Answer:
The correct answer is 3.0 * 10^3 J.
Explanation:
To solve this problem, we must use the formula q = mcΔT, where q represents the heat energy measured in joules, m represents the mass measured in grams, c represents the specific heat measured in J/°C*g, and ΔT represents the change in temperature, measured in °C.
To solve this problem, we must first plug the given values into the equation.
q = mcΔT
q = (29.0 g)(4.184 J/°C*g)(25 °C)
Now, we must multiply the values together to get our final answer.
q = 3033.4 J
But, we must remember the rules of significant figures, which tell us that since the temperature only had 2 significant figures, the answer must have 2 significant figures as well.
Therefore, the answer is:
q = 3.0 * 10^3 J
Hope this helps!
