A sugar molecule is quite a bit larger than salt molecules. Why? Sugar is an organic molecule made of Hydrogen, Carbon, Oxgen the ratios and exact structure vary with the type… of sugar. Salt is a rock, it's chemical formula is NaCl (common table salt, or sodium chloride), whereas sugar, sucrose being the common table sugar has a chemical formula of C12H22O11.
Does sugar dissolve in water because the positive ends of the sugar molecules are pulled off the solute surface by the negative ends of the water molecules?
A combination of 2 hydrogen atoms and 1 oxygen atom.
Yes salt molecules are bigger than water molecules.
Here's how it goes: the sugar cube is made up of a bunch of sugar crystals, each made of a specific number of sugar molecules (I think six, but I'm not sure). It is a polar mo…lecule, meaning that there is a slight positive charge at one place (likely a hydrogen) and a slight negative charge at another (likely an oxygen). Since water is also polar, it tends to pull the sucrose crystals apart into individual sugar molecules and aligns the charges of its own molecules with those of the newly introduced sugar molecules, positive charges attracting to negative charges. This means that the sugar gets "trapped" molecule by molecule between molecules of water.
Yes. Table sugar consists of an organic molecule known as sucrose. Sucrose contains many carbon and hydrogen atoms. Because of this, a molecule of sugar is much large than a m…olecule of water, which consists only of an oxygen atom bonded to two hydrogen atoms.
They are both molecules bonded by covalent bonds.
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.
The white stuff we know as sugar is sucrose, a molecule composed of 12 atoms of carbon, 22 atoms of hydrogen, and 11 atoms of oxygen (C12H22O11). Like all compounds made from …these three elements, sugar is a carbohydrate. It's found naturally in most plants, but especially in sugarcane and sugar beets---hence their names. Sucrose is actually two simpler sugars stuck together: fructose and glucose. In recipes, a little bit of acid (for example, some lemon juice or cream of tartar) will cause sucrose to break down into these two components. If you look closely at dry sugar, you'll notice it comes in little cube like shapes. These are sugar crystals, orderly arrangements of sucrose molecules.
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.
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.
Perhaps you mean: Does sugar have more atoms than water? In a certain fixed mass of sugar/water, there will be more molecules of water than of sugar since the molecular m…ass of sugar is higher than that of water. We follow the rule of Mass = Number of moles of a substance * Molecular mass of the substance. We rearrange this to form Number of moles = Mass / Molecular mass Therefore, since the molecular mass of sugar is higher, the number of moles of sugar in a fixed mass of sugar is lower. The number of moles of sugar is directly proportional to the number of molecules of sugar, since we follow Avogadro's Law: 1 mole = 6 * 10^23 molecules (constant value) However, if you meant to ask if sugar had more atoms than water, the answer is yes, it does. Sugar (presumably glucose) has the chemical formula of C6H12O6 and thus has 24 C, H and O atoms altogether. Water, with the formula H2O, has 3 atoms of H and O altogether. I hope this was helpful! :)
Yes it does. Sugar has atoms of Carbon, Hydrogen and Oxygen in its molecules. The commonest for of sugar (Glucose) has the chemical formula C6H12O6 - See related… link fro more information.
Water molecule. A carbon atom has van der waals radius of 340 pm, but a water molecule on the same measure is about 275 pm.
Yes. Water and sugar both contain hydroxyl groups, which consist of an oxygen atom bonded to a hydrogen atom. Because of this shared particle level property, water and sug…ar molecules will attract each other, which is why sugar is so easily water-soluble.
