How do I write the skeleton equation representing the heating o f magnesium carbonate to produce solid magnesium oxide and carbon dioxide gas?
MgCO3 + heat ==> MgO + CO2
If I were in the classroom, I would write a delta sign over the arrow (for heat) but I can't do that on these boards.
To write the skeleton equation for the heating of magnesium carbonate to produce solid magnesium oxide and carbon dioxide gas, follow these steps:
Step 1: Write the chemical formulas of magnesium carbonate and magnesium oxide.
Magnesium carbonate: MgCO3
Magnesium oxide: MgO
Step 2: Identify the reactants (substances that undergo a chemical change).
Reactant: Magnesium carbonate (MgCO3)
Step 3: Identify the products (substances formed as a result of the chemical change).
Products: Solid magnesium oxide (MgO) and carbon dioxide gas (CO2)
Step 4: Write the skeleton equation using symbols and formulas.
Magnesium carbonate (MgCO3) → Magnesium oxide (MgO) + Carbon dioxide (CO2)
This is the skeleton equation representing the heating of magnesium carbonate to produce solid magnesium oxide and carbon dioxide gas.
To write the skeleton equation representing the heating of magnesium carbonate to produce solid magnesium oxide and carbon dioxide gas, you need to follow these steps:
Step 1: Determine the chemical formulas of the compounds involved.
- Magnesium carbonate: MgCO3
- Magnesium oxide: MgO
- Carbon dioxide: CO2
Step 2: Balance the equation by ensuring the number of atoms of each element is the same on both sides of the equation.
- Magnesium carbonate breaks down into magnesium oxide and carbon dioxide when heated.
- The decomposition reaction can be represented as:
MgCO3(s) ---> MgO(s) + CO2(g)
Step 3: Check if the equation is balanced by counting the number of atoms on each side.
- On the left side: 1 Mg, 1 C, 3 O
- On the right side: 1 Mg, 1 C, 3 O
Both sides have the same number of atoms for each element, so the equation is balanced.
So, the skeleton equation representing the heating of magnesium carbonate is:
MgCO3(s) ---> MgO(s) + CO2(g)
