Answer: 1169.298 L
Explanation: In order to go from grams to liters, you must find the moles first using the molar mass, 62.068 g/mol (found via google search). I will assume the ethylene glycol is in gas form so we can use the 22.4 L per mol conversion.
Using dimensional analysis, starting with the kg, we must convert to grams, then moles, then liters.
[tex]\frac{3.24 kg}{} * \frac{1000g}{1 kg} * \frac{1 mol}{62.068 g} * \frac{22.4 L}{1 mol}[/tex]
Multiply the top individually, then the bottom individually.
[tex]\frac{72576}{62.068}[/tex]
Divide out.
[tex]= 1169.298 L[/tex]
In the end, we get 1169.298 L of ethylene glycol.

If the mass ratio of K to F in a compound is 2.06:1, how many grams of F are needed to react with 101g of K?
Mass of F to react with 101 g of K = 49.03 g
Further explanationProust stated the Comparative Law that compounds are formed from elements with the same Mass Comparison so that the compound has a fixed composition of elements
In the same compound, although from different sources and formed by different processes, it will still have the same composition/comparison
With this law, we can calculate how many grams an element is needed to make a compound with a certain mass, as desired
The mass of compounding compounds can also be calculated.
For example, the mass ratio of oxygen (O) and hydrogen (H) elements in H₂O remains at 8: 1. So if you know the amount of mass of oxygen you can know the amount of hydrogen and water mass.
The mass ratio of K to F in a compound is 2.06:1, so the mass of F to react with 101 g of K :
[tex]\tt =\dfrac{1}{2.06}\times 101\\\\=\boxed{\bold{49.03~g}}[/tex]
What is the periodic table arrangement?
Answer: the top to bottom are periods and left to right are groups
Explanation: the periodic table of elements arranges all of the known chemical elements in an informative array. Elements are arranged from left to right and top to bottom in order of increasing atomic number. Order generally coincides with increasing atomic mass. The rows are called periods.

The energy of a pendulum is recorded at different positions in the table below. Use the data in the table to determine the amount of kinetic energy the pendulum had at Position 2. dude i will give yall brainlest
Answer:
36.55 J
Explanation:
PE = Potential energy
KE = Kinetic energy
TE = Total energy
The following data were obtained from the question:
Position >> PE >>>>> KE >>>>>> TE
1 >>>>>>>> 72.26 >> 27.74 >>>> 100
2 >>>>>>>> 63.45 >> x >>>>>>>> 100
3 >>>>>>>> 58.09 >> 41.91 >>>>> 100
The kinetic energy of the pendulum at position 2 can be obtained as follow:
From the table above, at position 2,
Potential energy (PE) = 63.45 J
Kinetic energy (KE) = unknown = x
Total energy (TE) = 100 J
TE = PE + KE
100 = 63.45 + x
Collect like terms
100 – 63.45 = x
x = 36.55 J
Thus, the kinetic energy of the pendulum at position 2 is 36.55 J.
Consider the equation below

The equilibrium constant : Kc=[CO₂]
Further explanationThe equilibrium constant is the value of the product in the equilibrium state of the substance in the right (product) divided by the substance in the left (reactant) with the exponents of each reaction coefficient
The equilibrium constant is based on the concentration (Kc) in a reaction
pA + qB -----> mC + nD
[tex]\large {\boxed {\bold {Kc ~ = ~ \frac {[C] ^ m [D] ^ n} {[A] ^ p [B] ^ q}}}}[/tex]
Solid (s) and liquid (l) are not included in the calculation of Kc(only aq-aquoeus and g-gas)
From reaction
CaCO₃(s)⇔CaO(s)+CO₂(g)
Because CaCO₃ and CaO are solid, only CO₂ is included in the calculation
[tex]\tt Kc=[CO_2][/tex]
A teacher wrote the following part of a balanced chemical equation Cu+2AgNO3
Answer: Cu + 2AgNO3 -> 2Ag + Cu(NO₃)₂
Explanation: Assuming the teacher wants you to finish the other side of the balanced equation, here is how I would do it.
I would consider this a Single Replacement equation. This means Ag will be Replaced with Cu. Using the chart provided, it can be seen that (NO₃) has a charge of ⁻ ¹ . Therefore, it can be assumed that Ag as a ⁺¹ charge as well. However, copper has a charge of ⁺² (we know this because there are 2NO3 in the first equation and therefore there needs to be 2 when copper replaces it) so when replacing Ag with Cu, some butterfly subscript multiplication needs to happen like the picture attached. So, finally, the equation is:
Cu + 2AgNO3 -> 2Ag + Cu(NO₃)₂
What is a double displacement reaction?

How is electromagnetic spectrum ( wavelength & frequency) used to make calls on our cellphones?
Answer:
Cell phones use radio waves to communicate with cell towers, and these waves have wavelengths of approximately 10-1000 m, which are much too large to be ionizing. WiFi actually operates at quite precise frequencies, either 2.4 GHz or 5 GHz, which correspond to wavelengths of either 12 cm or 6 cm.
Explanation:
When the mobile phone is turned on, it emits radio waves that consist of radio frequency (RF) energy—a form of electromagnetic radiation moving at the speed of light. It works by transmitting radio wave signals to (and receiving these from) nearby base stations.
Which of these is NOT true about the outer core? Question 4 options: It is mostly made up of iron and nickel. It is mostly liquid. It has a higher temperature than the inner core. atoms within it form a powerful magnetic field.
Answer:
Of the mentioned statements the incorrect statement is that it has a higher temperature than the inner core.
Explanation:
Both the outer and the inner core are formed of identical constituents chemically, that is, both are formed majorly of iron, with some quantity of nickel and some other chemical constituents. The difference is that the inner core is solid, while the outer core is liquid in the state. As one goes deeper, both the pressure and the temperature because of the weight of the overlying rock gets an increase.
The outer core is liquid in the state as the temperature is so much that the melting of iron takes place. However, the inner core is hotter in comparison to the outer core, but it is solid as the pressure is so much that it makes the atoms of the constituents to come so close to each other that they turn solid.
Answer:
It has a higher temperature than the inner core.
Explanation:
The inner core is indeed hotter than the outer core, is mostly composed of liquid iron and nickel, and magnetism in the outer core is about 50 times stronger than it is on the surface.
A tank of oxygen has a volume of 40.0L and is held at a pressure of 159atm at 25∘C. What volume of O2 gas (in liters) would there be at normal body conditions, or 1.00atm and 37∘C?
Answer:
V2 = 6616 L
Explanation:
From the question;
Initial volume = 40L
Initial Pressure, P1 = 159atm
Initial Temperature T1 = 25 + 273 = 298K (Upon converting to Kelvin unit)
Final Volume, V2 = ?
Final Pressure, P2 = 1 atm
Final Temperature T2 = 37 + 273= 310K (Upon converting to Kelvin unit)
These quantities are related by the equation;
P1V1 / T1 = P2V2 / T2
V2 = T2 * P1 * V1 / T1 * P2
V2 = 310 * 159 * 40 / (298 * 1)
V2 = 6616 L
A piece of word has a mass of 3.16 g; when placed in 20.0 mL of water, the water volume increased to 23.4 mL. What is the density of this piece of wood?
Answer:
0.93g/mL
Explanation:
Given parameters
Mass of wood = 3.16g
Initial volume of water = 20mL
Volume of water + wood = 23.4mL
Unknown:
Density of the wood = ?
Solution:
Density is the mass per volume of a substance.
It is mathematically expressed as;
Density = [tex]\frac{mass}{volume}[/tex]
Volume of wood = 23.4mL - 20mL = 3.4mL
So,
Density = [tex]\frac{3.16}{3.4}[/tex] = 0.93g/mL

A piece of unknown metal absorbed 790.24 J of heat as it was heated from 40.0°C to 72.0°C. If the piece of metal weighed 55.0 g, what is the identity of the metal?
Answer:
Given metal is iron
Explanation:
Given data:
Heat absorbed = 790.24 J
Initial temperature = 40.0 °C
Final temperature = 72.0 °C
Mass of metal = 55.0 g
Identity of metal = ?
Solution:
Specific heat capacity:
It is the amount of heat required to raise the temperature of one gram of substance by one degree.
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = 72.0°C - 40.0°C
ΔT = 32 °C
790.24 J = 55 g ×c × 32 °C
790.24 J = 1760 g. °C ×c
c = 790.24 J /1760 g. °C
c = 0.449 J/g. °C
The specific heat capacity of iron is 0.449 J/g. °C thus, given metal is iron.
