Quick will mark the general formula for an acid is where stands for hydrogen, n stands for the of hydrogen ions, and stands for the monatomic or polyatomic (fill in the blanks)

The general formula for an acid is HnX where H stands for hydrogen, n stands for the number of hydrogen ions, and X stands for the monatomic or polyatomic ions ( since those are negative charged ions, they are called anions).

Explanation:

The general formula for an acid is HnX) where H stands for hydrogen, n stands for the number of hydrogen ions, and X stands for the monatomic or polyatomic ions ( since those are negative charged ions, they are called anions).

An example is H2SO4, also called sulfuric acid

It shows that H2SO4 has 2 hydrogen atoms, so in the formula HnX n=2

X fro H2SO4 is SO42-, it's a polyatomic ion. Since it has a negative charge of 2- it needs 2 hydrogen atoms to bind and form H2SO4

c. heat could easily travel through the molecules in the air and escape/enter the flask. removing the air slows down the heat transfer.
