Oxygen and chlorine gas are mixed in a container with partial pressures of 52 kPa and 60 kPa, respectively. What is the total pressure inside the container?

Explanation:

Hello,

In this case case, the Dalton's law is useful to compute the total pressure in terms of the partial pressure of the present gases:

Best regards.

i did this but i forgot how to do it

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6
