Answer:
<em>Uses energy: Amoeba and clock both use energy</em>
<em>Contains cells: true for the amoeba.</em>
<em>Lacks genetic material: true for a clock.</em>
<em>Reproduces: True for amoeba</em>
<em>Has internal organization: True for amoeba and clock both</em>
<em> </em>
Amoeba can be described as a single-celled organism and hence is a living thing. It will show characteristics of a living thing. Whereas, a clock can be described as a device to watch time. It is a non- living thing.
Acquired, because everyone has to learn how to speak English you can’t just be born and know how to speak.
Answer:
-1605.1 kJ
Explanation:
The enthalpy of formation is the enthalpy of the reaction that forms the substance only by its constituents, so, substances formed by one element, such as O2, in its ambient temperature phase, have an enthalpy of formation 0.
The enthalpy is a measure of how much heat the system contains, and so, the variation of it measures the heat lost (ΔH <0) or gained (ΔH >0), and for a reaction:
ΔHrxn = ∑ni*ΔHi products - ∑ni*Hi reactants
Where ni represents the coefficient of the substance, so by the data given:
ΔHrxn = [2*(-241.82) + (-393.5)] - [-74.6]
ΔHrxn = -802.54 kJ/ mol of CH4
Thus, the heat released is the enthalpy multiplied by the number of moles of CH4:
Q = -802.54*2
Q = -1605.1 kJ
