Answer:−329.4 calorie
Explanation:Heat released by metal = q=m_mc_m(T_2-T1)q=m

q=50×0.108(17−78)=−329.4 calorie
Here minus sign indicate that heat is released
Answer:
Characteristics of Group
Explanation:
The elements of a group show similar chemical properties but there is a gradual variation in the physical properties of the elements in a group.
Answer:
A calorimeter is an object used for calorimetry, or the process of measuring the heat of chemical reactions or physical changes as well as heat capacity. Differential scanning calorimeters, isothermal micro calorimeters, titration calorimeters and accelerated rate calorimeters are among the most common types.
Explanation:
Answer:
The titrant is a strong acid while the analyte is a strong base
Explanation:
A titration curve is a graphical representation of the pH of a solution during a titration. The figure in the question shows a particular example of a strong acid-strong base titration curve. This is a titration in which the acid is added to the base thus the pH progresses from low to high.
Hence, the titrant is the strong acid delivered from the burette while the analyte is the base as shown by the titration curve in which acid is delivered to the base.
