Determine the oxidation number (oxidation state) of each element in the compound CuCO 3 . Cu : C : O : Determine the oxidation number of each element in CH 4 . C : H : Determine the oxidation number of each element in IF . I : F : Determine the oxidation number of each element in CH 2 Cl 2 . C : H : Cl : Determine the oxidation number of each element in SO 2 . S : O : Determine the oxidation number of each element in ( NH 4 ) 2 CrO 4 . N : H : Cr : O :

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.

its pwirhfpiwe

explanation:

because dgjpwojefopjwp

if the temperature drops and becomes cool

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but
