The oxidation number of V and Al in each ion is +3 and +4 respectively.
<h3>What is oxidation number in chemistry?</h3>
oxidation number, also called oxidation state, the total number of electrons that an atom either gains or loses in order to form a chemical bond with another atom.
<h3 /><h3>Why is it called oxidation number?</h3>
The term oxidation was first used by Antoine Lavoisier to signify the reaction of a substance with oxygen. Much later, it was realized that the substance, upon being oxidized, loses electrons, and the meaning was extended to include other reactions in which electrons are lost, regardless of whether oxygen was involved.

Answer:
True
Explanation:
Theories are not laws and so new scientific evidence could render them as untrue. For example, the big bang theory on how the universe has started is just a theory. Current evidence backs it up, but if future evidence disproves it, the theory will be replaced by a different one.
Answer:
Part A. Mass = 0.12 g of NaCl
Part B. Mass = 0.41 g of Pb
Explanation:
Part A. We verify the moles
2×10⁻³ moles of NaCl
Let's determine the molar mass → Molar mass Na + Molar mass Cl
23 g/mol + 35.45 g/mol = 58.45 g/mol
We convert moles to g → 2×10⁻³ mol . 58.45 g/mol = 0.11 g
Part B. → 2×10⁻³ moles of Pb; Molar mass = 207.2 g/mol
We convert moles to g → 2×10⁻³ mol . 207.2 g/mol = 0.41 g of Pb

<h2>The required "option is a) shift rightward".</h2>
Explanation:
According to the condition given that is when there is a decrease in the price of corn, the supply of ethanol will increase as there will be more production of ethanol.
- If the curve of supply shifts towards left it means there is a decrease in the production as well as supply of the ethanol.
- If the curve of supply shift towards right it means there is the an increase in the production of ethanol.
- If the curve of supply is being unchanged or flattered it signifies that there will be more production of ethanol and supply will be less hence there will be no profit.
- Hence, the supply curve will shift rightward.
