Carbon — pay attention to your periodic table trends
Answer:
metallic bonding
because it ids good conductor of electricity
Answer:
We'll have 13.85 grams of potassium
Explanation:
Step 1: Data given
Moles KBr = 0.46 mol
Molar mass KBr = 119.00 g/mol
Molar mass K = 30.10 g/mol
Step 2: The balanced equation
2KBr ⇆ 2K + Br2
Step 3: Calculate moles of K
For 2 moles KBr consumed we'll have 2 moles K and 1 mol Br2
For 0.46 moles KBr we'll have 0.46 moles K
Step 4: Calculate mass of K
Mass K = moles K * molar mass K
Mass K = 0.46 moles * 30.10 g/mol
Mass K = 13.85 grams
We'll have 13.85 grams of potassium
The answer is G Container 2
