Answer: 287.8 cm3
Explanation:
Given that:
Initial volume of gas V1 = 350 cm3
Initial pressure of gas P1 = 740 mmHg
New volume V2 = ?
New pressure P2 = 900 mmHg
Since, pressure and volume are involved while temperature is constant, apply the formula for Boyle's law
P1V1 = P2V2
740 mmHg x 350 cm3 = 900mmHg x V2
V2 = (740 mmHg x 350 cm3) /900mmHg
V2 = 259000 mmHg cm3 / 900mmHg
V2 = 287.8 cm3
Thus, the gas will occupy 287.8 cubic centimeters at the new pressure.
I believe that the ice cube, being that it still has almost all of its properties, would still have a mass of 25 g after melting
Answer:
300 kPa
Explanation:
P2=P1V1/V2
You can check this by knowing that P and V at constant T have an inverse relationship. Hence, this is correct.
Answer:
I think it was a huge fish. umm not sure
Explanation:
The question needs:
In a 1 M solution of N₂H₄(aq), identify the relative molar amounts of these species. from most to least...
H₂O N₂H₅⁺~OH⁻ H₃O⁺ N₂H₄
H₂O is most
second N₂H₄
N₂H₅ and OH⁻ present in equal amount
H₃O⁺ is zero
because N₂H₄ is weak base it partially ionizes in water as following:
N₂H₄ + H₂O ⇄ N₂H₅⁺ + OH⁻
