Aflask contains a mixture of n2 and o2 at stp. if the partial pressure exerted by the n2 is 40.0 kpa, the partial pressure of o2 is?

The partial pressure of is 61.325 kPa.

Explanation:

STP is the abbreviation for Standard Temperature and Pressure. The standard temperature is 273 K and the standard pressure is 1 atm pressure.

1 atm = 101.325 kPa

According to Dalton's law, the total pressure of a mixture of gases is the sum of individual pressures exerted by the constituent gases.

Thus

Given:  

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.

cytokinesis is the splitting of a cell membrane to form 2 identical daughter cells. it's similar to mitosis as both cells have identical copies of dna and cytokinesis is a step in the mitotic cycle.
