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 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.

what is the maximum time food can remain in the temperature danger zone
Answer:2 hours
This range of temperatures is often called the "Danger Zone." Never leave food out of refrigeration over 2 hours. If the temperature is above 90 °F, food should not be left out more than 1 hour. Keep hot food hot—at or above 140 °F.

What two factors must be held constant for density to be a constant ratio?
The two factors which must be held constant for density to be a constant ratio are: Mass and Volume
As we know, the density of a material is simply defined as the ratio of mass to volume.
In essence, Density = Mass/VolumeConsequently, To obtain a constant ratio for density, the mass and volume of the material in discuss must be kept constant.

what is the maximum theoretical number of water molecules with which, in theory, one urea molecule can hydrogen bond?
Answer:
The maximum number of molecules that one water molecule can hold through hydrogen bonding is 4 because the two hydrogen atoms of water can form two hydrogen bonds and the two lone pairs on oxygen can also form two hydrogen bonds. hope it helps
Two scientists work together on an experiment, but they have different hypotheses. When scientists look at the experimental results, they interpret the data in different ways and come to different conclusions. Which of the following does this situation best illustrate?
Answer:
The correct answer is option D, confirmation bias.
The correct answer is option D, confirmation bias.Confirmation bias is the tendency to interpret data in a way that confirms the already designed hypotheses.
The correct answer is option D, confirmation bias.Confirmation bias is the tendency to interpret data in a way that confirms the already designed hypotheses.As the two scientists interpret the data (or experimental results) in different ways to adhere to the different hypotheses. this is also called indicative of cognitive bias. This is also called inductive reasoning where the premise is viewed as evidence for the validity of the conclusion.

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%

1. Why do plant cells have a cell wall in addition to a cell membrane?
2. Think about the function of chloroplasts. Would you expect to find
more chloroplast in the cells of leaves or the roots of a plant?
3.What two cell structures do protists have that bacteria do not?
4. Do all microbes cause disease? Explain
Answer:
Plant cells have a cell wall and chloroplasts; animal cells do not have either of these structures.
Explanation:
A major difference between a plant cell and an animal cell is presence of chloroplasts in plant cells. Another key difference between plant and animal cells is the presence of a cell wall in plant cells. Both structures are absent in an animal cells.
The cell wall surrounds the plasma membrane of plant cells. This helps to provide the required tensile strength and protection against mechanical and osmotic stress.
Cell walls also help plants to maintain shape and rigidity.
Answer:
1) Plant cells have a cell wall to strengthen the cell
2) Chloroplasts are the site of photosynthesis (turning light energy in sugar) so there would eb a lot more in the leaves that get sunlight than the roots which are underground and receive no sunlight
3) Mitochondria and nucleus
4) No. Some microorganisms are useful to humans, such as the bacteria that create yoghurt, or fungi such as penicillin which are antibiotics, which help us fight bacterial infections
