Yes because you have to use fuel to drive that's my guess
Answer: The energy of a Br–F bond is 110 kJ/mol
Explanation:
The balanced chemical reaction is,
The expression for enthalpy change is,
where,
n = number of moles
Now put all the given values in this expression, we get
Thus the energy, in kJ/mol, of a Br–F bond is 110
A prediction is not based upon evidence or reliable tests. A prediction is a guess as to what will happen in the future. Forecasts for example are nothing more than prediction, as even with "meteorological evidence", nothing is ever truly sure when in regard to wheather.
So "A"
Answer:
C = 0.7385J/g°C
Explanation:
Heat energy (Q) = 54J
Mass (m) = 2.47g
Initial temperature (T1) = 17.10°C
Final temperature (T2) = 46.70°C
Specific heat capacity of substance (c) = ?
Heat energy of a substance (Q) = Mc∇T
Q = heat energy
M = mass of the substance
C = specific heat capacity of the substance
∇T = change in temperature of substance = T2 - T1
Q = mc∇T
Q = mc (T2 - T1)
54 = 2.47 * c * (46.70 - 17.10)
54 = 2.47 * 29.6 * c
54 = 73.112c
C = 54 / 73.112
C = 0.7385
Specific heat capacity of the substance is 0.7385J/g°C
B.
The specific heat capacity of the above substance does not match any metal in the periodic table, however the closest to it was potassium with a value of 0.7536J/g°C and silicone with value of 0.711756J/g°C
