The combines law of gas is:
P1 * V1 P2 * V2
---------- = -----------
T1 T2
So, you can obtain many equivalent valid forms depending on the variable that you solve for.
These are some examples:
Solve for T1:
T1 = T2 * (P1 * V1) / (P2 * V2)
Solve for V2:
V2 = V1 * (T2 / T1) * (P1 / P2)
Solve for P1:
P1 = P2 * (T1 / T2) * ( V2 / V1)
Answer:
formation reaction.
Explanation:
Since the aluminum bromide produced in this reaction is formed from elements in their standard states, this is an example of a formation reaction.
Concentration is found by dividing the mass of solute by the volume of the solution. C = 4.2g/0.25 L. C= 16.8 g/L
Sun spots- dark circles on the sun’s surface that I believe are areas of cooler temperatures.
Solar flares- arcs of fire that leap from the sun’s surface. Nothing special, they’re a daily roumaine for the sun
Answer:
1023.75mmHg
Explanation:
V1 = 3.5L
P1 = 585mmHg
V2 = 2.0L
P2 = ?
To solve this question, we'll require the use of Boyle's law which states that the volume of a fixed mass of gas is inversely proportional to its pressure provided that temperature is kept constant.
Mathematically,
V = kP, k = PV
P1 × V1 = P2 × V2 = P3 × V3 = .......= Pn × Vn
P1 × V1 = P2 × V2
Solve for P2,
P2 = (P1 × V1) / V2
P2 = (585 × 3.5) / 2.0
P2 = 2047.5 / 2.0
P2 = 1023.75mmHg
The final pressure of the gas is 1023.75mmHg
