(4) A tread depth of less than 2/32 of an inch measured in any two major tread grooves at three locations equally spaced around the circumference of the tire, or for those tires with tread wear indicators, a tire shall be considered unsafe if it is worn to the point that the tread wear indicators contact the road in any two major tread grooves at ...
The strength of chemical bonds varies considerably; there are strong bonds such as covalent or ionic bonds and weak bonds such as Dipole-dipole interaction, the London dispersion force and hydrogen bonding. strong chemical bond is formed from the transfer or sharing of electrons between atomic centers and relies on the electrostatic attraction between the protons in nuclei and the electrons in the orbitals. The types of strong bond differ due to the difference in electronegativity of the constituent elements.
Strong acids and strong bases are strong electrolytes [e.g., HCl(aq), H 2 SO 4 (aq), HClO 4 (aq);NaOH(aq)]. There are virtually no molecules of a strong acid or base in solution, only ions.Know the strong acids and bases on the accompanying hand-out Strong and Weak Acidsand Bases. Assume that any other acid or base you encounter in this course is weak, unlesstold to the contrary. [Note: Mg(OH) 2, an insoluble compound, is a strong base because it is anionic compound and therefore a strong electrolyte.].
