Isopropyl alcohol is mixed with water to produce a solution that is 70% alcohol by volume. How many mL of each compound is present in 785 mL of this solution?
Answer:
x = 549.5ml
Explanation:
As per the given data,
Volume of alcohol = 70% (v/v) = 70 ml in 100ml solution
Volume of the compound present = 785ml
From the above given values,
x ml solute/785 = 70/100
x ml solute = 70*785/100
x = 549.5ml
therefore, the volume of solute is 549.5ml.

This graph shows the titration of 35.0 mL of ethylamine solution with 0.0816 M HCl . Titration of ethylamine with HCl A titration curve shows p H decreasing with volume. The drop in p H is gradual for most of the curve, then p H drops steeply over a smaller volume change, then levels off at a low p H. The steep drop in p H occurs when 20 milliliters to 22 milliliters of H C l have been added. The p H drops from 6.0 to 1.0 over this range. Determine the molarity of the ethylamine solution.
By the definition of molarity, 1000ml of HCl solution contains 0.0858 moles of HCl.
The moles of HCl in 21ml of solutions can be obtained as follows-
Moles of HCl = 21ml *0.0858moles/1000ml
= 0.0081moles
Hence, moles of ethylamine =0.0081moles
Now,
the molarity of ethylamine solutions can be obtained as follows-
Since,
35ml of ethylamine solution contains 0.0018moles
the moles of ethylamine in 1000ml of the solution(molarity) can be obtained as-
Molarity = 1000ml/L * 0.0018mol/35ml
= 0.0514 M
Hence,
the molarity of ethylamine solution is 0.0514 M
This is because, to find molarity of a solution considering a titration curve which is a plot of pH v/s volume of titrant. The equivalence point in the titration curve is the point at which there is a significant change in pH with small addition of titrant. At the equivalence point, the moles of titrant equal the moles of analyte.
The volume of the HCl solution added to reach the equivalence point is 21ml.
At this point, the moles of HCl = moles of ethylamine

A chemist measures the enthalpy change ∆H during the reaction COCl2(g)+4NH3(g)--->CO(NH2)2(s)+2NH4Cl(s). Then ∆H = -140 KJ.
Enthalpy ChangeThe amount of heat that gets released or absorbed during a reaction and that takes place under constant pressure is referred to as the enthalpy change. The sign for it is H, which can be read as “∆H.”
Note that only reactions carried out under constant pressure are covered by the phrase “enthalpy change.”
What distinguishes entropy change from enthalpy?The main distinction that comes in between enthalpy and entropy, which exists despite the fact that they are both components of a thermodynamic system, is that the enthalpy is expressed as the total amount of heat content whereas altogether the entropy is the level of disorder.
Simply put, what is enthalpy?The whole internal energy is represented by enthalpy. And volume times pressure. The enthalpy of a system cannot be measured, although enthalpy variations can be observed.

The 1.662 × 10¹⁸ protons per second will shine on the chemistry text from a 250 W bulb.
What is the photon?A photon or light quantum, is an energy packet of electromagnetic radiation. Einstein suggested the presence of discrete energy packets during the transmission of light and deduced that the light quantum is associated with momentum (hν/c).
A photon is defined as a discrete bundle of electromagnetic energy that also moves at the speed of light (3 × 10⁸ m/s).
The energy of a single photon with a wavelength (λ) of 550 nm can be calculated from the following equation:
E = hc/λ
Where h is Planck's constant has a value equal to 6.626*10⁻³⁴ J·s.
E = (6.626 × 10⁻³⁴ J·s × 3×10⁸ m/s) / (550 ×10⁻⁹m)
E = 3.614 × 10⁻¹⁹ J.
It means that the energy of one photon is equal to 3.614 × 10⁻¹⁹ J.
[tex]1J/s \times \frac{1photon}{3.614 \times 10^{-19} J.}[/tex]
= 2.77 × 10¹⁸ proton/s = 1 Watt
Given, a 200 W bulb converts 5% of its output into light, therefore

Donna wants to calculate the speed at which a sound wave is traveling. She knows that the frequency of the wave is 680 hertz and that the wave has a wavelength of 0.5 meters.
What is the speed of the sound wave?
The speed of the sound wave is 340 mrter per second.
f = frequency of sound wave = 680 hertz
λ = wavelength of sound wave = 0.5 meter
v = speed of the sound wave
We know that the velocity of a sound wave is given by
speed of sound wave = frequency wave of sound x wavelength of sound wave
v = f λ
Substituting the above values into the above equation
v = (680 hertz) (0.5 meters)
v = 340 meters per second
Therefore the speed of sound waves is 340 meters per second.
Sound waves are pressure waves. They can be seen as pressure fluctuations over time. Sound waves are transverse waves. To hear the sound of a tuning fork, the tines on the fork must move air from the fork to the ear. Most sound waves are produced by vibrating objects. Sound is a kind of energy produced by vibration.

using the molar ratio between the limiting reactant (aluminum) and the product copper determine the theoretical yield of copper
Using the molar ratio of the limiting reactant to the product, the theoretical yield of copper would be 192 grams.
What are limiting reactants?In chemical reactions, limiting reactants are reactants that limit the extent of reactions due to their limited quantities as compared to other reactants.
Thus, limiting reactant dictates the amount of product that is formed from reactions.
Considering the reaction:
[tex]3CuCl_2 + 2Al = 2AlCl_3 + 3Cu[/tex]
Aluminum being the limiting reactant has 2 moles. The copper, being the product has 3 moles. Thus, the mole ratio between the limiting reactant and the product is 2:3.
This means that for every 1 mole of aluminum that reacts, 1.5 moles of copper is produced.
3 moles of copper are produced from the reaction.
Recall that: mass = mole x molar mass
Molar weight of copper = 64 g/mol

Explain Dilution ?Dilution is the process of "lowering the concentration of a solute in a solution simply by adding more solvent, such as water, to the solution." Diluting a solution requires adding a solvent without adding a solute.
A popular way to make a solution of a given concentration is to take a higher concentration and add water until the required concentration is reached. Dilution is the term for this procedure. Dilution can also be done by mixing a higher concentration solution with a lower concentration. Since stock solutions are often obtained and stored in very concentrated concentrations, dilution of the solutions is a mandatory procedure in the laboratory.

A rubber object that floats in water weighs 9.0 x 10-2 N. What is the weight of the water it displaces?
Weight of water displaces is 9.0 × [tex]10^{-2}[/tex] kg.
By the help of Archimedes’ principle,
F = weight of water displaces
Given, F = 9.0 × [tex]10^{-2}[/tex] N
Hence, weight of water displaces is 9.0 × [tex]10^{-2}[/tex] kg.
Archimedes' principle states that a body immersed in a fluid is subjected to an upwards force same to the load of the displaced fluid. this is a first circumstance of equilibrium. We recall that the above force, referred to as pressure of buoyancy, is located in the center of the submerged hull that we name center of buoyancy.
He did supposedly get an concept as he sat down in a bath, but it wasn't approximately buoyancy that is the phenomenon on which his principle is based. Archimedes' principle states that any object, completely or in part immersed in a fluid, is buoyed up via a force equal to the burden of the fluid displaced through the object.
It is utilized in designing of ships and submarines. It is used in lactometers to determine the purity of milk. it is used in hydrometers to decide density of fluids. It is used in hydraulic lifts.

Draw the Lewis structure of Ch3Br. Include lone pairs of electrons
For a structure of the CH3Br structure, see attached image.
A covalent compound is represented by a lewis structure structure, in which valence electrons, lone pairs, and bonding electrons are represented by dots. Sir G.N. Lewis first described the method in his 1916 article "Atom and Molecule."
They are also known as molecular dot electron diagrams. The CH3Br molecule has fourteen electrons in total. As may be plainly seen in the attached image, each element's atom is surrounded by dots to represent its valence electrons.
