According to Arrhenius Theory of acids and bases, an Arrhenius base produces OH-.
Among the four options, (3) LiOH is the correct one because it can separate into Li+ and OH- when being put in water.
Hope this helps~
Answer:
31.9178 °C is the final temperature of the water
Explanation:
Mass of benzene burned = 6.200 g
Moles of benzene burned =
According to reaction , 2 moles of benzene gives 6542 kJ of energy on combustion.
Then 0.0794 mol of benzene on combustion will give:
Mass of water in which Q heat is added = m = 5691 g
Initial temperature =
Final temperature =
Specific heat of water = c = 4.18 J/g°C
Change in temperature of water =
31.9178 °C is the final temperature of the water

Explanation:
It works nicely to let a spreadsheet do the calculations described in your problem statement.
You don't actually have to multiply by 100 to make the number a percent. Spreadsheets have the capability to show a value as a percentage just by changing the format.
