Answer:
A Scientific hypothesis must be testable, for a hypothesis to be testable means that it is possible to make observations that agree or disagree with it. This statement may or may not be true, but it is not a scientific hypothesis. That's because it can't be tested.
Explanation:
The substance would be:Methanol (ch40)
Answer is: charges are balanced during redox.
1) False. Electrons are produced on zinc rod (Zn → Zn²⁺ + 2e⁻)
2) False. Electrons flow from anode (negative electrode) to cathode (positive electrode).
3) False.Oxidation occurs at the zinc electrolyte (Zn → Zn²⁺).
Answer:
Explanation:
<u>Given the following data;</u>
Initial volume = 400 mL
Final volume = 2000 mL
Initial pressure = 3 atm
To find the final pressure P2, we would use Boyles' law.
Boyles states that when the temperature of an ideal gas is kept constant, the pressure of the gas is inversely proportional to the volume occupied by the gas.
Mathematically, Boyles law is given by;
Substituting into the equation, we have;
