Determine the temperature of 2.49mol of a gas contained in a 1.00L vessel at a pressure of 1.41atm. A. 345K

B. 159K

C. 18.7K

D. 6.90K

T=6.90 K

Explanation:

For this problem, you would use Ideal Gas Law.

P=pressure

V=volume

n=moles

R=ideal gas constant

T=temperature (in Kelvin)

We can fill in these values with what we are given.

P=1.41 atm

V=1.00 L

n=2.49 mol

R=0.08206 Latm/Kmol

T=?K

Since we are looking for T, we can get T alone.

With significant figures, we get .

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.

consider the reaction below.

 no rx

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m

what is the equilibrium constant for the given reaction?
