1 mole of butane uses 4.5 moles of oxygen
0.1 mole of butane will use = 0.1 * 4.5 = 0.45 moles
P = 100 kPa = 100,000Pa
n = 0.45
T = 295 K
V = ?
Using PV = nRT
⇒ 100,000 * V = 0.45 * 8.314 * 295
⇒100,000 V = 1103.68
⇒ V = 1103.68/100,000 m³
⇒ V = 1103.68/100,000 * 1000 dm³
⇒ V = 11.036 dm³
You need 11.036 dm³ oxygen.
Answer:
the experimental group would be the teachers who recieved the candy
control group would be the teachers who dont get any candy
<em>Explanation:</em>
experimental group is the group that receives the test variable being tested in this case the variable being the candy
and the control group is the group who doesn't receive the variable
purpose of having a control is to rule out other factors which may influence the results of an experiment.
