What pressure (in atm) is required to contain 0.034 moles of oxygen gas in a 5.1 L container at a temperature of 25.00C
kherson [118]

Answer:

0.16 atm

Explanation:

Let's look at the formula PV=nRT. First of all, T should be in kelvin, so let's add 273. Now solve for P so we get P = nRT/V.

Now let's plug these in...

P = (0.034 mol)(0.08206 L atm mol^-1 K^-1)(298 K)/5.1 L

After solving and rounding to sig figs we get 0.16 atm

25cm3 of gas at 1 atm has a temperature of 20 degree celsis .
Andreas93 [3]

Answer:

1.28 atm

Explanation:

To solve this problem, you need to use the gas laws, more specifically the Combined Gas Law. It is P1V1/T1 = P2V2/T2. Simply plug your values in. But be careful! Make sure you convert your 20 degree C and 28 deg C to Kelvin, as that it the only temperature scale the Gas Laws work with. Upon plugging in your values, you get approximately 1.28 atm.

Which of these is the BEST way to manage a natural resource?
Solnce55 [7]

The answer is C.

This can be concluded by looking at the other answers and eliminating them one-by-one.

Managing (Or conserving) a natural resource means to sustain it and use it as efficiently as possible.

With this in mind, we can look and eliminate certain answers.

A is incorrect because driving a car uses gas, a natural resource. By using as much gas as possible, the resource would be wasted instead of conserved.

B is incorrect because water is a natural resource. Once again, by using this, it's wasted where it could be conserved.

C is correct because planting trees would conserve the resource; by consistently planting trees where they're cut, the chances of running out of wood decrease.

D is incorrect because both the water and the creatures that live inside it are natural resources. By dumping toxic waste, these resources are wasted where it could be conserved.

Hope this helped you! :)
