Answer: 0.548J/g°C
Explanation:
Q = s × m × DeltaT
Q = Heat (J)
S = Specific Heat Capacity
M = mass (g)
DeltaT = Change in temperature (°C)
0.158Kg x 1000 = 158g
2.510J = s x 158g x (61°C-32°C)
2.510J/(158g x 29°C) = s
S = 0.54779.... J/g°C
S = 0.548 J/g°C
Answer:
1. frequency = 7.39 * 10¹⁴ Hz
2. wavelength = 1.44 * 10⁸ nm
Explanation:
The speed, frequency and wavelength of waves are related by the formula;
speed = wavelength * frequency
1. wavelength of light = 406 nm = 4.06 * 10⁻⁷ m
speed of light is a constant = 3.0 * 10⁸ m/s
From the formula above, frequency = speed / wavelength
therefore, frequency = (3.0 * 10⁸ m/s) / 4.06 * 10⁻⁷ m
frequency = 7.39 * 10¹⁴ Hz
2. From the equation above, wavelength = speed/frequency
speed of radiation = 3.0 * 10⁸ m/s
frequency = 2.09 * 10⁹ Hz or 2.09 * 10⁹ s⁻¹
therefore, wavelength = (3.0 * 10⁸ m/s) / 2.09 * 10⁹ s⁻¹
wavelength = 1.44 * 10⁸ nm
<span>All 4 C-H bonds are identical.
Hybridisation or hybridization is the idea of blending atomic orbitals into new hybrid orbitals, with various energies, shapes, and so on, than the component atomic orbitals, appropriate for the matching of electrons to make chemical bonds in valence bond theory.

I don't think it's any of the above. Because there is two double carbon bonds and it belongs to an alkene, it should be an ethene molecule.
