mass SF₄ (MW=108,07 g/mol) :

The chemical formula of aluminum chloride is AlCl₃ and the chemical formula of aluminum oxide is Al₂O₃.
<h3>Aluminum chloride</h3>
The chemical formula of aluminum chloride is written as;
Al³⁺ + Cl⁻ → AlCl₃
<h3>Aluminum oxide</h3>
The chemical formula of aluminum oxide is written as;
Al³⁺ + O²⁻ → Al₂O₃
Thus, the chemical formula of aluminum chloride is AlCl₃ and the chemical formula of aluminum oxide is Al₂O₃.

The answer is volume, in gasses, volume depends on the matter, but in solids, volume can be measured.
The reaction
→
is best classified as double displacement reaction.
Those reaction in which two compounds react by exchanges of ions to form two new compounds is called double displacement reaction. The easiest way to identify double displacement reactions is to check to see whether the cations exchanged anions with each other or not . Always balanced chemical equation is used to determine.
There are three types of double displacement reaction which is given as,
- Precipitation
- Neutralization
- Gas formation
The real world example of double displacement reaction is combining vinegar and baking soda to create homemade volcano.
