d. react with water forming solvated ions.
9) The hydrogen bonding interaction between particles of allyl alcohol and water

b. and the hydrogen atom of allyl alcohol that is covalently bonded to the oxygen atom.
c. and the hydrogen atom of allyl alcohol that is covalently bonded to the carbon atom.
d. Actually, hydrogen bonding is NOT the intermolecular force between allyl alcohol and
water
10) The hydrogen bonding interaction between particles of allyl alcohol and water
occurs between the oxygen atom of water
a. and the oxygen atom of allyl alcohol.
b. and the hydrogen atom of allyl alcohol that is covalently bonded to the oxygen atom.
C. and the hydrogen atom of allyl alcohol that is covalently bonded to the carbon atom.
d. Actually, hydrogen bonding is NOT the intermolecular force between allyl alcohol and
water
Hydrogen bonding interaction occurs between the oxygen atom of water and the hydrogen atom of allyl alcohol that is covalently bonded to the oxygen atom.
We must recall that allyl alcohol is a molecular substance. Molecular substances do not dissociate into ions in water. As such particles of allyl alcohol remain intact when dissolved in water.
Hydrogen bonding occurs when hydrogen is bonded to an electronegative atom such as oxygen. In allyl alcohol, hydrogen bonding interaction occurs between the hydrogen atom of water and the oxygen atom of allyl alcohol.
Also, hydrogen bonding interaction occurs between the oxygen atom of water and the hydrogen atom of allyl alcohol that is covalently bonded to the oxygen atom.

a vessel contains 66 g co2 and 16 g o2 at a pressure of 10.0 atm. what is the partial pressure of co2?
This question is providing the masses of carbon dioxide and oxygen gases at 10.0 atm as 66 g and 16 g respectively, and is asking for the partial pressure of the former which turns out to be 7.50 atm after doing the math.
Thus, we can start solving this problem with the Dalton's law approach, in order to make a relationship for the total pressure, partial pressure and mole fraction, which means we must first determine the mole fraction of carbon dioxide gas in the mixture as shown below:
[tex]x_{CO_2}=\frac{n_{CO_2}}{n_{CO_2}+n_{O_2}}[/tex]
Next, we calculate the moles of both gases by dividing the grams over the molar masses:
[tex]n_{CO_2}=\frac{66g}{44.01g/mol} =1.50mol\\\\n_{O_2}=\frac{16g}{32g/mol} =0.5mol[/tex]
Then, the mole fraction of carbon dioxide as the required one by plugging in the previously calculated moles:
[tex]x_{CO_2}=\frac{1.5}{1.5+0.5}=0.75[/tex]
Finally, we use the definition of the Dalton's law to calculate the partial pressure of carbon dioxide gas in the binary mixture:
[tex]P_{CO_2}=x_{CO_2}P\\\\P_{CO_2}=0.75*10.0atm\\\\P_{CO_2}=7.50 atm[/tex]

______________ is a durable material and is widely used for casting, which is a process by which the melted material is poured into a mold. A. Bronze c. Copper b. Silver d. Gold Please select the best answer from the choices provided A B C D.
The material that has been widely used in casting has been copper. Thus, option C is correct.
Casting has been the process of molding the liquid into a specific shape with the mold. The casting involves the heating of elements and converting them into liquid. The liquid has been poured into the mold and cooling results in the casted material.
The casted material has been selected based on the boiling temperature, cooling temperature, resistivity, cost-effectiveness, and damping ability.
The material that has been consisted of these characteristics has been copper. Thus, copper has been commonly used for casting. Thus, option C is correct.

A sample of tin (Cp = 0. 227 J/g•°C) is placed in a freezer. Its temperature decreases from 15. 0°C to â’10. 0°C as it releases 543 J of energy. What is the mass of the sample? Round your answer to three significant figures. G.
Taking into account the definition of calorimetry, the mass of the sample is 478.41 grams.
Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.
Sensible heat is defined as the amount of heat that a body absorbs or releases without any changes in its physical state (phase change).
So, the equation that allows to calculate heat exchanges is:
Q = c× m× ΔT
where Q is the heat exchanged by a body of mass m, made up of a specific heat substance c and where ΔT is the temperature variation.
In this case, you know:
Q= -543 J because the energy is releasesc= 0.227 [tex]\frac{J}{gC}[/tex]m= ?ΔT= Tfinal - Tinitial= 10 C - 15 C= -5 CReplacing:
-543 J= 0.227 [tex]\frac{J}{gC}[/tex]× m× (-5 C)
Solving:
[tex]m=\frac{-543 J}{0.227 \frac{J}{gC}x(-5 C)}[/tex]
m=478.41 grams
In summary, the mass of the sample is 478.41 grams.

Research the future of energy production. What improvements to (or new methods of) electrical energy production are scientists currently developing? How will they improve on present methods of energy production (what makes these new methods better than the old)? What are the cons of these improvements?
Answer:
Fossil fuels like coal, oil and natural gas supply 80 percent of the world’s energy to warm homes, charge devices and power transportation. They are also the primary human source of greenhouse gas emissions. Stanford scientists broadly agree that curtailing our use of fossil fuels would have significant benefits like improving health and reducing the number and severity of natural disasters, but it’s not yet clear what can replace them.
