I would say 2 because co2 goes out and o goes in
Heat and light- The sun because it gives us daylight and it produces heat. These arent made by a chemical reaction when it comes to the sun.
Answer: 5.185
Explanation: The sum for 1.55 + 0.235 + 3.4 = 5.185
A calorimeter contains 500 g of water at 25°C.....
the temperature of the water inside the calorimeter is 39.4°C.....
The specific heat of water is 4.18 J/g-°C.
energy needed to heat the water = specific heat * mass * temp difference
= 4.18 J/g-°C * 500 g * (39.4°C - 25°C)
= 4.18*500*14.4
= 30096J
or approx. 30kJ
