Answer:
S(metal) = 0.66J/g°C
Explanation:
We can find specific heat of a material, S, using the equation:
q = m*S*ΔT
<em>Where q is change in heat, m is the mass of the substance, S specific heat and ΔT change in temperature.</em>
The heat given by the metal is equal to the heat that water absorbs, that is:
m(Metal)*S(metal)*ΔT(Metal) = m(Water)*S(water)*ΔT(water)
<em>Where:</em>
m(Metal) = 76.0g
S(metal) = ?
ΔT(Metal) = 96.0°C-31.0°C = 65.0°C
m(Water) = 120.0g
S(water) = 4.184J/g°C
ΔT(water) = 31.0°C-24.5°C = 6.5°C
Replacing:
76.0g*S(metal)*65.0°C = 120.0g*4.184J/g°C*6.5°C
S(metal) = 0.66J/g°C

The law of conservation applies because the energy is not been created or destroyed. The energy that the metal gives is absorbed by the water.
Phosphorous has three lone electrons that need pairing. Similar to how carbon has 4 lone electrons, and forms CH4
Answer:
It is higher.
Explanation:
The amplitude of a wave that carries more energy is usually higher.
The energy carried by a wave is related to the amplitude in such a manner that it is proportional to the square amplitude.
Amplitude is the maximum vertical displacement of a wave moving along its path.
- Energy of wave and its amplitude are directly proportional to one another.
- If the energy of wave is doubled, the amplitude is quadrupled.
- So, the higher the energy of a wave, the more its amplitude.
