Thanks for the feedback!
A combination of 2 hydrogen atoms and 1 oxygen atom.
Glucose molecules are bigger than water molecules.
The sugar molecule is larger.
One water molecule may surround by four other water molecules tetrahedrally as in case of ice.
Different elements have different electro-negativities. Electro-negativity is the ability of an atom to withdraw 'electron density' towards itself, i.e. it makes electrons com…e closer to it. Fluorine is the most electronegative of the elements. Oxygen is more electronegative than hydrogen and so in water (H2O) the oxygen 'pulls' the electrons closer to itself and become slightly negative, and the hydrogen's slightly positive, this is called a permanent dipole. Due to this effect water has many properties that make it unusual and important to living things.
Thinking logically here... USING MY BRAIN!!! If there is 1 molecule of water for every 1 molecule of water, then the proportion of water molecules in water will be the same. 1…:1.
Air molecules is a little vague, the air that we breath is a mixture of mainly nitrogen (72% or so) oxygen and carbon dioxide. A water molecule is H20, two hy…drogen polar covalently bonded to one Oxygen. Besides for the two bonds to H the oxygen also has 2 lone pairs of electrons. To spread the charge the molecule has a bent shape. Due to the difference in electronegativity between H and O and the shape of the molecule water is polar. This allows water to hydrogen bond which connect s the H from one molecule to the O of another molecule, holding water together as a liquid. When you boil water these intermolecular forces are overcome and each individual molecule separates from each other, creating water vapor ( which is water in the gas phase). However, each individual water molecule remains the same.
Yes water is a polar molecule
The size of a molecule depends on the size of the atom. The smallest a molecule can be is two atoms.
Water is a type of polar molecule. It is polar because it has two hydrogen atoms bonded uniquely to one atom of oxygen causing different charges in different areas.
A starch molecules is technically any polymer of sugar. These polysaccharides may be composed of as few as three sugar molecules and can stretch into the thousands and mil…lions of sugar subunits in nature.
no difference same exact molecule
Molecules did not exist at the time of the Big Bang and not even in the immediate time after. To make molecules one needs atoms but it took about 370.000 years after the Big B…ang for the temperature had dropped enough for atoms to be stable.
Water molecules dont necessarily dissolve in water. Because water is a polar molecule, it has a slightly positive and slightly negative side to each molecule. The positive… and negative sides of each water molecule are attracted to other positive and negative sides of other water molecules.
