PLEASE HELP ME A sealed vessel containing carbon monoxide, Carbon dioxide, and oxygen and 0.65 atm for oxygen and 0.65atm for

1.15 atm

Explanation:

According to Dalton's law of partial pressures, the total pressure is the sum of all the partial pressures of the gases present in the mixture.

Therefore we have:

Total pressure = partial pressure of carbon monoxide + partial pressure of oxygen + partial pressure of carbon dioxide

We were given the following:

Total pressure = 2.45 atm

Pressure of oxygen = 0.65 atm

Pressure of carbon monoxide = x

Pressure of carbon dioxide = 0.65 atm

Therefore:

2.45 = x + 0.65 + 0.65

2.45 = x + 1.3

x = 2.45 - 1.3

x = 1.15 atm

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.

the answer is 0.42 is that is an option. this question provides no info
