The correct answer is 5819.04 J
The energy (q) required to elevate an object of mass (m) and specific heat capacity (c) by a temperature (T) is given by q = mcΔT.
Here, m is 72 g, c is 0.449 J/Kg °C, ΔT = 260 - 80 = 180 °C
Now, putting the values we get,
q = 72 × 0.449 × 180
q = 5819.04 J of energy is absorbed by the skillet.
Answer:
Different elements emit differently colors of light because when electrons return to the lower energy levels, they emit energy in a different form of light
Explanation:
The molar mass constant can be used to convert mass to moles
Answer: C = 0.014M
Explanation:
From n= m/M= CV
m =43.5 M= 148, V=850ml
43.5/148= C× 0.85
C= 0.35M
Applying dilution formula
C1V1=C2V2
C1= 0.35, V1= 25ml, C2=?, V2= 600ml
0.35× 25 = C2× 600
C2= 0.014M
The steam is pure water and is a saturated vapor. the distillate product is 99 mol% methanol
