Calculate the heat of precipitation when 50cm3 of 0.25 moldm-3 silver nitrate solution is added to 50cm3 of 0.25 moldm-3 sodium chloride solution. The temperature increased

6◦C during the reaction. (c= 4.2 Jg-1

◦C ; density of solution = 1gcm-3

)​

< > according to newton's third law of motion, forces always act in equal but opposite pairs. another way of saying this is for every action, there is an equal but opposite reaction.< >

since electrons are negative the answer is neagtaive

bcde is the incorrect answer it is a

the formula mass of a molecule or a compound is the sum of the atomic weights of the atoms in its empirical formula

(that's what i know about formula mass)
