In anatomy, the second cervical vertebra of the spine is named the axis or epistropheus. By the atlanto-axial joint, it forms the pivot upon which the first cervical vertebra, which carries the head, rotates. The most distinctive characteristic of this bone is the strong odontoid process known as the dens which rises perpendicularly from the upper surface of the body. That peculiar feature gives to the vertebra a rarely used third name: vertebra dentata. In some judicial hangings the odontoid pr
1 An acid-base reaction is type of double displacement reaction that occurs between an acid and a base. 2  The H + ion in the acid reacts with the OH-ion in the base to form water and an ionic salt: 3  HA + BOH â H 2 O + BA. 4  The reaction between hydrobromic acid (HBr) and sodium hydroxide is an example of an acid-base reaction: Direct Combination or Synthesis Reaction. 2  In a synthesis reaction two or more chemical species combine to form a more complex product. 3  A + B â AB. 4  The combination of iron and sulfur to form iron (II) sulfide is an example of a synthesis reaction :
Answers: 4 examples of a chemical reaction would be: -formation of a precipitate-colour change-formation of a gas(bubbles) -temperature increase. Question: and u better have the rite answer. Answers: There are a lot of signs showing a chemical reaction has occurred.Here are four: Formation of a precipitate, change in color, increase or decrease in temperature, bubbles. Question: In a lab, silver nitrate, AgNO3, is dissolved in water until no solid is observed in the container.)The lack of temperature change indicates a chemical reaction didn't occur. 4) A chemical reaction did occur when the solutions were combined. 5) The color change of the solution indicates a chemical reaction occurred. 6) A chemical reaction occurred when silver nitrate was added to water.
