Answer 3

It looks like you've provided chemical formulas for two compounds: Fe2O3 and NaHSO4. These are chemical formulas for iron(III) oxide and sodium hydrogen sulfate, respectively.

1. Fe2O3:

• Chemical Name: Iron(III) oxide
• Common Name: Ferric oxide or Hematite
• Composition: It consists of two iron (Fe) atoms and three oxygen (O) atoms per formula unit.
• Appearance: Reddish-brown solid.
• Uses: Iron(III) oxide is used as a pigment in paints, ceramics, and cosmetics. It's also an important component in the production of iron and steel.

2. NaHSO4:

• Chemical Name: Sodium hydrogen sulfate
• Composition: It consists of one sodium (Na) atom, one hydrogen (H) atom, one sulfur (S) atom, and four oxygen (O) atoms per formula unit.
• Appearance: Usually a white crystalline solid.
• Uses: Sodium hydrogen sulfate is used in various industrial processes including paper manufacturing, textile dyeing, and as an electrolyte in certain types of batteries.
