Answer:
The reaction in this experiment is termed an iodine clock reaction, because it is the molecular iodine (I2) that undergoes the sudden concentration change. When the iodine concentration increases, it reacts with the starch in the solution to form a complex, turning it a deep blue-black color.
Answer:
Sorry I’m not rlly sure but maybe the 2nd or the last
Explanation:
Answer:
Malachite green has highest percentage of copper.
Explanation:
Azurite: 
Molar mass of Azurite = M = 344.67 g/mol
Atomic mass of copper = 63.55 g/mol
Percentage of copper in Azurite :
The percentage of copper in an azurite is 55.31%.
Malachite: 
Molar mass of Malachite = M = 221.12 g/mol
Atomic mass of copper = 63.55 g/mol
Percentage of copper in Malachite:
The percentage of copper in an malachite is 57.48%.
Answer:
The first agrument.
Explanation:
Because only heat can be transfered. Thats why if you put something hot in a refridgerator the heat energy will go off in the fridge and powers the cold energy. Im pretty sure this is right this is what my teachers tought me so i hope they right
Answer:
The answer to your question is pH = 9.08
Explanation:
Data
pH = ?
Concentration = 1.2 x 10⁻⁵ M
Process
1.- Calculate the pOH of the solution
Formula
pOH = -log[OH⁻]
pOH = -log[1.2 x 10⁻⁵]
pOH = 4.92
2.- Calculate the pH
Formula
pH = 14 - pOH
Substitution
pH = 14 - 4.92
Result
pH = 9.08
