How do you describe the structure of water?
A water molecule consists of two hydrogen atoms and one oxygen atom. The three atoms make an angle; the H-O-H angle is approximately 104.5 degrees. The center of each hydrogen atom is approximately 0.0957 nm from the center of the oxygen atom.
What is water molecule structure?
What is structure of h2o?
The water molecule is comprised of two hydrogen (H) atoms and one oxygen atom. The oxygen atom has 8 electrons, and each H has 1 electron. The H atoms bond to the oxygen by sharing a pair of electrons in what is called a covalent bond.
Is h2o bent or tetrahedral?
Water has 4 regions of electron density around the central oxygen atom (2 bonds and 2 lone pairs). These are arranged in a tetrahedral shape. The resulting molecular shape is bent with an H-O-H angle of 104.5°.
Is water acidic or base?
Pure water is neither acidic or basic; it is neutral.
What type of structure is H2O?
Water is a simple molecule consisting of one oxygen atom bonded to two different hydrogen atoms. Because of the higher electronegativity of the oxygen atom, the bonds are polar covalent (polar bonds).
What is structure of H2O?
Why is water’s structure bent?
The reason water has a bent shape is that the two lone pair of electrons are on the same side of the molecule. This repulsion of the lone pairs of electrons on the oxygen atom causes the bond of the hydrogen to the oxygen to be pushed downward (or upward, depending on your point of view).
What is the full name of h2o?
H. 2. O is the chemical formula for water, meaning that each of its molecules contains one oxygen and two hydrogen atoms.
Why is water a neutral?
Water is considered neutral because the concentration of hydrogen and hydroxide ions is the same.
What are the characteristics of a monomer?
Monomer, a molecule of any of a class of compounds, mostly organic, that can react with other molecules to form very large molecules, or polymers. The essential feature of a monomer is polyfunctionality, the capacity to form chemical bonds to at least two other monomer molecules.
Which is an essential feature of a monomer molecule?
Monomer, a molecule of any class of compounds, mostly organic, that can react with other molecules to form very large molecules, or polymers. The essential feature of a monomer is polyfunctionality, the capacity to form chemical bonds to as least two other monomer molecules.
Where does the word monomer come from in chemistry?
The term monomer originates from mono- (one) and -mer (part). Monomers are small molecules that can be joined to form more complex molecules called polymers in a repeated fashion. Monomers form polymers by the formation of chemical bonds or the supramolecular binding through a process called polymerization.
How many monomers are needed to make a polymer?
…which relatively small molecules, called monomers, combine chemically to produce a very large chainlike or network molecule, called a polymer. The monomer molecules may be all alike, or they may represent two, three, or more different compounds. Usually at least 100 monomer molecules must be combined to make a product….
