Solid iron reacts with sulfuric acid (H2SO2) to produce iron (II) sulfate and hydrogen gas. If 850 mL of hydrogen gas are collected at STP, how many grams
of iron (II) sulfate are also produced?

idk i’m struggling too

c- cold periods in earth's history during which glaciers covered much of the surface.

explanation:

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.
