  1. Technicolor atoms Homework

  2. Q1 • How did the flame test provide evidence that specific atoms are present in compounds

  3. Q2 • Explain what is responsible for the colors during the flame test

  4. Q3 • Predict the color of the flame for the compound sodium hydroxide, (NaOH) • Explain your reasoning

  5. Q4 • Imagine you were in charge of creating red and purple fireworks display. Name tow combinations of compounds you could use.

  6. Q5 • What evidence do you have from the flame tests that copper is responsible for producing a flame with a blue-green color/

  7. q6 • Does nitrate produce a colored flame? Explain

  8. Q7 • What flame colors would be produced by these compounds • Na2Co3 • Ba(OH)2 • KOH • K2CO3 • BaO

  9. Q8 • Would it matter whether you did a flame test with sodium chloride, NaCl, in solid form or as an aqueous solution? Explain?

  10. Q9 • If 2 chemical samples both produce an orange flame upon testing, which statement is true? • The 2 samples contain identical compounds • The samples both contain Cl atoms • The samples both contain Ca atoms • The samples both contain K atoms • The samples both contain different compounds

  11. Q10 • Why doesn’t the color indicate the movement of protons or neutrons?

  12. Q11 • Compare the energy released from the breaking apart of the nucleus to that of moving an electron.
