The balanced chemical equation represent the reaction between zinc (Zn) and hydrochloric acid (HCI). Zn + 2HCl + H2 + ZnCl2
At STP, how many liters of hydrogen gas (Hz) will be produced if 31.2 g of zinc is allowed to react with excess
hydrochloric acid?
A 2.82L
B 4.30 L
C 9.66 L
D 10.7 L

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.
