Answer:

14.53ML

Explanation:

V1=218

V2=?

P2=15p1

USING BOYLE'S LAW

P1V1=P2V2

V2=P1V1/P2=P1(218ML)/15P1

=14.53ML

The chemical equation below is correctly balanced.
DIA [1.3K]

Answer:

44.8 L of O2 will react (option D)

Explanation:

Step 1: Data given

Number of moles of SO2 = 4.00 moles

STP = Pressure = 1 atm  and temperature = 273 K

Step 2: The balanced equation

2 SO2(g) + O2(g) → 2 SO3(g)

Step 3: Calculate moles of O2

For 2 moles SO2, we need 1 mol O2 to produce 2 moles SO3

For 4.00 moles SO2 we need 4.00 / 2 = 2.00 moles O2

Step 4: Calculate volume of O2

For 1 mol we have a volume of 22.4 L

V = (n*R*T)/ p

V = (2.00 * 0.08206 * 273)/p

V = 44.8 L

For 2.00 moles we have a volume of 2*22.4 = 44.8 L

44.8 L of O2 will react (option D)

Select the correct order of the GC components
s344n2d4d5 [400]
<span>Carrier Gas, Flow Controller, Column, Detector, Recorder

</span>First we have a cylinder containing the carrier gas. From there, the carrier gas goes to the flow controller, which determines how much carrier gas we are entering into the column (it doesn’t let more gas pass through). Then, the carrier gas enters the column, which is the most important part of the device. The sample enters the column from another place: the injector. Then, the sample and the carrier gas go together across the column. The interactions between the sample and the column will determine how fast each sample component goes through the column, and so: which component gets out earlier. So, at the end, you will have isolated each substance. Then, each one passes (alone) through the detector, which measures something about the sample – this information will let you know which substance it is. Finally, the recorder provides you with the information the detector has found. Nowadays, the recorder is a computer. In the “stone age” they just used a rudimentary printer.
