A6 Hydrogen peroxide, H2O2, is a covalent compound. Hydrogen peroxide decomposes to form water and oxygen according to the equation:2H2O2(1)→2H2O(1)+O2(g)(a) The decomposition of hydrogen peroxide involves a change from the liquid state to the gaseous state Descnbe the difference in both...
Chemical bonding leads to the formation of the chemical bond between two atoms or molecules or ions to form a chemical compound. Atoms are held together by the chemical bond. Types of chemical bonds are: Ionic bonds Hydrogen bonds Covalent bonds Polar bonds Coordinate bonds...
Answer to: (a) If a substance has a high melting point, is it more likely to have an ionic or covalent bond? (b) Why? By signing up, you'll get...
Is CH4 ionic or covalent? Methane, CH4, is acovalent compoundwith exactly 5 atoms that are linked by covalent bonds. We draw this covalent bonding as a Lewis structure (see diagram). The lines, or sticks, as we say, represent the covalent bonds. There are four bonds from a central carb...
In 2005, Dramsi and coworkers [69] showed that the strongly conserved motif LPXTG corresponds to a pivotal part of the aggregation substance’s molecule and its distinctive sequence is regarded as the site of recognition and cleavage by sortases which bind via a covalent bond to the cell ...
