Translate each of the following reactions into complete balanced chemical equations using international symbols & include states of matter at SATP. Assume pure states of matter unless otherwise indicated.
I really need help with this stuff please.
1. The reaction of magnesium and oxygen to form magnesium oxide is used to produce light in disposable flash bulbs.
2. Solid sodium sulfate reacts with carbon to form solid sodium sulfide(used to produce synthetic fabrics) and carbon dioxide.
Na2SO4 + 2 C = Na2S + 2 CO2
You simply convert the word equation into the symbols. Add the states in parentheses.
2Mg(s) + O2(g) ==> 2MgO(s)
The problem tells you what those are.
Na2SO4(s) + 2C(s) ==> Na2S(s) + 2CO2(g)
Doing these for you won't help you learn; if you will explain what you don't understand, perhaps I can point you in the right direction.
1. The reaction of magnesium and oxygen to form magnesium oxide is represented by the following balanced chemical equation:
2 Mg(s) + O2(g) → 2 MgO(s)
2. The reaction of solid sodium sulfate with carbon to form solid sodium sulfide (used to produce synthetic fabrics) and carbon dioxide is represented by the following balanced chemical equation:
Na2SO4(s) + 2 C(s) → Na2S(s) + 2 CO2(g)
To translate the given reactions into complete balanced chemical equations, we need to determine the formulas of the compounds, balance the atoms on both sides of the equation, and include the states of matter at SATP (Standard Ambient Temperature and Pressure).
1. The reaction of magnesium and oxygen to form magnesium oxide:
First, let's determine the formulas of the compounds involved:
- Magnesium: Mg (a solid)
- Oxygen: O₂ (a gas)
- Magnesium Oxide: MgO (a solid)
Now let's write the balanced chemical equation, while considering the law of conservation of mass (atoms) by ensuring the same number of atoms for each element on both sides of the equation:
2 Mg (s) + O₂ (g) → 2 MgO (s)
This balanced equation tells us that two atoms of magnesium react with one molecule of oxygen gas to produce two molecules of magnesium oxide, all in their solid states.
2. Solid sodium sulfate reacts with carbon to form solid sodium sulfide and carbon dioxide:
The given equation is already balanced and states the states of matter. The balanced equation is:
Na₂SO₄ (s) + 2 C (s) → Na₂S (s) + 2 CO₂ (g)
This balanced equation tells us that one molecule of solid sodium sulfate reacts with two carbon molecules to produce one molecule of solid sodium sulfide and two molecules of carbon dioxide, where sodium sulfate is solid, carbon is solid, sodium sulfide is solid, and carbon dioxide is a gas.
Remember to always double-check the formulas and balance equations properly to ensure accuracy.
