Answer:
(70 x 2 + 16 x 3) x 29/70 x 2 = 38,9428571 g.
Explanation:
test tube
Explanation:
you state it is small and a test tube is the smallest container out of the answers you listed
The theoretical yield of Ca(OH)₂ : 42.032 g
<h3>Further explanation</h3>
Given
31.8 g of CaO
Required
The theoretical yield of Ca(OH)₂
Solution
Reaction
CaO + H₂O⇒Ca(OH)₂
mol CaO (MW=56 g/mol) :
= mass : MW
= 31.8 g : 56 g/mol
= 0.568
From equation, mol Ca(OH)₂ = mol CaO = 0.568
Mass Ca(OH)₂ (MW=74 g/mol) :
= 0.568 x 74
= 42.032 g
1. Resonance structures are a better description of a Lewis dot structure .
2. Best resonance structure is the one with the least formal charge.
<u>EXPLAINATION OF RASONANCE STRUCTURE OF CARBON DIOXIDE</u>
1.Carbon dioxide has three resonance structures .
2. The CO2 molecule has a total of 16 valence electrons ,
1C = 4 electrons
2O= 12 electrons
<u>three resonance structures for CO2</u>
1. The atoms in all three resonance structures have full octets;
structure 1 will be more stable because it has no separation of charge.
2. Structures 2 and 3 show charge separation caused by the presence of formal charges on both oxygen atoms.
