The last answer: <span>P waves move straight through all medium and S waves move only through solids in a curvy motion.</span>
Answer:
anode is negative. cathode is positive.
Displacement reaction
Because Al goes to SO4 and
Cu goes from SO4 to Cu
This happens because Al is more reactive (higher up in the reactivity series) than Cu
40 grams ÷ 40.08 grams/moles = 1 mole
A solution's pH will be a number between 0 and 14. A solution with a pH of 7 is classified as neutral. If the pH is lower than 7, the solution is acidic. When pH is higher than 7, the solution is basic. These numbers describe the concentration of hydrogen ions in the solution and increase on a negative logarithmic scale. For example, If Solution A has a pH of 3 and Solution B has a pH of 1, then Solution B has 100 times as many hydrogen ions than A and is therefore 100 times more acidic.
