Answer:
The dispersed particles are spread evenly throughout the dispersion medium, which can be a solid, liquid, or gas. Because the dispersed particles of a colloid are not as large as those of a suspension, they do not settle out upon standing.
Explanation:
Virtually all acids release hydrogen ions (or protons) in the water
Answer: 211 kPa
Explanation:
Given that,
Original pressure of gas (P1) = 125 kPa
Original volume of cylinder (V1) = 760 cm3
New pressure of gas (P2) = ?
New volume of cylinder (V2) = 450 cm3
Since pressure and volume are given while temperature is held constant, apply the formula for Boyle's law
P1V1= P2V2
125 kPa x 760 cm3= P2 x 450 cm3
95000 kPa•cm3 = 450 cm3•P2
Divide both sides by 450 cm3
95000 kPa•cm3/450 cm3 = 450 cm3•P2/450 cm3
211.1 kPa = P2
[Round the value of P2 to 3 significant numbers. Hence, P2 becomes 211 kPa]
Thus, the new pressure within the cylinder is 211 kPa
