The Balanced Chemical Equation is as follow;
4 KO₂ + 2 CO₂ → 2 K₂CO₃ + 3 O₂
First find out the Limiting Reagent,
According to equation,
284 g (4 moles) KO₂ reacted with = 44.8 L (2 moles) of CO₂
So,
27.9 g of KO₂ will react with = X L of CO₂
Solving for X,
X = (44.8 L × 27.9 g) ÷ 284 g
X = 4.40 L of CO₂
Hence, to consume 27.9 g of KO₂ only 4.40 L CO₂ is required, while, we are provided with 29 L of CO₂, it means CO₂ is in excess and KO₂ is is limited amount, Therefore, KO₂ will control the yield of K₂CO₃. So,
According to eq.
284 g (4 moles) KO₂ formed = 138.2 g of K₂CO₃
So,
27.9 g of KO₂ will form = X g of K₂CO₃
Solving for X,
X = (138.2 g × 27.9 g) ÷ 284 g
X = 13.57 g of K₂CO₃
So, 13.57 g of K₂CO₃ formed is the theoretical yield.
%age Yield = 13.57 / 21.8 × 100
%age Yield = 62.24 %
Answer:
Synthesis
Explanation:
Reaction Given:
NH₃+ HCI ------> NH₄Cl
Type of reaction = ?
Solution:
Look at the reactants and products of the reaction to know the type of reaction
NH₃+ HCI ------> NH₄Cl
In this reaction two reactant combine and give 1 products.
Reactant of the reaction
NH₃ = Ammonia
HCl = Hydrochloric acid
Product of the reaction
NH₄Cl = Ammonium chloride
So,
That ammonia (NH₃) react with Hydrochloric acid (HCl) and produces salt.
in this reaction NH₃ is a week base and take a proton from HCl and form ammonium ion and Cl ion. these two ions in combine form gives a salt called ammonium chloride.
Type of Reaction:
This is type of synthesis reaction, in which NH₃ and HCl combine and form a new compound that is ammonium chloride salt (NH₄Cl). As the synthesis reaction is that reaction in which two are more compounds or molecules combine and form a new compound.
I believe the answer is B, or option 2. It makes the most sense, and is a fact.
Two atoms of nitrogen and four atoms of oxygen because the compound has two molucules of it which is multiplied by its sub to bring the result
