If 36.5 m of a gas are collected at a pressure of 755 mm Hg, what volume will the gas
occupy if the pressure is changed to 632 mm Hg?
Answer:
Is there any answer options?, if not the answer is V2= 43.6m3
"The volume of the gas is calculated Boyles law. If 36.5 m of a gas are collected at a pressure of 755 mm Hg, then the volume of the gas will be 43.6 [tex]m^{3}[/tex]"
What is Boyles Law?
Boyle's law, also known as the Boyle–Mariotte law or Mariotte's law, would be an experimental gas law that specifies that how pressure of a gas decreases as the container capacity increases.
It can be represented by the formula:
[tex][P_{1} V_{1} =P_{2} V_{2}[/tex]
It is given that, [tex]P_{1}[/tex]= 755 mmHg, [tex]P_{2}[/tex] = 632 mm Hg, [tex]V_{1}[/tex]= 36.5[tex]m^{3}[/tex]. [tex]V_{2}[/tex]= ?
Now, put the value of given data in above formula:
[tex]V_{2}[/tex] = 755× 36.5/632= 43.6 [tex]m^{3}[/tex] .

what is the most important part of an Atom? Why?
Answer:
I would say proton and electron are the two most important subatomic particles in an atom
Explanation:
The number of protons inside a nucleus must equal to the number of electrons outside of the nucleus. This number determines all the chemical properties of the atom, which governs the behaviors of all matters in our world.

Describe the result of your procedure with both the coin and the nail. Include the reverse procedure you did with the coin
Answer:
The result of the procedure with the nail ended up going through reduction while the copper strip went through oxidation. The copper strip is the anode and the nail is the cathode. The anode is the + and the cathode is the - . Both the copper strip and the anode are placed in a tank filled with electrolyte solution. The direction of the flow goes from the positive to the negative (anode to the cathode).
Explanation:
I was doing the assignment too, hope this helps :)
The result of the procedure with respect to the coin and nail should be explained below.
What is result of the given procedure?Here the nail should be ended up through the decrease while on the other hand, the copper strip should be went through oxidation.
Here the copper strip should be considered as anode and nail should be considered as the cathode. Here the anode should be + while the cathode should be -.
Both should be placed in the tank that should be filled with the electrolyte solution.

what is the difference between a Stalagmite and a stalactite?
Answer:
A stalagmite is a type of rock formation that rises from the floor of a cave due to the accumulation of material deposited on the floor from ceiling drippings. Stalagmites are typically composed of calcium carbonate, but may consist of lava, mud, peat, pitch, sand, sinter and amberat.
and a stalactite means mineral formation that hangs from the ceiling of caves, hot springs, or man-made structures such as bridges and mines. Any material that is soluble and that can be deposited as a colloid, or is in suspension, or is capable of being melted, may form a stalactite.

objects?
Answer:
Astronomers use a number of telescopes sensitive to different parts of the electromagnetic spectrum to study objects in space. Even though all light is fundamentally the same thing, the way that astronomers observe light depends on the portion of the spectrum they wish to study.
Explanation:
Which are factors that affect the rate of chemical reactions? Select all that apply.
1.concentration
2.weight
3.temperature
4.surface area
Temperature and surface area are factors that affect the rate of chemical reactions. Hence, options C and D are correct.
What is temperature?Temperature is the measure of hotness or coldness expressed in terms of any of several scales, including Fahrenheit and Celsius.
The rate of a chemical reaction is affected by several parameters. Reactions involving two phases proceed more rapidly when there is greater surface area contact.
If the temperature or reactant concentration is increased, the rate of a given reaction generally increases as well.
Hence, options C and D are correct.

How many moles of Mg3(PO4)2 are in 350.00 grams of Mg3(PO4)2?
Answer:
1.3 moles/ 1.33150727 moles
Explanation:
350g x 1 mol/262.86g = 1.3 moles
The molar mass of Mg3(PO4)2 is 262.855 g/mol
Atomic weight of the parts:
Mg 24.3050 x 3 = 72.92
P 30.973762 x2 = 61.95
O 15.9994 x8 = 127.995
There are 262.855 grams in one mole, so
350.00 g x (262.855g/1 mole) = 1.33 moles Mg3(PO4)2

Jessica places 100. g of water at 20.0℃ in an insulated cup. The specific heat capacity of water is 4.18 J/(g℃). What is the final temperature of the water if 5000. J of energy is added to the water in the insulated cup?
Answer:
31.96°C
Explanation:
Given that,
Mass of water, m = 100 g
Initial temperature, [tex]T_i=20^{\circ} C[/tex]
The specific heat capacity of water is 4.18 J/(g℃)
We need to find the final temperature of the water if 5000. J of energy is added to the water in the insulated cup.
The heat added to the water is given by :
[tex]Q=mc\Delta T\\\\Q=mc(T_f-T_i)\\\\\dfrac{Q}{mc}+T_i=T_f\\\\T_f=\dfrac{5000}{100\times 4.18}+20\\\\T_f=31.96^{\circ} C[/tex]
So, the final temperature is 31.96°C.
