The frequency stays the same it just gets louder
The compound responsible for the characteristic smell of garlic is allicin, that is having molecular formula C₆H₁₀OS₂.
Molar mass of C₆H₁₀OS₂=162.26 g mol⁻¹.
number of moles of C₆H₁₀OS₂=1 mol
So mass of C₆H₁₀OS₂ can be calculated as:


Given mass of the C₆H₁₀OS₂= 162 g
Answer:
Enzymes
Explanation:
Enzymes are proteins that can act as catalysts in the body.
Answer:
3.861x10⁻⁹ mol Pb⁺²
Explanation:
We can <u>define ppm as mg of Pb²⁺ per liter of water</u>.
We<u> calculate the mass of lead ion in 100 mL of water</u>:
- 100.0 mL ⇒ 100.0 / 1000 = 0.100 L
- 0.100 L * 0.0080 ppm = 8x10⁻⁴ mg Pb⁺²
Now we <u>convert mass of lead to moles</u>, using its molar mass:
- 8x10⁻⁴ mg ⇒ 8x10⁻⁴ / 1000 = 8x10⁻⁷ g
- 8x10⁻⁷ g Pb²⁺ ÷ 207.2 g/mol = 3.861x10⁻⁹ mol Pb⁺²
Benzene is more volatile.
