HELP ME WITH ONE OR BOTH OF THESE QUEATIONS PLEASEEEE
marta [7]

Answer:

2. 181.25 K.

3. 0.04 atm.

Explanation:

2. Determination of the temperature.

Number of mole (n) = 2.1 moles

Pressure (P) = 1.25 atm

Volume (V) = 25 L

Gas constant (R) = 0.0821 atm.L/Kmol

Temperature (T) =?

The temperature can be obtained by using the ideal gas equation as illustrated below:

PV = nRT

1.25 × 25 = 2.1 × 0.0821 × T

31.25 = 0.17241 × T

Divide both side by 0.17241

T = 31.25 / 0.17241

T = 181.25 K

Thus, the temperature is 181.25 K.

3. Determination of the pressure.

Number of mole (n) = 10 moles

Volume (V) = 5000 L

Temperature (T) = –10 °C = –10 °C + 273 = 263 K

Gas constant (R) = 0.0821 atm.L/Kmol

Pressure (P) =?

The pressure can be obtained by using the ideal gas equation as illustrated below:

PV = nRT

P × 5000 = 10 × 0.0821 × 263

P × 5000 = 215.923

Divide both side by 5000

P = 215.923 / 5000

P = 0.04 atm

Thus, the pressure is 0.04 atm

A model of fossils formed on land, on the shore, and in water was set up in Ms. Bill’s classroom. One of the students commented
zubka84 [21]

Answer:

d.- The model does not provide information about the type of rock in which fossils form.

Explanation:

The fossils can be located in different parts like on land, shore and water. But, they were formed at different time, that means, they live in different ages, that is the reason why the model need to include the type of rock. Remember fossil form at different ages and with the pass of time different layers of rock formed.

Hope this info is useful.
