Question
I only need C answered:
Consider the equation for the dissolution of calcium in acid. Ca(s) + 2 H+(aq) rightarrow Ca2+(aq) + H2(g) Calculate the minimum volume of 1.00 M HCI required to react completely with 5.00 g of Ca. Suppose, instead, that 5.00 g Ca is added to 50.0mL of 1.00M HCI. Determine the limiting reactant in this case and the number of moles calcium actually consumed. Delta Hrxn values can be used in stoichiometric calculations as it is it is the heat involved per mole of calcium. Given the conditions stated in part(b), how many joules of heat would be liberated?(Do not perform this experiment ,but merely calculate the result.) The specific heat of water is 4.18 J K-1g-1. The density of water is 1.00 g cm-3.Explanation / Answer
you need some additional information such as inital and final temprature of the solution or delta H for conversion of H+ into H2(g)
If you have change in temp then
Q= msdeltaT
m is 55 gm
s= 4.18 adn put delta T accordingly
