Potassium reacts with magnesium bromide to form potassium bromide and magnesium.
Which equation correctly represents the statement?
2K+MgBr_2→2KBr+Mg
K+MgBr→KBr+Mg
K+MgBr_2→KBr_2+Mg
2KBr+Mg→2K+MgBr_2
A?
yes
Thank you :)
The correct equation that represents the statement is:
2K + MgBr2 → 2KBr + Mg
The correct equation that represents the statement is:
2K + MgBr2 → 2KBr + Mg
To understand why this equation is correct, let's break it down:
- The reactants are potassium (K) and magnesium bromide (MgBr2).
- The potassium (K) will react with the magnesium bromide (MgBr2) to form potassium bromide (KBr) and magnesium (Mg).
- Since there are two potassium atoms on the left side of the equation, there must be two potassium bromide molecules (2KBr) on the right side.
- The equation is balanced when the number of atoms on both sides is equal. In this case, the equation is balanced with 2 potassium atoms, 2 bromine atoms, and 1 magnesium atom on each side.
Therefore, the correct equation is 2K + MgBr2 → 2KBr + Mg, as seen in option A.
