Four gases were combined in a gas cylinder with these partial pressures: 3.5 atm N2, 2.8 atm O2, 0.25 atm Ar, and 0.15 atm He.
Goryan [66]

Answer:

This can be solved using Dalton's Law of Partial pressures. This law states that the total pressure exerted by a gas mixture is equal to the sum of the partial pressure of each gas in the mixture as if it exist alone in a container. In order to solve, we need the partial pressures of the gases given. Calculations are as follows:

Explanation:

P = 3.00 atm + 2.80 atm + 0.25 atm + 0.15 atm

P = 6.8 atm

3.5 atm = x (6.8 atm)

x = 0.51

180m/173 Tl -> 180/173 Tl + ? Express your answer as a nuclear equation ​
Law Incorporation [45]

Answer: The nuclear equation is ^{180}_{173}Tl \rightarrow ^{180}_{173}Tl + ^{0}_{0}\gamma.

Explanation:

A nuclear reaction in which a heavy particle splits into another particle along with release of energy is called a nuclear fission reaction.

For example, ^{180}_{173}Tl \rightarrow ^{180}_{173}Tl + ^{0}_{0}\gamma

Here, energy is radiated in the form of gamma radiation.

Thus, we can conclude that the nuclear equation is ^{180}_{173}Tl \rightarrow ^{180}_{173}Tl + ^{0}_{0}\gamma.
