Icy water is just water.
It is a compound.
Answer: 252.5 kPa
Explanation:
Given that:
initial volume of gas V1 = 5.00 L
initial pressure of gas P1 = 101 kPa.
new Volume V2 = 2.00 L
new pressure P2 = ?
Since, only pressure and volume are involved, apply the formula for Boyle's law
P1V1 = P2V2
101 kPa x 5.0L = P2 x 2.00L
505 = P2 x 2.00L
P2 = 505/2.00
P2 = 252.5 kPa
Thus, the new pressure of gas inside the piston is 252.5 kPa
Answer:
The most important constraint felt in the progress of organic farming is the inability of the government policy making level to take a firm decision to promote organic agriculture. willingness on the part of the farming community.
Explanation:
Using Charles's law; which states that the volume of an ideal gas is directly proportional to the absolute temperature at constant pressure.
That is; V α T
Hence; V1/T1 = V2/T2 = constant
V2 = V1 × (T2/T1)
= 250 × (350/300) = 291.67 mL
Therefore; the new volume will be 291.67 mL
These are buffer systems (solutions of substances) with a steady concentration of hydrogenium ions. At addition to such solution of a small amount of acid or alkali does not change рН.
For example:
CH₃COOH + CH₃COONa acetate buffer
KH₂PO₄ + K₂HPO₄ potassium phosphate buffer
