Solution. We can draw the Lewis structure of any covalent molecule by following the six steps discussed earlier. In this case, we can condense the last few steps, since not all of them apply. Calculate the number of valence electrons: XeF 2: 8 + (2 × 7) = 22XeF 6: 8 + (6 × 7) = 50.

Nov 21, 2017 · So its state symbol will be $\text{(aq)}$. Hydrogen on the other hand is a gas (at room temperature and above) and highly insoluble in water: it will leave the reaction as gas and its state symbol will be $\text{(g)}$. So without knowing the physical/chemical properties of the reagents/reaction products, the state symbols cannot be determined.

Aqueous is a state of being dissolved in water and uses the state symbol (aq) which originated from the Latin word for water – Aqua. This word can often be found at number one on the ingredients lists of inedible items like shampoos and conditioners. Water is an example of a compound comprised of hydrogen and oxygen bonded covalently.
Write the balanced symbol equation, including state symbols, for the reaction. Answer: Step 1: Work out the formula and state symbols of the reactants and products to construct an unbalanced symbol equation: Aluminium is a solid metal, like other pure metals, it is an element so its formula is the same as its chemical symbol: Al (s)
