A scuba tank is being prepared for a deep sea dive 9 atms of He, 1.5 atms of Nitrogen gas and 6 atms of oxygen gas are added to the tank. What is the total pressure?

9+6+1.5 =16.5atm

Explanation:

total pressure is equal to the sum of the partial pressures.

P(He) + P(N2) + P(O2) =P(Total)

9atm + 1.5atm + 6atm = 16.5 atm

the correct answer is answer a. a mixture

no other options make sense

hope this

have a great day : )

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.

⇌(double head arrow) means reversible reaction).
