Transcript of "8.1 the secret language of chemical equations"

  1. 1. Formula Review <ul><li>Every formula has two halves, a positive and a negative. </li></ul><ul><ul><li>The positive is always written first. </li></ul></ul><ul><li>Write the formula for Lithium carbonate. </li></ul><ul><ul><li>Li 1+ CO 3 2- </li></ul></ul><ul><ul><li>Li 2 CO 3 </li></ul></ul><ul><li>If you still cannot write formulas you need to come in for help. All of semester two is based on this. It is not going to go away. </li></ul>
  2. 2. Don’t forget the diatomics <ul><li>H, N, O, F, Cl, Br, and I </li></ul><ul><li>when not combined with another element in a compound will always be diatomic. </li></ul><ul><li>H 2 , N 2 , O 2 , F 2 , Cl 2 , Br 2 , I 2 </li></ul>
  3. 3. Now its time for EQUATIONS <ul><li>Sodium metal reacts with water to form aqueous sodium hydroxide and hydrogen gas. </li></ul><ul><li>WHAT? </li></ul><ul><li>Solutions of lead II nitrate and lithium iodide react to form solid lead II iodide and lithium nitrate solution. </li></ul><ul><li>AHHHHHH! MAKE IT STOP! </li></ul>
  4. 4. You need to learn… <ul><li>The secret language of chemical equations. </li></ul>
  5. 5. Words that mean + <ul><li>These words will be between formulas. </li></ul><ul><ul><li>React </li></ul></ul><ul><ul><li>And </li></ul></ul><ul><ul><li>In the presence of </li></ul></ul><ul><ul><li>Combine </li></ul></ul><ul><ul><li>With </li></ul></ul><ul><ul><li>Dissolved in </li></ul></ul>
  6. 6. Words that mean <ul><li>These words divide the equation into two halves, the reactants and the products. </li></ul><ul><ul><li>Form or to form </li></ul></ul><ul><ul><li>To produce </li></ul></ul><ul><ul><li>Yield or yields </li></ul></ul>
  7. 7. States of matter <ul><li>States of matter are also included in a chemical equation. </li></ul><ul><ul><li>(s) = solid, metallic, crystal </li></ul></ul><ul><ul><li>(l) = liquid </li></ul></ul><ul><ul><li>(g) = gas, vapor </li></ul></ul><ul><ul><li>(aq) = aqueous, solution </li></ul></ul>
  8. 8. Sample equation… <ul><li>H 2(g) + O 2(g) H 2 O (l) </li></ul><ul><li>Look at the equation in parts: </li></ul><ul><ul><li>Hydrogen gas </li></ul></ul><ul><ul><li>reacts with </li></ul></ul><ul><ul><li>oxygen gas </li></ul></ul><ul><ul><li>to form </li></ul></ul><ul><ul><li>liquid water </li></ul></ul>
  9. 9. <ul><li>Lets look at those equations again… </li></ul>
  10. 10. <ul><li>Sodium metal reacts with liquid water to form aqueous sodium hydroxide and hydrogen gas. </li></ul>
  11. 11. <ul><li>Solutions of lead II nitrate and lithium iodide react to form solid lead II iodide and lithium nitrate solution. </li></ul>
