Ireally need some and explaining with the heat of combustion lab. 1. you may recall that the products of the complete combustion of a hydrocarbon are water vapor and carbon dioxide gas. write the balanced equation showing the combustion of methane. do not forget to include the states of matter of the reactants and the products. hint: methane is a gas at standard temperature and pressure.

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.

< > 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.< >
