A sample of argon, Ar, has a volume of 5.40 L with an unknown pressure. The gas has a volume of 9.73 L when the pressure is 3.62 atm, with no change in temperature and amount of gas. What was the initial pressue in atm of the gas?
O a. 6.523 atm
O b. 6.52 atm
Oc 2.009 atm
Od. 2,01 atm

Explanation:

The initial pressure can be found by using the formula for Boyle's law which is

Since we are finding the initial pressure

From the question we have

We have the final answer as

Hope this helps you

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
