(i) Hydrogen chloride gas is prepared by treating Sodium chloride with concentrated sulphuric acid. The HCl gas is passed through a drying agent to remove moisture where concentrated sulphuric acid plays the role of dehydrating agent as well.
(ii) NaCl+H2
SO4 →NaHSO 4
+HCl(g)
Hope it helps :)
Answer:
Temperature, mass, and the type of material are factors that affect the thermal energy of an object.
Material with the higher specific heat will have more thermal energy than material with lower specific heat if they both have the same mass and temperature.
Answer: The enthalpy change during this reaction is 77505.56 J.
Explanation:
Given: 
, 
Mass = 254 g, Specific heat = 
Formula used to calculate the enthalpy change is as follows.
where,
q = enthalpy change
m = mass of substance
C = specific heat capacity
= initial temperature
= final temperature
Substitute the values into above formula as follows.
Thus, we can conclude that the enthalpy change during this reaction is 77505.56 J.
Answer:
no
Explanation:
that is a molecular formula
The correct answer would be C. The third option shows a correct balanced chemical reaction. In order to say a reaction is balanced, it should be that the atoms of each element in the reactant side and the product side would be equal in number.
