(Unsure if this helped but hope it did!)
Answer:
A: Cu; B: Mg; C: Mg + Cu²⁺ ⟶ Mg²⁺ + Cu
Explanation:
The left-hand side of the cell diagram is where oxidation occurs (the anode).
Mg ⟶ Mg²⁺ + 2e⁻
So, Mg is the anode.
The right-hand side of the cell diagram is where reduction occurs (the cathode)
Cu²⁺ + 2e⁻ ⟶ Cu
As the copper ions hit the copper cathode, they remove electrons from the metal and become copper atoms. Since the metal has lost electrons, Cu is the positive electrode.
To get the overall reaction, we add the two half-reactions,
Mg ⟶ Mg²⁺ + 2e⁻
<u>Cu²⁺ + 2e⁻ ⟶ Cu </u>
Mg + Cu²⁺ ⟶ Mg²⁺ + Cu
Answer:
A- Energy from sunlight becomes glucose during photosynthesis
Explanation:
The law of conservational photosynthetic energy states that atoms cannot be created nor destroyed; the atoms can only be rearranged into new molecules and ions. This implies that the enzymes in photosynthesis are aided by energy to transform into glucose, which the plant needs.
Answer:
alkali metal
Explanation:
The alkali metals in period 4 will have the lowest ionization energy of the elements in the period.
Across a period ionization energy increases progressively from left to right due to decreasing atomic radii caused by the increasing nuclear charge which is not compensated for by successive electronic shells.
- Ionization energy is the energy needed to remove the most loosely bound electrons of an atom in the gas phase in the ground state.
- The measure of the readiness of an atom to lose an electron is the ionization energy.
Down a group, it decreases.
Yes it is always changing, as time moves on new technological advancements are made. This makes it possible for new ideas to be created. For example the depiction of an atom went through many stages throughout the years in order to find out our current final version. New scientists and new ideas can add on to older ones, making explanations that make more scientific sense.
