Answer:
at P = 101 KPa ⇒ S = 2.1 g/L
Explanation:
Henry's law:
∴ K: Henry's constant
∴ <em>C</em> is the concentration ≡ Solubiluty (S)
∴ S = (8.4 g/L)*(Kg/1000 g)*(1000 L/m³) = 8.4 Kg/m³
∴ P = (404 KPa)*(1000 Pa/KPa) = 404000 Pa
∴ Pa = Kg/ms²
⇒ S = K(404000 Pa) = 8.4 Kg/m³
⇒ K = 2.079 E-5 s²/m².......the henry's constant for this gas
at P = 101 KPa = 101000 Pa
⇒ S = (2.079 E-5 s²/m²)*(101000 Kg/ms²)
⇒ S = 2.1 Kg/m³ = 2.1 g/L
Salt water is considered a compound since water is H20 (conpound) and Salt with is NaCl.
The answer is B) pure water because pure water is a poor conductor of electricity.. thus a poor electrolyte
Explanation:
we know that 0.250 L = 0.250 dm3
molarity = concentration in dm3/ volume
molarity = 0.175/0.250 = 0.7 mol/dm3
Answer:
A chemical change because a temperature change occurred, the solid disappeared and a gas was produces
Explanation:
Magnesium reacts with hydrochloric acid releasing energy, and leading to the formation of magnesium chloride and hydrogen gas. This is represented by the equation below:
Mg₍s₎ + 2HCl₍aq)⇒ MgCl₂₍aq₎ + H₂₍g₎
