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.

This is a dilution that requires a certain volume from the stock solution to be diluted with distilled water to make a solution of HBr with a lesser concentration than the stock solution
Following dilution formula can be used
c1v1 = c2v2
Where c1 is concentration and v1 is the volume of the stock solution
c2 is concentration and v2 is volume of the diluted solution to be prepared
Substituting these values
10.0 M x v1 = 3.0 x 450.0 mL
v1 = 135.0 mL
A volume of 135.0 mL from HBr stock solution needs to be taken and diluted with distilled water upto 450.0 mL. The resulting solution will have a concentration of 3.0 M
Seems to me it's graph A, based on the trends.
Answer:
GG= Green Gg= Green Gg=yellow
Explanation:
Whenever there is a dominant allele it will ALWAYS show, the recessive alleles or lowercase letters show when they are paired together
The soil with the highest water-holding capacity in the triangle must be a soil that has a very high percentage of clay soil.
The question is incomplete but I will try to help you the much I can. There are different kinds of soil such as;
- Sandy soil
- Loamy soil
- Clay soil
- Silt Soil
The water holding capacity of the various kinds of soil are different. The soil with the least water holding capacity is sandy soil while the soil with the greatest water holding capacity is clay soil.
Hence, the soil with the highest water-holding capacity in the triangle must be a soil that has a very high percentage of clay soil.
