Answer:
Heat of the reaction per mole of NaOH = 46.02 kJ/mol
Explanation:
The reaction between HCl (strong acid) and NaOH(strong base) is a neutralization reaction which yields a salt NaCl and water
The heat (q) of a reaction is given as:
where m = mass of the system
c = specific heat
T1 and T2 are the initial and final temperatures
It is given that:
Volume of HCl = 500.0 ml
Volume of NaOH = 500.0 ml
Density of HCl and NaOH = 1.000 g/ml
Total mass of the solutions, m = 500.0 +500.0 = 1000.0 g
c = 4.184 J/g/c
T1 = 25.6 C
T2 = 26.70 C
Substituting appropriate values in equation (1) gives:
Now, the number of moles of NaOH is:
Heat of reaction/mole NaOH is:
Answer:
Logarithmic scale called pH
Explanation:
Electricity from renewable resources such as solar, geothermal, and wind generally does not contribute to climate change or local air pollution since no fuels are combusted.
Distance - how long it takes an object to go from one place to another.
