The answer is 1.6 atm. Let's first calculate the mole fraction of gas Y.
The mole fraction (x) is: x = n1/n, where n1 is a number of moles of an
individual gas in a mixture and n is total moles of the gas mixture. We
know that n1 of gas Y is 6.0 mol (n1 = 6.0 mol) and that there are in
total 8. mol of the gas mixture (n = 2.0 + 6.0 = 8.0 mol). Now calculate
the mole fraction of gas Y. x = 6.0/8.0 = 0.75. Now, let's use the mole
fraction of gas Y (x) and the total pressure (P) to calculate the
partial pressure of gas Y (P1): x = P1/P. P1 = x * P. If x = 0.75 and P =
2.1 atm, then the partial pressure of gas Y is: P1 = 0.75 * 2.1 atm =
1.6 atm.
Answer:
butyne
Explanation:
alkane, alkene, and alkyne are all examples of hydrocarbons.
butyne = alkyne
air blows at the base of circulation cells from high pressure to low pressure
When a hypothesis is testable, it means that it's possible to see whether the prediction is true or not. Testing a hypothesis can include conducting experiments, collecting data and making observations.
Ionic compound generally has high melting point due to the strong ionic bond. It is also hard but brittle because repulsion between oppositely charged ions will occur if force is applied. It is soluble in water but insoluble in non-aqueous solvent. It can only conduct electricity when molten or in aqueous solution and undergo chemical decomposition upon conducting electricity.
