suppose polyethylene molecules in solution can exist either as a random coil or fully stretched out, with the latter conformation 2.4 KJ/mol hieher in energy. what is the ratio of the two conformation at 20 centigrade

According to coulomb's law, how would the electrical force between particles change if the product of their electrical charge increased?

Use examples from the article to explain one positive and one negative effect that chemistry has had on society.

Cryolite, na3alf6(s), an ore used in the production of aluminum, can be synthesized using aluminum oxide. start this question by first balance the chemical equation.1.) balance the equation: - alo3(s)+naoh(l)+hf(> na3alf6+h2o(g). 2.) if 17.5 kilograms of al2o3(s), 51.4 kilograms of naoh(l), and 51.4 kilograms of hf(g) react completely, how many kilograms of cryolite will be produced? 3.)which reactants will be in excess, (al2o3, naoh, or hf) 4.)what is the total mass of the excess reactants left over after the reaction is complete in kg?
