No, because plastic cups can be dissolved by organic compounds. Moreover, they are easily melted so a highly exothermic reaction can not be studied using them.
an erosive process or erosion
erosion is when a rock is changed through the weather
The answer is 3 moles as per given balanced equation one mole Zn produces 1mole Hydrogen
when reacted with excess acid.
<span>So 3 moles Zn will give 3moles Hydroge</span>
