Determine the empirical formula of an organic hydrocarbon compound that contains 80% by mass of carbon and 20% by mass of hydrogen. if the mr of the compound is 30, what is the molecular formula?

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.

the answer is a! (2.9 x 10^-18 j) hope i could someone. : )

nuclear fission produces elements that are heavier than helium.

the elements that are used in nuclear fission and their products are much heavier than helium.
