Hussam Aldurayhim Dr. Khalique Ahmed Fun Filled Hands On Science 17 January 2013 Demonstrations in Chemistry Class Chemistry is a class that a lot of college student are afraid of‚ and when I think of chemistry‚ complex equations that don’t benefit come to my mind. The reason is that all I got out of chemistry is those unbeneficial equations‚ for me at least. Also‚ I learned that H2O is water. With all those negative statements‚ I still believe that chemistry is a very important subject to understand

the solutions you studied in Module 1 form two classes or groups of materials that are related to each other and are important in daily life. They have common properties that can easily be identified. What do you think are common properties among vinegar‚ calamansi juice‚ and soft drinks? What are common among liquid sosa (drain cleaners)‚ soaps‚ and detergents? Which among these are called acids? Which are classified as bases? In this module‚ you will investigate the properties of acids and bases

Mylana Gerard December 20‚ 2012 10D Introduction: The cell membrane is a protection from anything outside the cell and anything inside of the cell. The purpose of the cell membrane is to selectively choose what comes in the cell. It’s permeable and able to regulate what enters and exits the cell‚ which is facilitating the transport of materials needed for survival. Cell membranes aren’t in just one specific kind of cell because it’s in every cell. The cell membrane is supposed

Take it off to see if the drain is now okay; if the clog is still there‚ repeat the steps until it’s dislodged. Achieve victory with vinegar (and baking soda) You probably already know that vinegar is good for cleaning mirrors and refrigerator shelves. Its talents don’t stop there‚ though‚ since it can also remove clogs when paired with baking soda. If you’re ready to start‚ here are some of the steps you must take:

most to the conductivity due to the high transport numbers for protons in water). Vinegar (acetic acid) when an acid is in aqueous solution (dissolved in water) there are many loose hydrogen ions (and therefore lots of loose anions as well). Ionic solutions are good conductors of electricity. the stronger the acid‚ the more hydrogen ions in solution (and more anions)‚ the better the conductor. weak acids like vinegar (acetic acid) conduct much less well because there are much fewer ions in

will move out of the egg causing it to shrivel and the egg in the water solution will be hypotonic causing the egg to swell. Materials and Methods The materials needed for this experiment are 2 fresh non boiled eggs‚ 2 coffee mugs‚ Aluminum foil‚ vinegar‚ water‚ corn syrup‚ hand towel‚ scale‚ string‚ scissors and a ruler.

shells. The shell that was going into the vinegar was labeled “E” (which stands for experimental) and the shell that was going to be put in the salt water was labeled “C” (which stands for control since it is the control of our experiment). Before we put them into the water/vinegar‚ we recorded some quantitative and qualitative observations such as the mass and color and shape of the shells. Then we took the two beakers and poured the 150mL of salt water or vinegar into them and labeled them according

To titrate an acetic acid solution (vinegar) with standardized 0.5M sodium hydroxide. 4. To utilize the titration results to calculate the molarity of the hydrochloric acid and the molarity and percent composition of the vinegar.

The results after being in the Dr. Pepper is the pork chop 16.1 grams‚ chicken breast 13.5 grams‚ beef roast 13.1 grams. The results of the distilled water were and vinegar were.The hypothesis which stated that the mass of the pork chop will increase was supported because the results was 16.1 grams and the chicken breast and beef roast results came out to the thirteens. If the experiment was repeated the type of meat
