A base is a hydrogen acceptor according to the Brnsted-Lowry theory of bases and acids whereas an acidity is a proton (H+) donor. A Brnsted-Lowry acid transfers a proton, creating a conjugate base.
The Bronsted Wolff theory of bases and acids refers to what?In the Brnsted-Lowry theory, proton transport between chemical species is used to characterize acid-base interactions. Any organism that can give a proton is a Brnsted-Lowry acid, followed by H+start paragraph, H, \text, start subscripts, plus, and any species which can receive a proton is a base.
What distinguishes Lewis theory from the Brnsted-Lowry theory?Lewis' hypothesis is based on the movement of electrons, whereas the Brnsted-Lowry theory depends on the passage of protons. Lewis acids arematerial capable of taking in two electrons to create a new connection. They are sometimes known as electrophiles, or people who are looking for an extra electron pair.

Which best describes a system made up of ice, water and steam existing together?
a. absolute zero
b. triple point
c. ice point
d. steam point
Answer:
The correct answer is B. Triple Point.
Explanation:
The triple point is the temperature and pressure at which all three phases of a substance (in this case: ice, water, and steam) coexist in equilibrium. At the triple point, the temperature and pressure are precisely defined, and any change in either will cause the system to shift towards one of the three phases. This is in contrast to the other points, such as the ice point or steam point, which only pertain to a single phase.
A system made up of ice, water and steam existing together is described as the "triple point".
The triple point is a specific temperature and pressure at which the three phases of a substance (in this case, ice, water, and steam) can coexist in a stable state. At this point, the solid, liquid, and gaseous phases are in equilibrium, and a change in temperature or pressure will cause the substance to change phase.
Therefore, the answer is B) Triple point.

how many moles are present in 152 grams of FeSO4
Answer:
1.00 moles
Explanation:
Find the molar mass of FeSO4. Add the atomic masses (AMU) of each atom present from the periodic table..
1 Fe = 55.84
1 S = 32.1
4 O = 64
============
Total = 151.9 AMU for FeSO4
This is also the same number for the molar mass of FeSO4, but just expressed as grams/mole. It takes 151.9 grams of FeSO4 to have 1 mole of FeSO4 molecules.
The problem states that 152 grams are present. To obtain moles FeSO4, divide by the molar mass:
(152 grams FeSO4)/(151.9 grams/mole FeSO4) = 1.00 moles of FeSO4
[Note that the grams cancel and moles moves to the top in the division]
What would happen if a TLC plate was placed In a jar where the solvent level was above the level of the origin (sample spot)? What could you do if you inadvertently spotted your plate too low (aside from consulting your TA)?
If a TLC plate is placed in a jar where the solvent level is above the level of the origin (sample spot), the solvent will reach and dissolve the sample before it has a chance to form a spot. This can cause the sample to spread out and interfere with the accuracy of the results.
If you inadvertently spotted your TLC plate too low, one solution would be to let the solvent front reach the bottom of the plate, let the solvent evaporate, and then re-develop the plate with fresh solvent. This will help to avoid any interference from previous runs and ensure accurate results. Another solution would be to scrape off the low spots and re-spot the sample higher up on the plate. It's also a good practice to make a note of the error in your lab notes so that you can take it into account when interpreting your results
A TLC plate, or Thin Layer Chromatography plate, is a type of chromatography used in analytical chemistry to separate and identify components in a mixture.

Explain why iron from the blast furnace is harder than pure iron .
Iron produced in a blast furnace is harder than pure iron due to the presence of impurities and the way it is produced.
What happens in a blast furnace?In a blast furnace, iron ore is reduced to iron using coke as a reducing agent and a source of carbon. The high temperatures involved in this process result in the formation of a cast iron product that contains carbon and other impurities in the form of carbides and other compounds.
The presence of carbon and other impurities in the iron makes it harder and stronger than pure iron, which is relatively soft and ductile. The carbides formed during the reduction process act as tiny cutting edges, strengthening the iron and increasing its hardness.
This hardened iron is then melted and poured into molds to form pig iron, which can then be further processed to remove impurities and refine its properties. The end result is a stronger and harder iron product that is better suited for various applications, such as construction or manufacturing.

think critically the mendeleev and moseley periodic charts have gaps for undiscovered elements. why do you think the chart used by moseley was more accurate at predicting where new elements would be placed?
The chart used by moseley was more accurate at predicting where new elements would be placed, because Moseley's work chart based the atomic number which is definable property, measurable through experimentation not chemical properties or atomic mass as mendeleev do.
In his periodic table, Mendeleev left some notable gaps, such as the gaps just below aluminum and silicon, which covered elements as yet to be discovered. When these elements were later discovered, the properties of the new elements were found to match Mendeleev's predictions. The main difference between Mendeleev's and Moseley's arrangement of the elements on the periodic table is that Mendeleev arranged the elements in ascending order of atomic weight, whereas Moseley arranged them in ascending order of atomic number. Moseley diagrams were based on the use of atomic numbers rather than chemical properties of the elements. The similarity of products from the same period often caused problems when creating orders. Moseley's work made it possible to change atomic number from an arbitrary choice to a definable property that can be measured through experimentation.
