Answer:
1. The same pattern of phases repeats monthly
2. Waxing moon phases are visible between the new and full moon
6. A full moon appears toward the middle of a lunar month
Explanation:
Moon has eight phases which is used by the ancient people for the identification of date of the month. Phases of moon tells us about the starting, middle and end of the month. At the starting of the month, waxing crescent appears while at the middle of the month, the moon gains its full shape. Phases which occurs between new and full moon is known as waxing.
Answer is: solution A has 2,57 time greater pH value than solution B.<span>
</span>Concentration of [H⁺] in solution A is than 370x.
pH = -log[H⁺].
pH(solution A) = -log(370x).
pH(solution b) = -log(x).
pH(solution A) / pH(solution B) = -log(370x) / -log(x).
pH(solution A) / pH(solution B) = 2,57.
The inaccurate statement is C. Oxidation and reduction don't necessarily happen together, and oxidation doesn't happen first.
Answer:
If you are thinking of the thermodynamic definitions Internal energy change is defined as the heat gained by a system less the work done by the system
E = Q-W. This combination is a state function meaning it depends on the initial and final states of a system and is path independent while work and heat change are path dependent.
Enthalpy change is defined as H = E+ PV A change in Enthalpy is also a state function. The most useful factor of enthalpy is that at constant pressure The heat of reaction Q is a measure of enthalpy and is also a state function.
hope this helps !!
