what is the balanced molecular formula and state for this equation
Mg+Cr(C2H3O2)3=
3Mg+2Cr(C2H3O2)3 > 3Mg(C2H3O2)2 + 2Cr
To determine the balanced molecular formula and state for the equation: Mg + Cr(C2H3O2)3 = ?, we need to understand the chemical formulae and the rules of balancing chemical equations.
The chemical formula for magnesium is Mg. The chemical formula for chromium acetate is Cr(C2H3O2)3.
First, let's balance the equation by following these steps:
Step 1: Identify the number of each element on both sides of the equation.
On the left-hand side, we have 1 Mg atom and on the right-hand side, we have 1 Cr atom.
For the acetate group (C2H3O2), we have 3 carbon atoms, 6 hydrogen atoms, and 6 oxygen atoms on the right-hand side.
Step 2: Balance the elements one by one.
Start with the carbon atoms. We have 3 carbon atoms on the right-hand side but none on the left-hand side. To balance the carbon, we need to add a coefficient of 3 in front of Mg, resulting in 3Mg.
Next, balance the hydrogen atoms. We have 6 hydrogen atoms on the right-hand side but none on the left-hand side. To balance the hydrogen, we need to add a coefficient of 6 in front of H2O, resulting in 3Mg + 6H2O.
Finally, balance the oxygen atoms. We have 6 oxygen atoms from the acetate group on the right-hand side, but no oxygen atoms on the left-hand side. To balance the oxygen, we need to add a coefficient of 3 in front of MgO, resulting in 3Mg + 6H2O + 3MgO.
The balanced equation is:
3Mg + Cr(C2H3O2)3 = 3Mg + 6H2O + 3MgO
Now, let's determine the state of the compounds in the equation. The given equation does not specify the state of each compound involved, so we need additional information.
Mg is typically a solid (s) at room temperature and pressure.
Cr(C2H3O2)3, which is chromium acetate, is often in a solid state (s).
Therefore, the balanced molecular formula and state for the equation:
3Mg (s) + Cr(C2H3O2)3 (s) = 3MgO (s) + 6H2O (l) is:
3 moles of solid magnesium react with 1 mole of solid chromium acetate to produce 3 moles of solid magnesium oxide and 6 moles of liquid water.
To determine the balanced molecular equation and state for the given reaction Mg + Cr(C2H3O2)3, we first need to identify the compounds involved.
Mg → Magnesium
Cr(C2H3O2)3 → Chromium(III) acetate
Next, we can write the balanced molecular equation by swapping the cations and anions:
Mg + Cr(C2H3O2)3 → Mg(C2H3O2)2 + Cr
Finally, let's determine the state of the compounds. Generally, metals like magnesium (Mg) are solid, while salts like chromium(III) acetate (Cr(C2H3O2)3) are often found in aqueous solutions.
Therefore, the balanced molecular equation with states is:
Mg(s) + Cr(C2H3O2)3(aq) → Mg(C2H3O2)2(aq) + Cr(s)
