Find the proportion, and multiply it by 100 to get the percentage.
The proportion is 2.9/3.1=0.935
The percentage is 0.935*100=93.5
Answer:
heat travels easier through plants so plants dont heat up as much
thus is because metal is much more dense than the grass
Answer:
The final temperature of the solution is 46.93°C
Explanation:
we have to calculate the heat produced.
where,
= enthalpy change = 81.5 kJ/mol
q = heat released = ?
m = mass of CaCl_2 = 15.0 g
Molar mass of CaCl_2 = 110.98 g/mol
Now put all the given values in the above formula, we get:
calculate the final temperature of solution in the calorimeter.
where,
q = heat produced = 11.0 kJ = 11000 J
m = mass of solution = 15.0 + 105 = 120.0 g
c = specific heat capacity of water = 4.18J/g°C
= initial temperature = 25.0°C
= final temperature = ?
Now put all the given values in the above formula, we get:
The final temperature of the solution is 46.93°C
