Propane a fuel that is used in camp stoves produces carbon dioxide and water vapor on combustion follows given that the molar mass of h2o is 18.02g/mol how many liters of propane are required at sfo to produce 75g of h2o from this reaction

find the number of moles of H2O using the molar mass of H2O 

moles of H2O = 75g/18.02 g/mol = 4.162 moles 

go between the H2O and the propane to find the mole of propane

4.162 moles H2O its a 1 : 4 ratio so divide 4.162 / 4 = 1.041mol of propane

use this equation to find the volume of gas required : V = nRT/P

n is the moles of gas (propane)

R is the universal gas constant (0.082057338)

T is the temperature of the gas (273K)

V = (1.041) x (0.08206 L-atm/mol-K) x (273K)/(1 atm)

V = 23.3 L of C3H8

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 .

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.
