I need help with my homework I need help with number 3Given: 1 foot is equivalent to 12 inches Given: 1 yard is equivalent to 3 feet Given: 1 mile is equivalent to 5, 280 feet The number of yards in 0.45 miles is

Answers

Answer 1

Answer:

The number of yards is 792.

Explanation:

To convert 0.45 miles to yards it is necessary to use the equivalence from mile to feet, and then the equivalence from feet to yard:

[tex]0.45\text{miles}\cdot(\frac{5,280feet}{1\text{mile}})\cdot(\frac{1\text{yard}}{3\text{feet}})=792\text{yards}[/tex]

So, it is 792 yards.

How many atoms are in 140 moles of Gold?

Answers

Answer:862470.84

Explanation:

1 mole of substance is exactly equal to 6.023 × 10 ²³ molecules. 843.22 × 10²³ atoms are in 140 moles of Gold.

What do you mean by mole ?

The term mole is defined as the amount of substance of a system which contains as many elementary entities.

1 mole is equal to 6.023 × 10 ²³ molecules.

One mole of any substance is equal to 6.023 × 10²³ units of that substance such as atoms, molecules, or ions. The number 6.023 × 10²³ is called as Avogadro's number or Avogadro's constant.

The mole concept can be used to convert between mass and number of particles.

1 mole = 6.023 × 10²³ molecules ( Avogadro number )

Then 1 mole of gold = 6.023 × 10²³ molecules

140 moles of gold = 140 × 6.023 × 10²³

=  843.22 × 10²³ atoms

Thus, 843.22 × 10²³ atoms are in 140 moles of Gold.

Calculate the concentration of the solution in mass percent 178mg C6H12O6 in 4.91g H2O

Answers

In this question, we need to calculate the percent mass concentration of one solute in one solvent, and we have:

178mg of C6H12O6

4.91g of H2O

To calculate the mass percent concentration, we can use the following formula:

%mass = (mass of solute/mass of solution)*100

But first, we need to have both compounds in the same unit, so 178mg will be equal to 0.178g

Now we add these values into the formula:

%mass = (0.178/5.088) * 100

mass = 3.50%

The 5.088 is because 4.91 + 0.178

Which of the following describes how difficult it is to remove a valence electron from an atom of a particular element?
A: Electron Affinity
B: Ionization energy
C: Atomic Radius
D: Electronegativity

Answers

The term that describes how difficult it is to remove a valence electron from an atom of a particular element is electron affinity (option A).

What is electron affinity?

Electron affinity is the energy released when an electron is attached to an atom or molecule; used as a measure of its ability to form an anion.

It becomes harder to remove an electron when an atom has a net positive charge because the attraction that the nuclear charge exerts per electron gets larger.

It takes a large amount of energy to remove electrons from an element with high electron affinity, hence, electron affinity determines how difficult it is to remove a valence electron from an atom.

How many moles of water are in a 39.2 L container at 6.32 atm and 486 °C?

Answers

Step 1

Water is supposed to be in the gas phase and it is assumed that it is an ideal gas.

Therefore, it can be applied:

p x V = n x R x T (1)

p = pressure = 6.32 atm

V = volume = 39.2 L

n = moles = unknown

R = gas constant = 0.082 atm L/mol K

T = absolute temperature = 486 °C + 273 = 759 K

-------------------

Step 2

n is cleared from (1):

p x V/R x T = n

(6.32 atm x 39.2 L)/(0.082 atm L/mol K x 759 K) = n

3.98 moles = n

Answer: number of moles = 3.98 moles

An oxidation process occurs at the positive electrode during discharge, whereas a reduction reaction occurs at the negative electrode. Electrons from an external power source induce a reverse electrochemical reaction in the rechargeable battery.

Calcium does not readily oxidize in dry air at normal temperatures, but it oxidizes fast in wet air or dry oxygen at around 300°C.

Calculate percent volume/volume of a solution that contains 80 ml of methanol and 230 ml of water?

Answers

Answer:

Explanations:

The formula for calculating the percent volume/volume of a solution is given as:

[tex]\%v\text{/v}.=\frac{volume\text{ of solute}}{volume\text{ of solution}}\times100[/tex]

Given the following parameters

volume of solute (methanol) = 80mL

volume of solution = volume of water + methanol

volume of solution = 80mL + 230mL = 310mL

Determine the required percent v/v

[tex]\begin{gathered} \%v\text{/}v=\frac{80mL}{310mL}\times100 \\ \%v\text{/}v=\frac{800}{31} \\ \%v\text{/}v=25.81\% \end{gathered}[/tex]

We need to find the amount of grams of the formed products.

So, let's first convert the grams of each reactant in moles. Remember that the number of moles (n) can be found if we divide the given mass of the given compound by its molar mass. So,

[tex]\begin{gathered} n_{NaCl}=\frac{12.9gNaCl}{\frac{58.5gNaCl}{\text{mol}}}=0.22\text{molesNaCl} \\ _{} \\ n_{AgNO_3}=\frac{250gAgNO_3}{\frac{169.87gAgNO_3}{mol}}=1.47molesAgNO_3 \end{gathered}[/tex]

The limiting reactant in this reaction is NaCl. So, we're going to use the reaction's stoichiometry to find the amount of the products as follows:

[tex]0.22mol\text{NaCl}\cdot\frac{1\text{molAgCl}}{1\text{molNaCl}}\cdot\frac{143.32\text{gAgCl}}{1\text{molAgCl}}=31.53\text{gAgCl}[/tex]

Thus, there are 31.53g of AgCl formed.

Finally, let's find the amount of grams of product D (NaNO3):

[tex]0.22mol\text{NaCl}\cdot\frac{1\text{molNaNO}3}{1\text{molNaCl}}\cdot\frac{84.99\text{gNaNO}3}{1\text{molNaNO}3}=18.69\text{gNaNO}3[/tex]

Using the table of bond dissociation energies for A−B⟶A+B, calculate the enthalpy of each step and the enthalpy of the overall reaction.

Bromination of isobutane is a two‑step reaction.

The enthalpy of each step : step 1: ΔH = 34 kJ/mol. step 2 : ΔH = -99 kJ/mol  enthalpy of the overall reaction , ΔH = 65 kJ/mol.

Bond dissociation energy :

H - H = 436 kJ/mol

H - Br = 366 kJ/mol

Br - Br = 193 kJ/mol

(CH₃)₃C - H = 400 kJ/mol

(CH₃)₃C - Br = 292 kJ/mol

Step 1 : (CH₃)₃C - H   +   Br    ------>   (CH₃)₃C°    +   H - Br

ΔH = ∑ Bond broken - ∑ Bond form

ΔH = 400 kJ/mol - 366 kJ/mol

ΔH = 34 kJ/mol    

Step 2: (CH₃)₃C°   +  Br - Br ---->    (CH₃)₃ - Br    +  Br

ΔH = ∑ Bond broken - ∑ Bond form

ΔH = 193 - 292

ΔH = - 99 kJ/mol

overall reaction :

(CH₃)₃ - H  +  Br - Br ---->    (CH₃)₃ - Br   +   H- Br

ΔH = ( 400 + 193 ) - ( 292 + 366 )

ΔH = 593 - 658

How many grams of Iron are produced if 0.576 moles of Carbon dioxide are produced when Fe3O4 react with CO to form Fe and CO₂?

Answers

The mass of Iron produced by the reaction of given reactants will be 64.3 grams.

The balanced reaction is given as,

Fe₂O₃ + 3CO= 2Fe + 3CO₂

According to the chemical equation, 3 moles of carbon monoxide, CO, will react with 1mole of ferric oxide, Fe₂O₃, and produce 3 moles of carbon dioxide, CO₂

Now, we are given moles of carbon monoxide and asked for moles of Iron. This means that we will have to convert the aforementioned mole ratio that exists between carbon monoxide and carbon dioxide to a gram ratio.

If one mole of Iron has the mass of 55.845 g and one mole of carbon dioxide has a mass of 44.01 g, it follows that  reaction produces

44.01g of carbon dioxide for the every 55.845 g of Iron.

So for 1 moles of carbon dioxide the mass will be  44.01 g

For 3 moles it is 3× 44.01 =132.03 gram

1 mole carbon dioxide has 55.845 g iron

0.576 moles has 55.845×0.576

44.01×3 g of carbon dioxide = 132.03 g

55.845×2 g of Iron = 111.69 g

So in 0.576 moles it will get 111.69×0.576
