if an exothermic reaction takes place in an insulated container at the end of the reaction the temperature of the content of the container will

Remain the same.

Explanation:

The reaction of the temperature of the content of the container will remain the same because no heat energy is transfer from the container to the external environment due to insulating material of the container. Insulators are poor conductor of heat and electricity so the container is unable to absorb the heat energy produced during a chemical reaction and all energy of the product remain the same.

i think it is true since you can test the answer and can use observations to complete it.

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.
