The bond in O2 is a double bond, meaning two pairs of electrons are shared between two atoms. Double bonds are shorter than single bonds because of the second electron pairs presence over the single bond. This pulls the atoms closer together.
A nitrogen molecule (N2) is smaller than a propane molecule (C3H8). The size of a molecule is determined by its molecular weight and structure. Nitrogen is a diatomic molecule composed of two nitrogen atoms, while propane is a larger molecule composed of three carbon and eight hydrogen atoms.
Neil deGrasse Tyson compares the number of atoms in one molecule of DNA to the number of stars in the Milky Way galaxy.
Hydrogen bonding is a weak electrostatic attraction between a covalently bonded H on one atom with an electronegative atom in another molecule. In water this is a bond between the H of one H2O molecule and the O of another. The effects are remarkable. Boiling point and melting point are much higher than you'd expect (compare H2S) the density of ice is lower than that of liquid water.
Glycerol C3H8O3 has three Carbon, eight Hydrogen and three Oxygen.
NO is polar. If you compare the electronegativities (how strongly the element pulls on electrons) N 3.04 O 3.44 ( bigger therefore pulls electrons harder) The electrons will be drawn to the oxygen causing it to be slightly negative, and the N to be slightly positive.
Explain the similarities between two or more objects.
Calculate volume of molecule, calculate mass of molecule, compare to bulk density. Lower bulk density indicates empty space.
Compare: Explain how two or more things are the same. Contrast : Explain how two or more things are different.
hhhghgh
To determine which molecule is the most polar, compare the electronegativity difference between the atoms in each molecule. The greater the electronegativity difference, the more polar the molecule. Additionally, look at the molecular geometry and symmetry of the molecule, as asymmetrical molecules tend to be more polar.
ask me.
explain what you'll compare and contrast in the essay and why. (apex)-jfattie:))
The grammatic difference between compare to and compare with is mainly that when a person compares something to something else it is different then comparing with.
Yes
Convert the mixed number to a decimal.
so scientist can compare result
Convert them to decimals and order them least to greatest.
