Mad Scientist Mix-Up

100

A student named CO₂ as "Monocarbon dioxide." What is the error? Give the correct name.

You do not use the prefix "mono-" on the first element. The correct name is carbon dioxide.

200

A student wrote the formula for Magnesium chloride as MgCl. What is the error? Give the correct formula.

Magnesium has a +2 charge and chlorine has a -1 charge, so the correct formula is MgCl₂.

300

A student wrote the formula for sulfuric acid as HSO₄. What is the error? Give the correct formula.

Sulfate has a -2 charge, H₂SO₄

400

A lab report listed the compound as "Iron (III) chlorine." What is the error? Give the correct formula.

Monatomic anions end in "-ide". The correct name is Iron(III) chloride.

500

A student wrote the formula for Calcium hydroxide as CaOH₂. What is the error? Give the correct formula.

Hydroxide is a polyatomic ion (OH^-), so it needs parentheses when there is more than 1: Ca(OH)₂
