An alkoxide is an organic functional group formed when a hydrogen atom is removed from a hydroxyl group of alcohol when reacted with a metal. It is the conjugate base of alcoho.
Answer:
480 g of oxygen.
Explanation:
C3H8 + 5O2 ---> 3CO2 + 4H2O
Using the molar masses:
3*12 + 6*16 g of CO2 were formed from 10*16 g O2
132g g CO2 from 160 g O2
1g CO2 from (160/132) g O2
396 g from (160/132) * 396
= 480 g of oxygen.
H₂SO₄ represents Sulphuric acid or SO₄²⁻ ion when in aqueous as well as H⁺ and a little amount of HSO₄⁻ all of these ions can form in aqueous on dissolving H₂SO₄
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.
