Explanation:

When copper is heated with an excess of sulfur, copper(l) sulfide is
formed. In a given experiment, 0.0970 moles of copper was heated
with excess sulfur to yield 5.59 g copper(1) sulfide. What is the
percent yield?

Answers

Answer:

72.4%

Explanation:

Step 1: Write the balanced equation

2 Cu + S ⇒ Cu₂S

Step 2: Calculate the theoretical yield, in moles, from 0.0970 moles of Cu

The molar ratio of Cu to Cu₂S is 2:1.

0.0970 mol Cu × 1 mol Cu₂S/2 mol Cu = 0.0485 mol Cu₂S

Step 3, Convert the theoretical yield to mass

The molar mass of Cu₂S is 159.16 g/mol.

0.0485 mol × 159.16 g/mol = 7.72 g

Step 4: Calculate the percent yield

We will use the following expression.

%yield = experimental yield/theoretical yield × 100%

%yield = 5.59 g/7.72 g × 100% = 72.4%

Answers

Answer:

2.41x10²¹ atoms

Explanation:

mass of nickel that are present in the coin can be determined Using ( 25% nickel) with j mass of coin= 0.942g )

mass of nickel = (0.942g) × (25/100)

= 0.2355g of Nickel

We need to convert this " gram" into " moles"

Mole= mass/ molar mass

Molar mass= 58.69 g/mol

0.2355 g) / (58.69 g/mol)

= 0.004 mol

We need to convert the moles to

number of atoms.

Avogadro's number= 6.023x10²³ atoms/mol

(0.004 × 6.023x10²³ atoms/mol)

=2.41x10²¹ atoms

What is precipitation?

Precipitation is defined as any liquid or frozen water which forms in the atmosphere and then gets received on Earth.It is one of the most important steps of the water cycle.

Precipitation takes place in form of clouds when water vapor gets accumulated in clouds and they get bigger and heavy, when the clouds become heavy enough they fall to the land in the form of rain.f a cloud is present at higher altitudes , the water present in the clouds freezes and fall to the ground in form of snow,hail.

Precipitation occurs always in case of fresh water because the sea salt does not evaporate with the water.The different types of precipitation are rain, drizzle,snow,snow hail,etc.

Use the reaction below for the decomposition of sodium azide
to sodium metal and nitrogen gas.
2NaN3 (s) → 2Na(s) + 3N2(8)
What volume of nitrogen at STP is generated by the
decomposition of 130.0 g NaN3 ?

Answers

Answer:

34.05dm^3 of nitrogen gas

Explanation:

First things first, we need to find the number of moles of Sodium azide. We can do that by using the formula m=nM, mass = no. moles x Molar Mass

Rearrange to solve for no. moles and substituting in the known values and we have:

n = m/M

no. moles = 130.0g / (2x(22.99+3x14.01))

no. moles = 130.0/130.0 (4.s.f.)

no. moles = 1

Now we can use the ratio given in the equation to find the number of moles of Nitrogen that will be made:

1 x 3/2 = 1.5 moles of Nitrogen

Now we use the constant that 1 mole of any gas will always have a volume of 22.7dm^3 at STP.

1.5 x 22.7 = 34.05dm^3 of nitrogen gas.

A cylinder of compressed gas rolls off a boat and falls to the bottom of a lake. Eventually it rusts and the gas bubbles to the surface. A chemist collects a sample of the gas with the idea of trying to identify the gas. The wet gas collected occupies a volume of 283 mL at a pressure of 745 torr and temperature of 28.0oC. The vapor pressure of water at 28.0oC is 0.0372 atm. 1. Calculate the volume (L) that the gas occupies after it is dried (the water vapor removed) and stored at STP. Tries 0/99 The mass of the dry gas is 905 mg. A fragment of the tank indicates that the gas is a monoatomic element. 2. Write out the full name of the gas.

Answers

Answer:

See explanation

Explanation:

From the information given;

We convert the pressure from torr to atm as follows;

745 torr * 1 atm/760 torr = 0.98 atm

Initial pressure P1 =  0.98 atm - 0.0372 atm = 0.9428 atm

Initial volume V1=  283 mL

Initial temperature T1 = 28.0oC + 273 = 301 K

Final volume V2 = ??

Final Temperature T2 = 273 K

Final pressure P2 = 1 atm

From the general gas equation;

P1V1/T1 = P2V2/T2

P1V1T2 = P2V2T1

V2 = P1V1T2/P2T1

V2 = 0.9428 * 283 * 273/1 *  301

V2 = 241.99 mL or 0.24 L

If 1 mole of gas occupies 22.4 L

x moles of gas occupies 0.24 L

x =  1 mole  * 0.24 L/ 22.4 L

x = 0.0107 moles

But number of moles = mass/molar mass

molar mass = mass/number of moles

molar mass = 905 * 10^-3g/0.0107 moles

molar mass = 84 g/mol

What volume (in mL) of concentrated HCl (12 M) is needed to make 1500 mL of a 3.5 M solution?

Answers

Answer:

437.5 mL

Explanation:

Concentration (c) = Moles (n) / Volume of solution (liters)

C = n / V

rearrange the formula to find out how many moles you need in the final solution.

n (moles) = concentration (c)   x   Volume (V)   ( in liters)

Convert your mL into L.  1500mL is 1.5L

n = 3.5 moles/liter  x  1.5 liters  (the liters cancel each other out)

n = 5.25 moles

Now use the same formula to calculate the volume you need to make the final solution based on the concentration of the original.

c = n/V  or   V = n / c

V = 5.25 moles / 12 moles/liter     here the moles cancel out

V = 0.4375 L

convert back to mL

V = 437.5 mL

3. 0.402 mol

4. 0.506 mol

Explanation:

We can convert moles (n) to mass (m) using the following expressions that include the molar mass (M).

n = m/M

m = n × M

1. The molar mass of NH₄Cl is 53.49 g/mol.

m = 0.436 mol × 53.49 g/mol = 23.3 g

2. The molar mass of Ca(NO₃)₂ is 164.09 g/mol.

m = 0.50 mol × 164.09 g/mol = 82 g

3. The molar mass of NaCl is 58.44 g/mol.

n = 23.5 g/(58.44 g/mol) = 0.402 mol

4. The molar mass of KMnO₄ is 158.03 g/mol.

n = 79.9 g/(158.03 g/mol) = 0.506 mol

A 5.0 g sample of a pesticide was decomposed with metallic sodium in alcohol, and the liberated chloride ion was precipitated with AgCl. Express the results of this analysis in terms of percent DDT (C14H9Cl5, molar mass, 354.72 g/mol)) based on the recovery of 0.1606 g of AgCl

Answers

Answer:

1.59%

Explanation:

First, we convert 0.1606 g of AgCl into moles, using its molar mass:

0.1606 g ÷ 143.32 g/mol = 1.12x10⁻³ mol AgCl

Then we convert the calculated moles of Cl (equal to AgCl moles) into moles of DDT:

1.12x10⁻³ mol Cl * [tex]\frac{1molDDT}{5molCl}[/tex] = 2.24x10⁻⁴ mol DDT

Now we convert 2.24x10⁻⁴ moles of DDT into grams, using its molar mass:

2.24x10⁻⁴ mol DDT * 354.48 g/mol = 0.0794 g

Finally we calculate the percentage of DDT in the sample:

0.0794 g / 5.0 * 100% = 1.59%

Explanation:

We can solve this problem using Boyle's law, which states that at a constant temperature:

The subscript 1 stands for the initial conditions and 2 for the final conditions.

In this case:

P₁ = ?V₁ = 300.0 mLP₂ = 30.0 mm HgV₂ = 100.0 mL

We input the data:

P₁ * 300.0 mL = 30.0 mm Hg * 100.0 mL

And solve for P₁:

Consider the reaction of tin with potassium hydroxide and water.

Calculate the maximum mass (in grams) of potassium hydroxystannate, K2Sn(OH)6, that can be produced in the reaction. The limiting reactant is:

Answers

Answer:

The limiting reactant is: H₂O

265.3 g of K₂Sn(OH)₆ are formed in the reaction.

Explanation:

The reaction is:

Sn(s) + 2KOH (aq) + 4H₂O(l)  → K₂Sn(OH)₆ (s) + 2H₂ (g)

The first step to solve is to determine the moles of each reactant:

We controlled that reaction is ballanced.

122 g . 1mol / 118.71g = 1.03 moles of Sn

134g . 1mol /56.1g = 2.39 moles of KOH

63.9 g .1mol /18g = 3.55 mol of water

Stoichiometry is 1:2:4.

Sn is the lowest reactant and water, the highest, but I can see, that water is the limiting.

1 mol of Sn needs 4 moles of H₂O to react

Then, 1.03 moles of Sn may react to (1.03 . 4)/1 = 4.12 moles.

We only have 3.55 moles. It's ok.

2 moles of KOH need 4 moles of H₂O to react

Then, 2.39 moles of KOH may react to (2.39 . 4) /2 = 4.78 moles.

We only have 3.55, there's no enough water.

So 4 moles of water can produce 1 mol of potassium hydroxystannate

Then, 3.55 moles of H₂O may produce (3.55 . 1)/4 = 0.8875 moles.

We convert moles to mass: 0.08875 mol . 298.91g /1mol =265.3g
