Part B A certain second-order reaction (B-products) has a rate constant of 1.30210-3 Ml. s-at 27°C
and an initial half-life of 300 s. What is the concentration of the reactant B after one half-life?

the law of conservation of mass states that in a chemical reaction, the total mass of reactants is equal to the total mass of products. because atoms are only rearranged in a chemical reaction, there must be the same number of sodium atoms and chlorine atoms in both the reactants and products

mark him as !

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."

im not exactly sure but i think its b!
