Answer 1

Incorrectly Formulated Salt Formulas

Here are the incorrectly formulated salt formulas from the options provided:

1. MgCl: This formula is incorrect because it does not specify the charge on the chloride ion. In ionic compounds, such as salts, the charges of the ions must be balanced to achieve electrical neutrality. The correct formula for magnesium chloride is MgCl2, where the magnesium ion has a charge of +2 and the chloride ion has a charge of -1.

2. FeNO3: This formula is incorrect because it does not follow the usual naming conventions for salts. In general, salts are named by combining the name of the cation (metal or positive ion) with the name of the anion (non-metal or negative ion). The correct formula for iron(II) nitrate is Fe(NO3)2, where the iron(II) ion has a charge of +2 and the nitrate ion has a charge of -1.

3. AlBr2: This formula is incorrect because it does not specify the charge on the bromide ion. The correct formula for aluminum bromide is AlBr3, where the aluminum ion has a charge of +3 and the bromide ion has a charge of -1.

To summarize, the incorrectly formulated salt formulas are: - MgCl (should be MgCl2) - FeNO3 (should be Fe(NO3)2) - AlBr2 (should be AlBr3)
