Answer:
instantaneous rate would be the term.
Answer:
This happens because there was an electric charge.
Answer:
The enthalpy change during the reaction is -199. kJ/mol.
Explanation:
Mass of solution = m
Volume of solution = 100.0 mL
Density of solution = d = 1.00 g/mL
First we have to calculate the heat gained by the solution in coffee-cup calorimeter.
where,
m = mass of solution = 100 g
q = heat gained = ?
c = specific heat =
= final temperature =
= initial temperature =
Now put all the given values in the above formula, we get:
Now we have to calculate the enthalpy change during the reaction.
where,
= enthalpy change = ?
q = heat gained = 2.242 kJ
n = number of moles fructose =
Therefore, the enthalpy change during the reaction is -199. kJ/mol.
Answer:
When the concentration is higher, more hydrogen ions are near the Zn atoms at any given time. This allows for more Zn atoms to be ionized and dissolved into the solution per second.
Explanation:
Answer:
I think it's b.
Explanation:
Because solubility increased by temperature.
