Answer:
The HCl will dissolve the calcium readily
Explanation:
HCl will react with d calcium, dissolving it to produce Hydrogen gas
Answer:
255.6
Explanation:
If you have 12 gallons and get 21.3mpg,
-Multiply 21.3 by 12
-you can travel 255.6 miles before running out of gas.
-If you need to estimate, round up to 256 miles.
Answer:
Explanation:
Henry's law states that the amount of dissolved gas in a liquid is proportional to its partial pressure above the liquid
number of moles of cyclopropane = 1.84 g / 42.08 g/mol = 0.044 mol
number of mole of water = 1010000 g / 18.02 g/mol = 56048.83 mol
mole fraction of cyclopropane = mole of cyclopropane / ( mole of water + mole of cyclopropane) = 0.044 mol / 56048.87 = 7.85 × 10⁻⁷
P cyclopropane = k henry × mole fraction of cyclopropane = 4273 atm × 7.85 × 10⁻⁷ = 0.00335 atm
b) number of cyclopropane molecules present in each cubic centimeter = ( 0.044 mol / 1010) × 6.022 × 10 ²³ / 1000 cm³ = 2.623 × 10 ¹⁶ molecules in cm³
