Which best defines partial pressure in a mixture of gases? pressure that is exerted by all the gases of a mixture on the container pressure that is exerted by one gas as if it occupied a container by itself half of the pressure that is exerted by the gases of a mixture on the container sum of the individual pressures that are exerted by two or more gases

Answer;

Pressure that is exerted by one gas as if it occupied a container by itself

Explanation;Partial pressure refers to the pressure exerted by an individual gas in a mixture of gases.According to Dalton's law of partial pressure, the total pressure of a mixture of gases is equivalent to the sum of the partial pressures of the component gases.Therefore; The partial pressure of one gas in a mixture of gases, contained in a given volume, is the pressure that one gas would exert if it occupied the entire volume all by itself.

For cyclohexane compounds drawn in a chair conformation:   -axial bonds are vertical  -equatorial bonds are parallel to two bonds within the ring.  thus, as i assume the chair conformation is drawn:   -the x group is in an axial position, as are the five other vertical bonds.  -three axial bonds are on the top face of the ring  -the other three axial bonds are on the bottom face  the position of the second substituent on each ring carbon is equatorial.  gauche groups must be on an adjacent carbon such as carbon 6 and carbon 2, and also gauche groups are rotated by 60 degrees relative to each other.  drawing the newman projections for c1–c2 and c1–c6 aids in visualizing the groups that are gauche to the y group on c1.  click this link and watch some academic videos that may you more understand the topic
