explain how both hydrogen and carbon have achieved stability by bonding with each other to form methane
2 answers:
Each element tries to achieve stability by forming a noble gas configuration (2 or 8 valence electrons)
Carbon has 4 valence electrons, achieving stability requires 4 more electrons
Hydrogen has 1 valence electron, achieving stability requires 1 more electron
Carbon and hydrogen bond covalently by sharing their electrons so that they become stable (carbon binds 4 hydrogens) to form CH₄ (methane)
A carbon iota can bond with four other iotas and is just like the four-hole wheel, whereas an oxygen iota, which can bond only to two, is just like the two-hole wheel.

On adding salt.....The boiling temperature increases..... So ∆t= KB * molality =O.52*(58/58)/4 = O.52*1/4 = 0.13 So increase is 100+.13=100.13°c
Wym kingdom? I dont get it
The density does not change because it is still the same liquid as before
C₀=8.10M c₁=5.28M v₀=1.58 L v₁-? n=c₀v₀=c₁v₁ v₁=c₀v₀/c₁ v₁=8.10*1.58/5.28=2.42 L
