Areal gas is in a regime in which it is accurately described by the ideal gas equation of state. 27.1 g of the gas occupies 50.0 l at a pressure of 0.500 atm and a temperature of 449 k. identify the gas.

Argon

Explanation:

Given data

We can find the molar mass (M) of the gas using the ideal gas equation.

P × V = n × R × T

P × V = m/M × R × T

M = m × R × T/P × V

M = 27.1 g × (0.08206 atm.L/mol.K) × 449 K/ 0.500 atm × 50.0 L

M = 39.9 g/mol

If the gas is monoatomic, the one with a molar mass of 39.9 g/mol is argon.

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )

answer: any goods being imported from another country may be subject to issued by the federal government are tariffs

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them
