The atom will lose three valence electrons.
<h3>What is meant by valence electron ?</h3>
- A valence electron is an electron that is part of an atom's outer shell in chemistry and physics. If the outer shell is open, the valence electron can take part in the creation of a chemical bond.
- Each atom in the bond contributes one valence electron to create a shared pair in a single covalent bond.
- The chemical properties of an element, such as its valence—whether it can bond with other elements and, if so, how readily and with how many—can be affected by the presence of valence electrons. In this way, the electronic configuration of an element greatly influences its reactivity.
- A valence electron for a main-group element can only be found in the outermost electron shell; for a transition metal, it can also be found in an inner shell.

The inventor of the cotton gin in Eli Whitney
Answer:
C₆H₁₂O₆ and O₂
Explanation:
To know which option is correct, it important that we know the concepts of chemical equation .
A chemical equation gives us an expression of a chemical reaction in terms of symbols and formula. There are two sides to every equation. The side bearing the reactant and the side bearing the product.
The reactant is located on the left side and the product is located on the right side.
Reactant —> Product
With the above information, let us answer the question given above.
6CO₂ + 6H₂O —> C₆H₁₂O₆ + 6O₂
The products are located on the right side of the equation.
Thus, the products of the reaction is C₆H₁₂O₆ and O₂
Answer:

First you need to calculate the number of moles of aluminium and copper chloride.
number of moles = mass / molecular weight
moles of Al = 512 / 27 = 19 moles
moles of CuCl = 1147 / 99 = 11.6 moles
From the reaction you see that:
if 2 moles of Al will react with 3 moles of CuCl
then 19 moles of Al will react with X moles of CuCl
X = (19 × 3) / 2 = 28.5 moles of CuCl, way more that 11.6 moles of CuCl wich is the quantity you have. So the copper chloride is the limiting reagent.
