Using the balanced reaction equation, we can calculate that the mass of the precipitate will be 1.617 g.
To solve this question, we need to write the balanced reaction equation first:
2 NaF(aq) + BeSO₄(aq) → Na₂SO₄(aq) + BeF₂(s)
We can now see that the precipitate will be beryllium fluoride. We can also see that 1 mol of beryllium sulfate reacts with 2 moles of sodium fluoride. Now we can calculate the number of moles (n) of both reactants using their molarities (c) and volumes (V):
c = n/V ⇒ n = c * V
n(NaF) = c(NaF) * V(NaF)
n(NaF) = 4.988 M * 79.854 mL = 0.3983 mol
n(BeSO₄) = c(BeSO₄) * V(BeSO₄)
n(BeSO₄) = 1.471 M * 23.3760 mL
n(BeSO₄) = 0.03439 mol
We can see that n(NaF) is more than 2 times greater than n(BeSO₄), so NaF is in excess, and BeSO₄ is the limiting reactant. Now we can calculate the number of moles of BeF₂ formed:
1 mol BeSO₄ : 1 mol BeF₂ = 0.03439 mol BeSO₄ : X
X = 0.03439 mol BeF₂
We can now convert the number of moles (n = 0.03439 mol) of BeF₂ into mass (m), using the molar mass of BeF₂ (M = 47.01 g/mol):
n = m/M ⇒ m = n * M
m = 0.03439 mol * 47.01 g/mol
m = 1.617 g

n the laboratory you dilute 4.49 ml of a concentrated 12.0 m nitric acid solution to a total volume of 150 ml. what is the concentration of the dilute solution?
The concentration of the dilute solution is 0.3592 M.
Concentration, or the amount of solute in a solution, can either be expressed in molarity, M, moles of solute per liter of solution, or molality, m, moles of solute per kilogram of solution.
If the concentrated nitric acid solution is 12.0 M, then there are 12.0 moles nitric acid per liter of solution.
For a 4.49 ml of a concentrated 12.0 M nitric acid solution, the number of moles is 0.05388.
M = moles of solute / volume of solution
moles = 12.0 M(4.49 ml)(1 L / 1000 ml)
moles = 0.05388 moles nitric acid
If the total volume is 150 ml, then the concentration of the diluted solution is
M = moles of solute / volume of solution
M = 0.05388 moles nitric acid / 150 mL (1 L / 1000 ml)
M = 0.3592

(give the number with one digit after decimal point; no units)
The minimum mass of sulphur , in grams, needed to prepare 17.5 g of [tex]H_{2} So_{4}[/tex]is 53.5 gram
The molecular mass of eight molecules of sulphuric acid is 784 grams.
So 256 grams of sulphur makes 784 grams of sulphuric acid
That means 17.5 grams of sulphur can give
[tex]\frac{784}{256}[/tex] ×17.5 grams of sulphuric acid
And by solving this we get 53.5 grams.
That's how we determined the required grams of sulphur in grams.
The mass of a given molecule is its molecular mass (m), which is expressed in daltons. Because they contain various isotopes of an element, different molecules of the same compound can have distinct molecular masses. According to IUPAC, the related quantity relative molecular mass is a unitless comparison between the mass of a molecule and the unified atomic mass unit (also called the dalton).
The molar mass, which is expressed in g/mol, is defined as the mass of a given substance divided by the amount of a substance. That makes the molar mass an average of many particles or molecules, and the molecular mass the mass of one specific particle or molecule.

The mass number of this atom having 53 protons, 78 neutrons, and 54 electrons will be 131.
In the field of science, we can describe a mass number of an atom as simply a measure of the protons and neutrons that are to be found in the nucleus of an atom. In chemistry, the mass number is denoted by the letter 'A'.
In the above-mentioned case, the number of protons of the atom is 53 whereas the number of neutrons is 78.
In order to calculate the mass number, we will add the number of protons and neutrons. As the result of the addition of 53+78 is 131 hence, the mass number will be 131.

waste water treatment often has at least one oxidation-reduction step. in the collection of waste water, chlorine can be added to control corrosion by hydrogen sulfide to give sulfur and chloride ions. what is the balanced equation for the reaction that occurs in this step? include physical states in your answer.
The balanced reaction equation for this redox reaction looks like this:
H₂S(aq) + Cl₂(g) → S(s) + 2HCl(aq)
First, we write what we know about the reaction:
Hydrogen sulfide (H₂S) that is dissolved in the wastewater (so the physical state is (aq)) is reacting with gaseous chlorine (so Cl₂(g)) to form sulfur (which is solid at room temperature, and does not dissolve in water, so S(g)) and chloride ions (Cl⁻). To counter their negative charge, we add the hydrogen from H₂S to chlorides, which results in HCl, which is soluble in water, so the physical state is (aq):
H₂S(aq) + Cl₂(g) → S(s) + HCl(aq)
When we look at this equation we can see that it is not balanced, because we have 2 H atoms and 2 Cl atoms on the left, and only 1 of both on the right. The easiest way to rectify this is to add "2" in front of HCl, resulting in a balanced reaction equation:
H₂S(aq) + Cl₂(g) → S(s) + 2HCl(aq)

7. if 45.52 ml of a potassium permanganate solution is needed to titrate 2.145 g of iron(ii) ammonium sulfate hexahydrate, calculate the molarity of the kmno4 solution.
The molarity of a solution is calculated from the number of moles of solute and the volume of solution in liters. The molarity of potassium permanganate solution 2.145 g of iron(ii) ammonium sulfate hexahydrate is 0.121 M.
What is molarity ?Molarity is used to represent the concentration of a solution. It is the ratio of number of moles of solute to the volume of solution in litres. Molarity depends on the temperature also.
The number of moles of a solute can be calculated from the molar mass and taken weight of the solute.
The molar mass of iron(ii) ammonium sulfate hexahydrate = 392.1 g/mol
Taken weight of solute = 2.145 g.
Therefore, the number of moles of iron(ii) ammonium sulfate hexahydrate = 2.145 / 392.1
= 0.0054 moles.
Now, the molarity of the solution is calculated as follows:
Molarity of solution =( no.of moles of iron(ii) ammonium sulfate hexahydrate ) / volume
= 0.0054 /0.045 L
= 0.121 M
Hence, The molarity of potassium permanganate solution 2.145 g of iron(ii) ammonium sulfate hexahydrate is 0.121 M.

A total of 2269 balloons of 1.5 Liters volume and 1.25 atm pressure can be filled from the cylinder of volume 2.3 Liters and 1850 atm pressure.
The volume of the Helium gas is 2.3L and the pressure is 1850 atm at 25° Celsius.
The smaller balloons that has to be filled are of volume 1.5 L at the pressure 1.25atm at the same temperature of 25° C.
Because the temperature is conserved, so, according to Boyle's law,
When temperature is constant, the pressure and volume of the gas are inversely proportional to each other.
we can write,
P₁V₁ = P₂V₂
Let us say that a total n numbers of smaller balloons can be filled, so,
P₁V₁ = n(P₂V₂)
Where,
P₁ is pressure of bigger balloon,
V₁ is the volume of the bigger balloon,
P₂ is the pressure of the smaller balloon and,
V₂ is the volume of the smaller balloon.
Now, putting all the values,
2.30 x 1850 = n(1.5 x 1.25)
n = 2269
So, a total 2269 balloons can be filled from the bigger balloon to the smaller balloons.

Using the percentage by volume of the solutions given, we can calculate that we require 216 mL of 100% alcohol and 384 mL of 50% alcohol.
The percentages given refer to the percentage by volume (%V). We need to make 600 mL of 68% alcohol solution, by mixing a certain volume of 50% solution (A) and a certain volume of 100% alcohol (B). So, we know that:
A + B = 600 mL
We also know that the total volume of alcohol in the end solution needs to be:
0.68 * 600 mL = 408 mL
So, by extension:
0.50 * A + B = 408 mL
Based on the first equation, we can say that:
A = 600 mL - B
If we use that A in the second equation we get:
0.50 * (600 mL - B) + B = 408 mL
300 mL - 0.50 B + B = 408 mL
If we rearrange this equation we get:
B - 0.50 * B = 408 mL - 300 mL
0.50 * B = 108 mL
B = 108 mL / 0.50
B = 216 mL
A = 600 mL - 216 mL = 384 mL
So, we need 216 mL of 100% alcohol and 384 mL of 50% alcohol solution to get 600 mL of 68% alcohol solution.

Explain in detail how you can determine how many grams of iron oxide will be produced.
The mass of the iron oxide produced in the given chemical reaction is equal to 27.04 grams.
What is the limiting reagent?The limiting reagent in a chemical reaction can be described as that reactant that will decide the amount of the yield of the product. The reactant consumed first will confirm the completion of the reaction if the reactants are not taken in stoichiometry.
Given the chemical reaction of the formation of iron oxide:
4Fe + 3O₂ → 2Fe₂O₃
Given the mass of the iron = 15.4 grams
The moles of the iron = 15.4/56 = 0.275 mol
The mass of the oxygen gas = 3.6 grams
The moles of the oxygen gas = 3.6 /32 = 0.1125 mol
From the chemical equation, 4 moles of the Fe react with oxygen = 3 mol
Then 0.275 mol of the Fe will react with oxygen = 3/4 × 0.275 = 0.206 mol
Therefore, oxygen is the limiting reagent here.
