what is the maximum wavelength of photon that will eject a ground state electron from a hydrogen atom?
Answers
Answer:
9.13 x 10^-8 m
Explanation:
The maximum wavelength of photon that will eject a ground state electron from a hydrogen atom is 9.18 * 10^-8.
What is wavelength?
Wavelength is defined as the distance between identical points in the adjacent cycle of a waveform signal propagated in space or along the wires.
Wavelength is calculated as wave speed and frequency.
Wavelength = speed/frequency
SI unit of wavelength is meter.
A ground state atom is an atom in which total energy of the electron can not be lowered by transferring one or more electrons to different orbitals.
Thus, the maximum wavelength of photon that will eject a ground state electron from a hydrogen atom is 9.18 * 10^-8.

33: 12.50400
34: 210.42700
35: 63.88200 cm
36: -970.8772
Explanation:
4.550 x 300.4 = 1366.82
2.45002 + 4.0006 = 6.45062
26.004 - 13.5 = 12.50400
2.667 + (5.6 x 37.1) = 210.42700
2.34 x 4.55 x 6.0 = 63.88200
4.60 x 5.16 x 1.05 + 6.2 - 1002 = -970.8772

Which choice is an element? carbon dioxide water carbon air
Answers
Answer:
carbon
Explanation:
Considering the definition of elements ans compounds, carbon is an element.
Elements are simple substances that cannot be broken down by common chemical methods. The atoms in an element are the same as each other, yet they are different from those in other elements. In addition, the elements are represented by a symbol and can be found in the periodic table.
On the other hand, compounds are substances that are the result of the chemical union of two or more elements. This combination makes it impossible to identify each element by its individual and original properties. Compounds can be separated by chemical action.
In summary, the element is a pure chemical substance formed from an atom, which is characterized in that it cannot be divided or transformed by a chemical reaction. Whereas a compound is a pure chemical substance made up of a particular set of molecules or ions that are chemically bound together.
So, being:
carbon dioxide: composed of carbon and oxygen water: composed of two atoms of hydrogen and one of oxygenair: composed mainly of oxygen and nitrogenthen, carbon is an element.

For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.
Here calcium is having an oxidation state of +2 called as Ca^{2+}Ca2+ cation and NO_3^{-}NO3− is a polyatomic anion with oxidation state of -1.. Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral Ca(NO_3)_2Ca(NO3)2

how are the light reactions and the calvin cycle connected?
Answers
Answer:
The light reactions provide the Calvin cycle with oxygen for carbon fixation, and the Calvin cycle provides the light reactions with sugars to produce ATP. The light reactions provide ATP and NADPH to the carbon fixation step of the Calvin cycle, and the Calvin cycle provides water and electrons to the light reactions.
Explanation:
The energy that drives the Calvin cycle comes from ATP and NADPH produced by the light reactions, that is, the energy capture reactions in the first stage of photosynthesis.
The Calvin cycle is a process that results from photosynthesis made by plants, through which Carbon dioxide is absorbed and transformed into organic material or biomass.
In the light phase, light energy is stored in organic molecules that provide energy to carry out the process (ATP) and have the ability to donate electrons (reducing power) to another molecule such as NADPH.These molecules formed in the light reactions participate in the reactions that make up this cycle during which carbon dioxide (CO2) taken from the atmosphere is fixed, incorporating it into the body in the form of glucose thanks to the action of the enzyme RuBisCo.Therefore, we can conclude that the molecules constituted in the light reactions (ATP and NADPH) participate in the reduction of carbon dioxide (CO2) through the series of reactions of the Calvin Cycle.
