Explanation: 2.016 H (2*1.008) + 15.999 O (1*15.999)
Answer:
The level of toxins in solutions
Answer: Temperature final = 103 °C
Explanation: To solve for final temperature we use the equation of heat:
Q= mc∆T
Next derive the equation to find final temperature
Q = mc(T final - T initial)
Q / mc = T final - T initial
Transpose T initial and change the sign so that T final will be left.
T final = Q / mc + T initial
Substitute the values:
T final = 305 J / 28.8 g x 0.128 J/(g°C)
= 305 J / 3.6864 J/°C
= 82.7 + 20.0°C
= 103 °C final temperature.
