What is the formula of hydrogen peroxide
H2O2
What is a neutralization reaction?
(Acid base cancelling each other
What is a catalyst
compound that speeds up reaction
What gas was produced in elephant toothpaste reaction
Oxygen
What are the components of a PPE?
Gloves, Lab coat, Safety goggles
What gas was evolved when you mixed citric acid basking soda and water.
CO2
What dye did we use in our titration reaction
phenolphthalein
because of the lone pairs on oxygen
breakdown of H2O2
What is the purpose of titration?
to find the concentration of acid or base)
What color is phenolphthalein in acid, in base
colorless, pink
what is Ph of concentrated HCl
1-3
Give me the main difference be endothermic and exothermic reaction
endo absorbs heat, exo releases heat
7 is neutral. below 7 acidic, above 7 basic
what was the precipitate formed when we mixed Lead nitrate and potassium iodide ? What was its color?
Why do you think hydrogen peroxide and dish soap did not give us the expected reaction?(In the elephant toothpaste reaction)
Because it lacked the catalyst
no chlorine
What did we add in our jar for luminol experiment
(ammonium carbonate, sodium carbonate, baking soda, copper sulphate +H2O2 and water) (sodium hydroxide luminol)
What is the molecular geometry of CH4
Tetrahedral
What is the formula of carboxylic acid
COOH
