Ionic compounds
<h3>
Explanation:</h3>
What are ionic compounds?
- Ionic compounds are compounds that are formed due to ionic bonds between atoms.
- Ionic bonds are formed between metallic atoms and non-metallic atoms.
What are examples of ionic compounds?
- Examples of ionic compounds include, KCl, NaBr, MgCl₂, etc
How do ionic compound ionize in water?
- Ionic compounds ionizes when dissolved in water to form mobile ions.
- When dissolved in water they may serve as electrolytes due to the presence of free ions which will be responsible for conduction of electricity.
- For example, NaCl ionizes to form Na⁺(aq) and Cl⁻(aq).
Answer:
5.2g copper (Cu) => 0.082 moles copper (2 sig.figs.)
Explanation:
mole conversions:
grams to moles => divide by formula wt.
moles to grams => multiply by formula wt.
gas volumes to moles => divide volume by 22.4Liters/mole (STP conditions only)
This problem:
mass to moles => divide by formula wt.
mass = 5.2g = 5.2g/63.5g/mole = 0.082 moles copper (2 sig.figs.)
Answer:
Because they are renewable energy
