help please. What type of reaction is this: barium nitrate --> barium oxide + nitrogen dioxide + oxygen

Decomposition Reaction

Explanation:

Ba(NO₃)₂(s) ⇒ BaO(s) + N₂(g) + 3 O₂(g)

Barium nitrate decomposes into the chemical species that were used to create it.

58 km per hour : d

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.
