Answer:
The invention of the wheel had an important impact on farming.
Answer:
The conditions for biochemical, chemical and both standard states are shown below
Explanation:
Chemical standard state:
Temperature is 25°
Intial concntration of reactants and products is 1M
g. Presurre is 1 atm.
PH7
Biochemical standard state:
Temperature is 25°
PH7
Constant value of Mg2+
Both:
Intial concntration of reactants and products is 1M
g. Presurre is 1 atm.
Temperature is 25°
PH7
I believe the statement that is true would be B.
Answer:
Hence among the options a and c, option d is that the correct answer because it has rock bottom energy ( as n value increases, energy decreases as energy levels come closer).
Explanation:
The relation between energy and wavelength is:
From this equation, it's clear that wavelength and energy are inversely proportional to every other. The Lower the energy of a specific transition, the longest will the wavelength be of that specific transition.
Among the given options, options b and d are often ruled out, since those transitions produce to release of a photon because it is coming down from an excited state.
Answer:
144 u
Explanation:
The average atomic mass of carbon is approximately 12 u.
Multiply 12 x 12:
12 x 12 = 144
