Answer:
Q = 44.9 j
Explanation:
Mass of iron = 5.0 g
Change in temperature = 20 °C
Specific heat of iron = 0.449 j/g.°C
Heat transferred = ?
Formula:
<em>Q = m.c. ΔT
</em>
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
Solution:
<em>Q = m.c. ΔT
</em>
Q = 5 g × 0.449 j/g.°C × 20 °C
Q = 44.9 j
A type of atom can be of any type. Elements are pure chemicals that cannot be converted into more basic compounds by conventional chemical processes.
A chemical element is a substance that cannot be disassembled chemically or physically into simpler substances. Chemical elements are the basic building blocks of matter because they are pure substances made up of atoms with the same atomic number (number of protons) in their nuclei. A chemical element is essentially a pure substance that cannot be disintegrated, degraded, or changed into other compounds through physical or chemical methods.

Answer: The amount of coffee is the same
Explanation: This was the correct answer for me.
The answer is clearly the option <span>A, because in the Urey/Miller experiment, they simulated Earth's early atmosphere and they simulated the lightning as electrodes, to see if single compounds or amino acids would form. Hope this is useful</span>
Free energy is the answer i hope this helped
