Answer:
Under the earth's surface, rocks melt, metamorphize, and crystalize.
Explanation:
Metamorphic and Igneous rocks are basically dependant on the heat/pressure of the environment under the surface :) Melting, metamorphosing and crystallization all occur under earth's surface.
Yes that should be correct
To calculate the amount of heat entering or leaving a system, the equation <span>Q=mcΔT</span> is used.
Explanation:
m = mass (in grams)
c = specific heat capacity (J/g°C)
ΔT = change in temperature (°C)
Here, we will use the specific heat capacity for liquid water which is 4.19 J/g°C.
The mass given is 25.0 grams.
As for the change in temperature, I will assume that it start off at room temperature, 25°C.
<span>25°C−0°C=25°C</span>
<span>Q=mcΔT</span>
<span>Q=25grams⋅4.19<span>J<span>g°C</span></span>⋅25°C</span>
<span>Q=2618.75J</span>
Take into account significant figures and the answer should be
<span>2.6⋅<span>103</span><span>J</span></span>
Oxygen = 16
Iron = 55.8
16 x 27.6% = 4.4 /4 = 1.1
55.8 x 72.4% = 40.4 /4 = 10.1
1 oxygen and 10 iron, so Fe10 O
