Is glucose a pure substance? Pure Substances: Matter can be divided into two different categories: pure substances and mixtures. If the matter has just one type of element or one type of molecule, it is a pure substance. If matter has more than one atom and/or molecule, then it is a ...
In its open-chain form, the glucose molecule has an open (as opposed to cyclic)unbranched backbone of six carbon atoms, where C-1 is part of an aldehyde group H(C=O)−. Therefore, glucose is also classified as an aldose, or an aldohexose. ...
Is a molecule (carbohydrates,fat, protein,DNA/RNA) larger in size or a molecular complex (dimers, trimers, tetramers)? Answer and Explanation: A molecular complex is made up of multiple molecules. So assuming you are comparison a single type of mo...
In one step, lactose is hydrolyzed (broken down into smaller molecules by using water) to glucose and galactose. In the second step, galactose is isomerized (changed to a molecule with the same chemical formula but a different atom arrangement) to D-tagatose by adding calcium hydroxide. ...
aThe oxygen atom of the water molecule is more electronegative than the hydrogen atom (i.e., it attracts more the electrons). As a result, the side of the molecule with the oxygen atom has a partial negative charge. A molecule with such a charge difference is called a dipole.[translate]...
Using the desired end concentration of 0.25 M from the equation, we know that this equals 0.25 moles per 1L. To determine how many grams of glucose...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question ...
What Is The Difference Between A Permanent And A Temporary Dipole? Permanent dipolesarise due to the difference in the electronegativity (relative attraction towards electrons) between two atoms inside a molecule. Let’s consider hydrogen fluoride as an example. The electronegativity of fluorine is gre...
