If two gases are present in a container, the total pressure in the container is equal to

Explanation:

The total pressure of two gases present in a container is equal to the sum of the pressures exerted by each individual gas.

That is the partial pressure law (Dalton's partial pressure law) and is a consequence of the fact that, since the gas particles are so small compared with the container, every gas in a mixture can be considered to occupy the entire volume of the container, driving to that the total pressure exerted by the mixture is equal to the sum of the partial pressures of the individual gases:

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
