ANSWER: Milk
Explanation: Take this chart from 1-6 are acids from 8-14 those are bases
Now bases are like cleaning products and stuff
While acids are like lemons and other stuff
If you look at milk level which is 6.5 It is an acid but its A lot closer to neutral Than Other acids
Zinc is no longer the positive electrode because copper has a more positive (higher) value than zinc (anode). The anode value is reduced by the potential of the other electrode.
<h3>In a galvanic cell, is the anode positive or negative?</h3>
In a galvanic (voltaic) cell, the cathode is regarded as positive and the anode as negative. This seems reasonable given that the cathode is where electrons flow from the anode, which is where they originate.
<h3>What is a galvanic cell?</h3>
An electrochemical cell called a galvanic cell or voltaic cell, respectively named after the scientists Luigi Galvani and Alessandro Volta produces an electric current by spontaneous oxidation-reduction reactions. A typical device typically consists of two distinct metals that are submerged in separate beakers that each contains their own metal ions in solution and are either connected by a salt bridge or divided by a porous membrane.

The kinetic energy and the physical state of water depend strongly on the temperature;
- Firstly, The kinetic energy of water on a hot stove is higher than that on the counter in the freezer; that the kinetic energy is directly proportional to the temperature according to the relation:
; where R is the universal gas constant, T is the temperature and NA is Avogadro number.
As the temperature increases, the speed of colliding molecules increases and the kinetic energy increases.
- Secondly, The physical state of water depends on the temperature; water has three states (gas, liquid and solid) depends on the temperature.
- If a glass of water is putt on the counter in the freezer, it will be converted to the solid state (ice).
- And, as if it is putt on a hot stove, it will be vapor (gaseous state).
I think the correct answer from the choices listed above is option A. In the modern periodic table, elements are arranged according to increasing <span>atomic number. The atomic number represents the number of protons present for a specific atom.</span>
A change in the force of gravity on an object will affect its weight.
