Question

Write the chemical formulas to the following three reactants1) silver nitrate reacting with aqueous sodium chloride2) magnesium reacting with oxygen gas3) ammonium dichromate crystals heated

Answer 1

1) AgNO₃, NaCl

2) Mg, O₂

3) (NH₄)₂Cr₂O₇

Step-by-step explanation

The chemical formulas for the following three reactants are:

1) silver nitrate reacting with aqueous sodium chloride.

Silver nitrate is AgNO₃

Sodium chloride is NaCl

And the equation for the reaction is: AgNO₃ + NaCl (aq) → NaNO₃ + AgCl

2) magnesium reacting with oxygen gas.

Magnesium is Mg

Oxygen gas is O₂

The equation for the reaction is: 2Mg + O₂ → 2MgO

3) ammonium dichromate crystals heated.

Ammonium dichromate is (NH₄)₂Cr₂O₇

The chemical equation for the reaction is: (NH₄)₂Cr₂O₇ (s) + Heat → Cr₂O₃ + N₂ + 4H₂O
