Answer:
0.296 J/g°C
Explanation:
Step 1:
Data obtained from the question.
Mass (M) =35g
Heat Absorbed (Q) = 1606 J
Initial temperature (T1) = 10°C
Final temperature (T2) = 165°C
Change in temperature (ΔT) = T2 – T1 = 165°C – 10°C = 155°C
Specific heat capacity (C) =..?
Step 2:
Determination of the specific heat capacity of iron.
Q = MCΔT
C = Q/MΔT
C = 1606 / (35 x 155)
C = 0.296 J/g°C
Therefore, the specific heat capacity of iron is 0.296 J/g°C
Answer:
Option D. T
Explanation:
Enthalpy change (ΔH) is simply the difference between the heat content of the product (Hp) and the heat content of the reactant (Hr). Mathematically, it is expressed as:
Enthalpy change (ΔH) = Heat of product (Hp) – heat of reactant (Hr)
ΔH = Hp – Hr
From the diagram given above, the difference between the heat content of product and the heat content of reactant is T.
Therefore, the enthalpy change of the reaction is T.

Answer:
A) it is converted to an SI unit of measurement
Explanation:
The SI, System International units are the fundamental units used to measure the scientific quantities.
Example of SI units are Kilogram (km) for distance, liter (l) for liquid, centimeter (cm), and meter (m) for size of the object or short distance etcetera.
SI units help to differentiate quantities from each other and without using SI unit, no one can identify the category of the quantity whether it is distance, size or volume.
Hence, the correct answer is "A) it is converted to an SI unit of measurement".
