Answer:
This is because Corn is grown on land and has important values to man .These values include as a source of food for man and animals. It is also used as raw materials for the production of certain goods such as flour etc.
It is an energy resource because fermentation of corn gives rise to ethanol fuel which is used as a source of power to run machines and other equipment.

Answer:
O2 - exhibits dispersion forces as its strongest intermolecular force.
Explanation:
Generally speaking, all biatomic homonuclear molecules, such as N2, O2, F2, do NOT have any dipole moment: the distibution of the nuclear clouds is symmetrical. They are non-polar.
For what concerns heteronuclear molecules, it depends on their geometry.
Dispersion force ( Van der Waal)< dipole dipole < hydrogen bond
Intermolecular forces are forces of attraction between molecules/atoms based mainly on the idea of like charges repel and opposite charges attract.
Based on the polarity of the substance, the type of intermolecular forces existing between substance may be different.
Energy cannot be created or destroyed.
I had a test with this not long ago and got it correct.
Answer:
molarity of a solution = 1.192 M
Explanation:
- molarity [=] mol compound / L solution
∴ mass NaCl = 195 g
∴ molar mass NaCl = 58.44 g/mol
⇒ moles NaCl = (195 g)*(mol/58.44 g) = 3.34 mol
∴ Volumen solution = 2.8 L
⇒ Molarity NaCl solution = (3.34 mol)/(2.8 L) = 1.192 M
