At what temperature will .100 moles of CO2 occupy 2.00L at 1.31 atm?

T = 319.5 K

Explanation: We will use the formula of Ideal Gas Law and derive for temperature. Ideal Gas Law is expressed in PV = nRT. The derived formula for T will be:

T = PV / nR

  = 1.31 atm (2.00 L) / 0.100 mole ( 0.082 L.atm/ mole.K )

  = 319.5 K

Cancel the units of atm, L and moles.

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .
