Not quite sure what you mean by matter ? Yes air is matter and yes it does matter ! Air is various gasses that support life and other things ! We use air for so many things, it's very important c:
Answer:
CH3NH2 : Hydrogen bonding and London dispersion forces
F2 : Hydrogen bonding, dipole-dipole and London dispersion forces
NOF : Dipole-dipole forces
C2H6 : London dispersion forces
H2O : Hydrogen bonding and London dispersion forces
Increasing order of boiling point:
F2
C2H6
NOF
CH3NH2
H20
Explanation:
London dispersion forces exist in all substances
CH3NH2 : The hydrogen bonding in the amine group and the assymetry of the molecule makes the hydrogen bonding and dipole-dipole bonds from the methyl group.
F2 : The bond is non polar because its a homonuclear bond
NOF : Dipole-dipole forces due to difference in elecronegativity between all the atoms involved and assymetry
C2H6 : London dispersion forces because all dipole-dipole forces are cancelled out due to the symmetry of the molecule
H2O : Hydrogen bonding between hydrogen and oxygen and the assymetry of the molecule
Order of boiling points: London dispersion forces, followed by dipole-dipole forces and hydrogen bonding is the strongest
When carbon is burned in air carbon iv oxide gas is formed.
C (s) + O2 (g) = CO2(g) ΔH = - 393.5 kj/mol
The enthalpy change of the reaction is -393.5 j/mol which means that when one mole of carbon is completely burnt in air then 393.5 j of energy is evolved.
Thus, 1 mole = -393.5 j , then for 480 kj
= 480 × 1/393.5
= 1.2198 moles
1 mole of carbon iv oxide is equal to 44 g
thus, 1.2198 moles will be 1.2198 × 44 = 53.6712 g of CO2
A white rabbit would therefore have (ff)
If a trait is recessive, then it can only be expressed if both alleles (individual letters) are recessive (lowercase).
Biodiversity helps an economy grow and develop over time because such as the circle of life we need other things in order to evolve such as trees so we can be able to breathe and plants so the herbivores can eat so we can eat them because we are all part of a cycle and in order to keep the cycle going we need biodiversity to keep the food chain going and our economy well and lifted
