What is the benefit of the electrostatic layers that form around the dispersed particles in colloids

If you have 5.25 grams of methane (ch4), how many grams of co2 will you produce ?

Describe the interaction that occurs between two objects with the same electrical charge.

Consider the reaction: 2al(s) + fe2o3(s) → al2o3(s) + 2fe(s) the δhf for fe2o3(s) = -824.3 kj/mole. the δhf for al2o3(s) = -1675.7 kj/mole. finish the equation. δhrxn = [(1)( kj/mole) + (2)( kj/mole)] - [(1)( kj/mole) + (2) ( kj/mole)]
