in an experiment, 24g of magnesium metal reacts with 73g of hydrogen chloride solution to produce hydrogen gas and 95g of magnesium chloride. Write the word, skeletal and balance eqautions
I've ignored the numbers since they seem to be in stoichiometric quantities and no excess of either reagent is left.
magnesium metal plus hydrochloric acid yields magnesium chloride + hydrogen.
Mg + HCl ==> MgCl2 + H2
Mg + 2HCl ==> MgCl2 + H2
Mg + 2HCl ==> H2 + MgCl2
To find the word, skeletal, and balanced equations for this reaction, we need to first understand the reactants and products involved.
Reactants:
- Magnesium metal (Mg)
- Hydrogen chloride solution (HCl)
Products:
- Hydrogen gas (H2)
- Magnesium chloride (MgCl2)
Now let's write the equations step by step:
1. Word equation:
Magnesium metal + Hydrogen chloride solution → Hydrogen gas + Magnesium chloride
2. Skeletal equation:
Mg + HCl → H2 + MgCl2
3. Balanced equation:
To balance the equation, we need to ensure that the number of atoms of each element on both sides of the equation is equal.
Mg + 2HCl → H2 + MgCl2
The balanced equation shows that 1 atom of magnesium reacts with 2 molecules of hydrochloric acid to produce 1 molecule of hydrogen gas and 1 molecule of magnesium chloride.
To write the word equation:
Magnesium metal + Hydrogen chloride solution → Hydrogen gas + Magnesium chloride
To write the skeletal equation:
Mg + HCl → H2 + MgCl2
To balance the equation:
2Mg + 2HCl → H2 + 2MgCl2
