Besides its use in making black-and-white film, silver nitrate (agno3) is used similarly in forensic science. the nacl left behind in the sweat of a fingerprint is treated with agno3 solution to form agcl. the precipitate is developed to show the black-and-white fingerprint pattern. given δhlattice of agno3 = 822 kj/mol and δhhydr = −799 kj/mol, calculate its δhsoln.

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.

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
