3. What are the steps to solving numeric Problems?

4. Solid ex. Gold Liquid ex. Water Gas ex. Oxygen

6. Mass- a measure of the amount of matter the oxygen contains.
Volume- a measure of the space occupied by the object.

8. Heterogeneous mixture- in a mixture composition is not uniform
Heterogeneous mixture- in a mixture composition is not uniform. Homogeneous mixture- in a mixture the composition is in uniform.

9. What is the difference heterogeneous and homogeneous mixtures?

10. Percent error= |error| / accepted value * 100%

11. What is the formula to find the percent error?

12. Number of neutrons= mass number – atomic number

13. What is the formula to determine the number of neutrons in an element?

14. Atomic number is at the bottom of the element and the mass is at the top of the elements symbol.

15. What is the position of the atomic number and the mass when writing isotopes?

16. A group goes vertical on the periodic table and the period is vertical.

17. What is the location of a group and a period on the periodic table?

18. So far we know that it goes up to 7s

19. What is the highest shield that the electron configuration goes to?

20. 1s2 2s2 2p6 3s2 3p3

21. What is the electron configuration for phosphorus?

22. Cation: an ion with a positive charge
Cation: an ion with a positive charge. Anion: An ion with a negative charge.

23. What is the difference between Cation and Anion?

24. Cation and Anions are used to tell when an atom has loss of gained an electron by trying to complete the octet rule.

25. What is the reason for having cation and anions?

26. NaCl is a compound that is composed of a cation and anion.

27. What is an ionic compound?

28. Electron Dot Structure

29. What is the figure showing?

30. Methane

31. What is the VSEPR diagram for methane?

32. Polyatomic ions: composed of more than one atom.

33. What is a polyatomic ion?

34. The name of Cation first then followed by the Anion.
MgO

35. What is the correct way to write a Binary compound?

36. Dichlorine octoxide is the name for Cl2O8.

37. What is the name of Cl2O8 using the prefixes?

38. Hydrochloric acid is the name of chloride
Hydrochloric acid is the name of chloride. The hydro comes from the ide part in chloride.

39. What is the prefix of the acid if the ion ends in ide?

40. Ide ending generally indicates a binary compound.
Ite or ate ending means a polyatomic ion that includes oxygen is in the formula.
Prefixes in a name generally indicate that the compound is molecular.
Roman numeral after the name of a cation shows the ionic charge of the cation.

41. What are the Four ways to writing chemical formulas?

42. Moles= representatoive particles * 1 mole/ 6.20*10^23 rp

43. What is the formula to convert particles into moles?

44. Repres. Particles= moles*6.02*10^23 repr. Particles/ 1 mole

45. What is the formula to covert moles into number of particles?

46. Moles= mass(grams) * 1 mole/ mass(grams)

47. What is the formula to find the mole?

48. Volume of gas= moles of gas* 22.4L/1 mol

49. What is the formula to calculate the volume at STP?

50. % mass of element= Mass of element / mass of compound* 100%

51. What is the formula to find the percent mass of the element?
