Calculate the amount of heat, in Joules, needed to raise 34.0g of water from 55.0°C to 76.0*C. The specific heat of water is 4.18 J/gºC.

2984.52J

Explanation:

Using the formula: Q = m × c × ∆T

Where;

Q = amount of heat (in Joules)

m = mass (in grams)

c = specific heat capacity (J/g°C)

∆T = change in temperature (°C)

Based on the information provided in the question;

m = 34.0g

c = 4.18 J/gºC.

Initial temperature = 55.0°C

Final temperature = 76.0°C

Hence, Q = m × c × ∆T

Q = 34 × 4.18 × (76 - 55)

Q = 142.12 × 21

Q = 2984.52J

Therefore, 2984.52J is the amount of heat, in Joules, needed to raise 34.0g of the water.

you did not give any options thus this is the best answer i can give to you with this little information you have given

> they are both natural and not man made

> they can be tracked and predicted by the right tools

catya your not at all which answer i've seen you do this on another question!
