1. Calcium and water react to yield calcium hydroxide and hydrogen.

Translate the chemical names and write the unbalanced, skeletal equation.

Write the overall balanced chemical equation.

Explain what the balanced equation means in words (in terms of moles or molecules).

1. Silicon dioxide and hydrochloric acid react to produce water and silicon tetrachloride.
2. Translate the chemical names and write the unbalanced, skeletal equation.
3. Write the overall balanced chemical equation.

Explain what the balanced equation means in words (in terms of moles or molecules).

Answer 1

a). NO2 + H₂O ==> HNO₃ + NO unbalanced skeletal equation

b). 3NO₂ + H₂O ==> 2HNO₃ + NO balanced equation

c). Three moles of nitrogen dioxide plus one mole of water produce 2 moles of nitric acid and one mole of nitrogen monoxide.

a). SiO₂ + HCl ==> H₂O + SiCl₄ unbalanced skeletal equation

b). SiO₂ + 4HCl ==> 2H₂O + SiCl₄ balanced equation

c). One mole of silicon dioxide plus 4 moles of hydrochloric acid prodce 2 moles of water plus one mole of silicon tetrachloride
