Identify 3 of each Acid and Base in the general Home |
Acetic Acid, Lactic Acid, Ascorbic Acid, Sodium hypochlorite, Sodium hydroxide, Sodium bicarbonate. |
|
|
Name the Gastric Acid found the Stomach and has a pH of 1 |
Hydrochloric Acid |
|
|
True or False: All nitrates are soluble except CaNO3 |
False |
|
|
True or False: When Litmus paper reacts to an acid it turns red. |
True |
|
|
We define pKai = - log(Kai), and the pKai value is also the pH value at which the colour of the indicator is most sensitive to pH changes. With this in mind, is a pH of 2.5 still an acid? |
Yes |
|
|
Which of the following is not neutralised? A) Sulfuric Acid + Potassium Hydroxide B) Nitric Acid and carbon hydroxide C) Copper Sulfate reacting to Calcium carbonate |
C) Copper Sulfate reacting to Calcium carbonate |
|
|
In the formula equation 4Cu+ 02 = 2Cu20 what is rusting and what colour does it show? |
Copper is rusting, turning green. |
|
|
Write the Formula: Aluminium reacts to oxygen to form Aluminium oxide. |
Al + O2 = Al2O3 |
|
|
Write the word equation: 4(Fe)+ 6 H2O+ 3 O2 = 4Fe(0H)3 |
Iron plus oxygen to form rust |
|
|
Copper carbonate + hydrochloric acid = Copper chloride, Zinc Carbonate + Nitric Acid = Zinc Nitrate and Iron Carbonate + Sulphuric Acid = Iron Sulfide is a chemical reaction involving what? |
Acid and a Carbonate |
|
|
Define what an Exothermic reaction is and how it is different to an endothermic reaction. |
Exothermic reactions release heat.Endothermic reactions absorb heat. |
|
|
Kidney stones form when your urine contains more crystal-forming substances — such as calcium, oxalate and uric acid — than the fluid in your urine can dilute. At the same time, your urine may lack substances that prevent crystals from sticking together, creating an ideal environment for kidney stones to form. With this in mind, is a Kidney stone a catalyst, Precipitant or a soluble |
Precipitant |
|
|
AB --> A+B. Identify what this example is can define it. |
Decomposition, the breaking down of particles to smaller particles. |
|
|
Describe the effects of temperature, surface area, concentration and catalysts on the rate of some common chemical reactions. |
Surface Area - Increase surface area = increase collision time = increase reaction rate. Concentration - Higher the concentration = faster the reaction Temperature Hotter the temperature = faster the reaction rate Presence/absence of a catalyst Speeds up or slows reaction. |
|
|
Discuss the social and environmental effects of Chemical reactions. This may be involved in the home, nature or industry |
Read with group and discuss if its good |
|
|
How does emerging scientific technology significantly affect peoples lives? |
Read with group and discuss if its good |
|
|
What does I.A.C stand for? |
Identify, Assess, Control |
|
|
A student doing an experiment with 2.0m of Hydrochloric Acid and a universal indicator without the supervision of a certified teacher and scientist. He is wearing is normal school uniform as he should and is extremely careful. What is wrong with this situation and how would you correct it? |
No glasses, eye protection No gloves, hand protection No teacher/scientist. |
|
|
A cheetah accelerates from rest to 90km/hr. What was its acceleration in m/s/s? |
5m/s/s |
|
|
A rocket has an average acceleration of 15m/s/s. How fast would it be travelling if, after lift off it accelerated at the rate for 100s |
1500 m/s |
|
|
In a practical experiment, what is the purpose of a discussion? |
Why something happened, identify problems and state what happens. |
