Answer:
Bleach and seawater are identified wrong.
Explanation:
Acids have an pH that is lower than 7 and bases have a pH of higher than 7 and (pH 7 is neutral)
We can observe from the table that bleach has a pH of 13 which is higher than 7 and shows basic characteristics
As for seawater the table shows it has a pH of 8 which is also a base. Therefore the answer is 3rd option "Bleach and seawater should be identified as bases".
Answer:
The gain in mass by the negative electrode is the same as the loss in mass by the positive electrode. So the copper deposited on the negative electrode must be the same copper ions that are lost from the positive electrode.
B is the.answer for this problem
4 grams , mass cannot be created or destroyed. it has to be the same on both sides of the equation
Explanation:
Planck's law describes the spectral density of electromagnetic radiation produced by a black body in thermal equilibrium at a given temperature, where there is no net flow of matter or energy between the body and its environment.
Hope this helps : )
