Answer:
1.) 13 g C₄H₁₀
2.) 41 g CO₂
Explanation:
To find the mass of propane (C₄H₁₀) and carbon dioxide (CO₂), you need to (1) convert mass O₂ to moles O₂ (via molar mass), then (2) convert moles O₂ to moles C₄H₁₀/CO₂ (via mole-to-mole ratio from equation coefficients), and then (3) convert moles C₄H₁₀/CO₂ to mass C₄H₁₀/CO₂ (via molar mass). It is important to arrange the ratios in a way that allows for the cancellation of units. The final answers should have 2 sig figs to match the sig figs of the given value.
Molar Mass (C₄H₁₀): 4(12.011 g/mol) + 10(1.008 g/mol)
Molar Mass (C₄H₁₀): 58.124 g/mol
Molar Mass (CO₂): 12.011 g/mol + 2(15.998 g/mol)
Molar Mass (CO₂): 44.007 g/mol
Molar Mass (O₂): 2(15.998 g/mol)
Molar Mass (O₂): 31.996 g/mol
2 C₄H₁₀ + 13 O₂ ----> 8 CO₂ + 10 H₂O
48 g O₂ 1 mole 2 moles C₄H₁₀ 58.124 g

True
Explanation:
The position of sodium on the periodic table makes the element a solid at room temperature is very correct.
- Sodium is an elements with 11 electrons in its shell.
- It is located in group 1 on the periodic table because it contains an outer valence electron.
- In a free state Na metal, the atoms exhibit metallic bonding.
- Metallic bonding is responsible for the solid nature of this alkali metal at room temperature.
- It is highly reactive because it has just one valence electron.
- Metals are usually found left of the periodic table.

If your bike isn't the right size, your legs could be rubbing up against the seat of your bike. The friction can chafe the skin on your legs. If you were to crash your bike, skidding on the ground can cause anywhere from minor scrapes to serious friction burns.
