15. Ventilation…16. Closed in shoes…17. Soap spots…Sheldon video…https://www.youtube.com/watch?v=9Wmn-U01b_Q==================================Lab safety high schoolershttps://www.youtube.com/watch?v=NjJz85bQqdM===================================Zombie college lab safety – watch only if you like zombies…what are the 5 rules of zombie lab safety?1. safe clothing2. personal protective equipment3. add acid or base to solvent not other way4. safety equipment5. lab behavior

https://www.youtube.com/watch?v=V-fNpaOX0-g = Flinn lab safety challengech 21 = RQ 1-10Possible Misconceptions to CorrectNot so! It would be lethal to ingest an acid or a base.Not so! All salt is made of sodium chloride.Not so! pH’s cannot be less than zero.Not so! Atmospheric carbon dioxide is necessarily bad news.Not so! A half-reaction can occur on its own.Not so! Silver tarnish can only be cleaned by polishing.Not so! Batteries run out because they lose charge.Not so! Playing the car radio has no effect on fuel efficiency.

REVIEW QUESTIONS

1. When an acid is dissolved in water, what ion does the water form?Dissolving an acid in water causes the formation of a hydronium ion.

2. When a chemical loses a hydrogen ion, is it behaving as an acid or a base?A chemical that loses a hydrogen ion is behaving as an acid.

3. Why does a solution of a strong acid conduct electricity better than a solution of a weak acid having the same concentration?A solution of a strong acid has more ions in solution and can conduct electricity better than a weak acid.

4. When can a solution of a weak base be more corrosive than a solution of a strong base?A concentrated solution of a weak base could have more corrosive power than the dilute solution of a strong base.

5. Is water a strong acid or a weak acid?Water is a weak acid.

6. What is true about the relative concentrations of hydronium and hydroxide ions in an acidic solution? How about a neutral solution? A basic solution?If the hydronium ion concentration of a solution is higher than the hydroxide ion then the solution is acidic. If the opposite is true then the solution is basic.

7. What does the pH of a solution indicate?The pH of a solution indicates the acidity of the solution as judged by the concentration of hydronium ions.

8. What is the product of the reaction between carbon dioxide and water?The product of the reaction between CO2 and H2O is carbonic acid, H2CO3.

9. How do humans generate the air pollutant sulfur dioxide?The burning of fossil fuels contributes to SO2 in the air.

10. Why aren’t atmospheric levels of carbon dioxide rising as rapidly as might be expected based on the increased output of carbon dioxide resulting from human activities?

The ocean absorbs the CO2 where it is neutralized and is not re-released.

Grade on glog now. Not in a minute. Now. 10 answers so = -10 each… -5 if done but wrong…if you actually looked it up in your book.

11. Which elements have the greatest tendency to behave as oxidizing agents?The elements in the upper right of the periodic table (except for noble gases) have the greatest tendency to behave as oxidizing agents.

12. What is the difference between an oxidizing agent and a reducing agent?An oxidizing agent causes another reactant to be oxidized (lose an electron), and a reducing agent causes another reactant to be reduced (gain an electron).

13. What is electrochemistry?Electrochemistry is the study of electrical energy and chemical changes.

14. What is the prime difference between a battery and a fuel cell?

Fuel cells are very similar to batteries. Batteries, however, run down, while fuel cells can keep going indefinitely so long as fuel is supplied.

15. What is electrolysis, and how does it differ from what goes on inside a battery?Electrolysis uses electrical energy to produce a chemical change whereas a battery uses a chemical change to produce electrical energy.

16. What do the oxidation of zinc and the oxidation of aluminum have in common?After oxidation, zinc and aluminum both form water-insoluble oxidized coats that prevent further oxidation.

17. What are some differences between corrosion and combustion?Corrosion is the deterioration of a metal by oxidation. Combustion is a redox reaction between a nonmetal and oxygen.

18. What happens to the polarity of oxygen atoms as they transform from molecular oxygen, O2, into water molecules, H2O?The oxygen atoms become more negatively charged, which is to say they are gaining electron.

19. What do we do to food molecules to obtain energy from them?We oxidize food molecules with the oxygen we obtain from the air we breathe.

20. What gas, when provided in the in right concentration, has been shown to induce a state of suspended animation in mice?Hydrogen sulfide, H2S, which is the same smelly stuff of rotten eggs!

PreCalculus

Glogs due Monday.

Remember – all odds must be done then checked then corrected if wrong.HW WAS: notes on video/web math 7.1 vocab Desmos.comhttps://www.desmos.com/calculator Make sure on test day you have a computer… test day is Monday Wednesday 3/9/16. Off Monday and Tuesday Math test on Wednesday…computer!!!graph!

Hw 3/3/16 = do 5 and 6 aboveTake some kind of notes from each …Khan1,2,3,4 videos; Wolfram1,2,3,4,5,6 pages

MONDAY = TEST

Today = 3/9/161. test trig functions 2. hw = read 8.1, 8.2, 8.3 and do vocab for those lessons…Vocab = title of each lesson and title of each example – do in spiral or on notecards if you prefer – do term + definition + example or diagram for each…in a word doc is fine…THIS STUFF ABOVE WILL BE ON THE TEST.P.528 1-12 = = DO THE ODDS FIRST THEN CHECK…THEN CORRECT … THEN DO EVENS.

OTHER 12 th grade HW IS LISTED BELOW: LIT = ROCKET BOYS…vocab worksheet

US HISTORY = finish 22 a b e notes

RELIGION = pray & rice box & project/essay on your cathedrals due 3/10

ECON = finish class notes

Spanish – research your next location … Murcia
