Answer : The specific heat of tin is, 0.213 J/g.K
Explanation :
Formula used :
where,
q = amount of heat lost = -399.4 J
c = specific heat capacity of tin = ?
m = mass of tin = 25.0 g
= final temperature =
= initial temperature =
Now put all the given values in the above formula, we get:
Therefore, the specific heat of tin is, 0.213 J/g.K
Answer:
Chlorine gas.
Explanation:
Hello!
In this case, the undergoing chemical reaction is:
Thus, given the moles of reacting both sodium and chlorine, we compute the moles of sodium chloride yielded by each reactant by considering the 2:2 and 1:2 mole ratios:
Thus, since chlorine yields less moles of sodium chloride, we infer it is the limiting reactant.
Best regards!
