2. Consider the table of boiling points and structural isomers. Note that butane has two possible isomers but that decane has 75 possible isomers. Why does the number of possible isomers go up with an increasing number of carbon atoms?
Answer:
because the number of constitutional confirmation , and geometric isomers goes up with each carbon atom added there are many more possible configurations and connectivities possible with decane , a 10 carbon chain , than with butane, a 4 carbon chain
"The number of possible isomers go up with an increasing number of carbon atoms because as the number of carbon atoms increases the tendency to form branching with other carbon atom increases as well."
What is isomer?
Isomers are molecules or polyatomic ions that have the same molecular formulas that is, the identical number of atoms of each element but different atomic configurations in space. Isomerism refers to the existence or potential of isomers. Isomers don't have to have the same chemical or physical properties.

How does fog rising off water compare to plant growth?
The humidity in the air affects the evapotranspiration rate from the leaf surfaces. ... The use of fog and mist at this time can reduce the air temperature and increase the humidity within the plant canopy without saturating the plant medium. With more oxygen in the root zone, faster rooting occurs.
This is an unbalanced equation representing a chemical reaction HgO->Hg+O2 (two is supposed to be small and on the bottom right part of the O) Which equation is the correctly balanced chemical equation for this reaction? A. HgO->Hg+20 (and a tiny 2 next to the 20) B. 2Hgo->Hg+0 (and a tiny 2 next to the 0) C. 2HgO->2Hg+0 (and a tiny 2 next to the 0) D. 2Hgo->Hg+20 (and a tiny 2 next to the 20)
Answer: C. [tex]2HgO\rightarrow 2Hg+O_2[/tex]
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
The skeletal chemical equation will be:
[tex]HgO\rightarrow Hg+O_2[/tex]
The balanced chemical equation will be:
[tex]2HgO\rightarrow 2Hg+O_2[/tex]
The correctly balanced chemical equation for the reaction [tex]HgO - > Hg + O_{2}[/tex] is: C. [tex]2HgO - > 2Hg + O_{2}[/tex]
The law of conservation of mass states that mass can neither be created nor destroyed; it can only be transferred from one location to another. As a result, the mass of the products is required to be the same as the mass of the reactants.
On both the reactant and product sides of the reaction, the identical amount of atoms of each element is required. Therefore, the equations used in chemistry are balanced.

Which of the following is an example of mutualism?
Answer:The relationship which is between bacteria and ungulates with the intestine is or good example of mutualism. Mutualism plays an important role in ecology. We can say that if we measure the exact fitness what we get as a benefit is a mutualistic relationship.example of a mutualistic relationship is that of the oxpecker (a kind of bird) and the rhinoceros or zebra. Oxpeckers land on rhinos or zebras and eat ticks and other parasites that live on their skin. The oxpeckers get food and the beasts get pest control.

What is the manipulated variable, responding variable, and controlled Variable
observe different electrolytes in a wet cell that will light a
bulb most brightly.
Answer:
Manipulated/independent variable- DIFFERENT ELECTROLYTES
Responding/dependent variable- BRIGHTNESS OF BULB
Controlled variable- WET CELL
Explanation:
The independent variable, also known as manipulated variable is the variable that the experimenter changes or manipulates in an experiment. In this case where different electrolytes are observed to see which will light a bulb most brightly, the manipulated variable is the DIFFERENT ELECTROLYTES.
Dependent or responding variable is the variable of an experiment that responds to the changes made to the independent variable. It is the variable that is being measured in an experiment. In this case, the BRIGHTNESS OF BULB is dependent on the electrolyte used, hence, it is the responding variable.
Controlled variable or constant is the variable that the experimenter keeps the same throughout the experiment. In this case, the WET CELL is kept constant for all the electrolytes used i.e. it is not changed, hence, the WET CELL is the controlled variable.

An effective treatment for some cancerous tumors involves irradiation with "fast" neutrons. The neutrons from one treatment source have an average velocity of 3.5×107 m/s. If the velocities of individual neutrons are known to within 2.0% of this value, what is the uncertainty in the position of one of them?
Answer:
4.54 * 10^-14 m
Explanation:
From Heisenberg's uncertainty principle, we can write;
Δp.Δx ≥ h/4π
Given that;
Δp =Δmv
So;
Δmv.Δx ≥h/4π
Δmv =2/100(3.5×10^7 m/s * 1.66 * 10^-27)
Δmv =1.162 * 10^-21 Kgms-1
Δx ≥6.63 * 10^-34 /4 * 3.142 * 1.162 * 10^-21
Δx ≥4.54 * 10^-14 m

How many moles of water are produced from the reaction of oxygen with four moles of propane (C3H8)? C3H8 + 5O2 --> 3CO2 + 4H2O
Answer:
Explanation:
The reaction is:
C₃H₈ + 5O₂ → 3CO₂ + 4H₂O
We see, that the equation is ballanced.
As we have data from only one reactant, we assume the other is in excess.
Ratio is 1:4 (stoichiometry). We solve this, by a rule of three:
1 mol of propane can produce 4 moles of water
Then, 4 moles of propane, may produce
( 4 . 4 ) /1 = 16 moles of water can be made.
Remember, we always have to work with the limiting reactant.

When developing a product such as cookware specific heat well as health cost and ease of use our important factors to consider one of the materials tested which is the best suited for cookware and why explain based on safety/health cost specific heat and ease of use
Answer:
In short, the thermal conductivity of a material is how readily that material absorbs and transmits (releases) energy. When the fire or heating element of a range comes in contact to a pan, the energy from the heat source is transmitted to the pan. This increases the internal kinetic energy of the pan (commonly called "heating up"). The heated material then transmits the energy to nearby materials that are at a lower average molecular kinetic energy level (at a lower temperature than the material). The higher the thermal conductivity of the material, the faster it will heat up and also, the faster the heated area will spread to unheated areas of the same piece of material.
For example, if we placed a large sheet of stainless steel (fairly low thermal conductivity as cooking materials go) on a burner and turned on the burner, the area directly under the burner would get hot while the rest of the sheet slowly heats up. The burner imparts heat quickly only to the region of steel directly over it. The rest of the pan heats up from the conduction of the heat from that spot. When the outer edges of the sheet have reached a hot temperature, the spot directly over the burner would be extremely hot. The figure below shows an example of the temperature of the sheet of steel over a gas burner. The hottest parts are shown in white, hot is red and cool is blue.
