1. Rewrite the word equation as formula equation:
Aluminum + copper (II) chloride= aluminum chloride + copper
2. What is not equal in these chemical formula equations:
a.) magnesium + oxygen = magnesium oxide
B.) water = hydrogen + oxygen
c.)methanol +oxygen = carbon dioxide + water
D.) aluminum + copper (II) chloride= aluminum chloride + copper
Al is +3 here
2 Al + 2CuCl2 --> 2AlCl3 + 3Cu
I do not understand what the second question means? Balance the equations or what?
1. To rewrite the word equation as a formula equation, we need to represent each element with its corresponding chemical symbol and balance the equation based on the Law of Conservation of Mass.
The given word equation is:
Aluminum + copper (II) chloride = aluminum chloride + copper
Rewriting this equation in a formula equation format, we have:
2Al + 3CuCl2 = 2AlCl3 + 3Cu
In this formula equation, we use chemical symbols to represent each element: Al for aluminum, CuCl2 for copper (II) chloride, AlCl3 for aluminum chloride, and Cu for copper. The numbers in front of each element or compound are the coefficients that balance the equation, ensuring that the number of atoms of each element remains the same on both sides of the equation.
2. The chemical formula equations can be evaluated by checking if the number of atoms for each element is balanced on both sides of the equation.
a.) magnesium + oxygen = magnesium oxide
On the left side, we have: 1 Mg atom + 1 O atom
On the right side, we have: 1 Mg atom + 1 O atom
The number of atoms for each element is the same on both sides, so this equation is balanced.
b.) water = hydrogen + oxygen
On the left side, we have: 2 H atoms + 1 O atom
On the right side, we have: 2 H atoms + 1 O atom
The number of atoms for each element is the same on both sides, so this equation is balanced.
c.) methanol + oxygen = carbon dioxide + water
On the left side, we have: 4 H atoms + 1 C atom + 1 O atom
On the right side, we have: 2 H atoms + 1 C atom + 3 O atoms
The number of atoms for each element is not the same on both sides, so this equation is not balanced.
D.) aluminum + copper (II) chloride = aluminum chloride + copper
On the left side, we have: 2 Al atoms + 3 Cu atoms + 6 Cl atoms
On the right side, we have: 2 Al atoms + 6 Cl atoms + 3 Cu atoms
The number of atoms for each element is the same on both sides, so this equation is balanced.
Therefore, the chemical formula equation that is not equal is c.) methanol + oxygen = carbon dioxide + water.
