Calcium carbonate is decomposed by HCl as follows: CaCO3 + 2HCl→CaCl2 + H2O+CO2

a. Calculate the mass of water produced by the reaction of 4 mol. Of CaCO3
with 4 mol. Of HCl.

b. Define limiting reagent.

c. If 2 mol. Of CaCO3
produces 40 L of CO2 at NTP upon reaction with excess
HCl, what is the % age yield of the reaction.

d. If 250 g. of CaCO3 upon reaction with excess HCl gives 222 g. of CaCl2,
what is the % age purity of CaCo3?

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.
