Question
Can you help me solve 2,3 and 4?

Transcribed Image Text:Reaction 1
Mass of NaOH
Initial temperature
Final temperature
0.56 g
26.5 celsius
31 celsius
1. Calculate the temperature change (AT) for the reaction.
2. Assuming the mass(m) of the reaction mixture = 0.5 g, and the specific heat (c) = 1.000
cal/g C, calculate the heat (q) released by the reaction using the formula q = mc(AT)
3. Convert the grams of NaOH used to moles using the molar mass of NaOH (40 g/mol).
4. Divide q/mol NaOH to get the heat of the reaction 1 (AH₁).
