how much energy is released when 23 g of steam at 100 Celsius is condensed into liquid water?
H = mc∆T
H = 23g * 4.2J/g°C *(100°C - 0°C)
H = 9660 J
H = 9.66 KJ.
The energy released is 9.66 KJ.

how does the shape of the periodic table relate to electron configuration?
The shape of the periodic table is related to the electron configuration of elements by the arrangement of periods which can be used to guess the highest energy levels of the atom. Additionally, the group to which an atom belongs is the number of Valence electrons it has.
The periodic table is a systematic arrangement of elements in order of their atomic number with a set of 7 rows called periods and a set of 8 or 18 Columns called Groups.
In essence, the period of an element is a measure of the highest energy level shell of such an element.Additionally, the group of an element is as determined by the number of Valence electrons in the outermost shell of such an element.Ultimately, the s-, p-, d-, and f- group elements are visibly arranged and can be identified from the shape of the periodic table.

how are the light reactions and the calvin cycle connected?
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.

A hypothetical element has an atomic weight of 42.8452 amu. There are three main isotopes of this element with mass numbers of 41, 43 and 44. The 44 amu isotope has a 8% abundance. What is the percent abundance of the isotope with the mass number of 41?
1. 7.740%
2. 12.04%
3. 92.26%
4. 46.00%
5. 12.34\%
Answer:
Answer is 46.00%
Explanation:
absolute mass= A1F1 +A2F2
100
42.8452= 44×8% + 41×( 100--F2)
100
so you get
F2= 46.00%

Why do scientists create proxies?
Answer:
Proxies enable scientists to recreate climate conditions in different parts of history.
Explanation:
Proxies are characteristics of the weather in a certain period of time that have been preserved for different weather measurements like temperature, humidity, wind direction, and amounts of precipitation. The reason scientists create proxies because it "enables them to recreate climate conditions from different parts of time to have a better understanding on what weather was like during that time period."
