Answer:
0.027mol
Explanation:
9M NaOH tells us that there is 9 mol of NaOH per L of NaOH
converting 3mL to L = 0.003L
0.003L * 9 mol/L = 0.027mol
Protons and Neutrons is what determines the atomic mass. I cannot further explain this answer, however, I hope I helped!
Answer:
C. The reaction rate at known reaction concentrations
Explanation:
The rate of a reaction is the measure of the speed of a chemical reaction. To find the rate constant of a reaction, the concentration of the reactants must be known.
- Reaction rate is directly proportional to the concentration of the reactants.
- The quantitative relationship between the rate of a reaction and the concentrations of reactants is expressed as the rate law.
- From this we can deduce the rate constant.
Answer:
The answer is option C.
Explanation:
A covalent bonded molecule when not dissolved in an aqueous solution does not contain any ions hence does not conduct electricity making it an insulator.
Hope this helps you.
Answer:
iron is less reactive
Explanation:
therefore it will be extracted using carbon as it forms less stable oxides so little energy is needed to extract the metal.
